Jawbone UP24 vs Fitbit Force, a physician’s recommendation for best activity tracker

Editors Note — Fitbit has now recalled the Fitbit Force, please read this post to see why. We are no longer recommending the Fitbit Force be used by anyone. We thank the people in the comments section for their support and being outspoken on why the device needed to be recalled. 

In 2013, three companies (Fitbit, Jawbone, and Nike) made up 97% of the fitness tracker market. While my favorite tracker one year ago was the Nike FuelBand, the newly released Jawbone UP24 and Fitbit Force ran to the head of the class with class-leading battery life, third party connectivity, and robust feature sets.

Having personally tested many of the most popular fitness trackers, I’m often asked which is the best. My answer almost always comes down to the Jawbone UP24 or the Fitbit Force.

After spending a month going back and forth between the two options, I’ll share my answer.

The Contenders

The Jawbone UP24 ($149) and Fitbit Force ($129) are quite similar–they both are worn around the wrist, both add sleep and nutrition tracking, both offer silent/vibrating alarms, both feature passive/continuous Bluetooth syncing, both offer 7 day battery life, and both offer excellent third-party integration. Regardless, spending time with the two devices reveals that each has a different personality and approach to the quantified self movement.

A quick comment about the competition. I love the Nike FuelBand SE ($149), and it was formerly my preferred device, primarily due to the beautiful LED display and ability to function as a watch. However, the FuelBand’s limited 3rd party support and lack of sleep/nutrition tracking grew frustrating, especially at this point in the evolution of fitness devices.

The Basis Band ($199, review here) is currently the only other player in the market that I would consider over the Fitbit Force or Jawbone UP24. I love its accuracy (especially its ability to automatically track sleep) and additional sensors such as heart rate and perspiration, but it’s steep price tag, short battery life (4 days), and lack of third party support keep me from recommending it to people interested in casually joining the quantified self movement.

Form Factor and Hardware Design

side-by-sideSide View: Jawbone UP24 (Left), Fitbit Force (Right)

The UP24 and Force are worn around the wrist. The UP24 clings snugly around the wrist like a bracelet, whereas the Fitbit Force utilizes a strap not unlike the adjustable clasps used by old baseball caps. Amazon reviewers have been particularly frustrated with the Force’s strap, complaining of its tendency to come loose. In my experience, the strap functioned perfectly fine 95% of the time.

However, the occasional but consistent instance where the Force’s strap gets tugged loose makes me question why Fitbit didn’t just opt for the traditional watch strap. As pictured, the UP24 is sleeker than the Force, especially on its tapered side.

overviewTop View: Jawbone UP24 (Left), Fitbit Force (Right)

The most significant design difference is that the Fitbit Force’s increased size allows for a digital display, which can toggle through various displays: time, steps, distance, calories, active minutes, and floors climbed. The display is crisp and easy to read, and allows the Force to serve as a watch, which provides extra incentive to be worn every day. Unfortunately, the display requires the press of a button to turn on, unlike the always-on display of a standard digital watch. Furthermore, the Force’s primary clock display shows no indication of daily activity progress, requiring you to press the button a second time to switch the display if you want to see how close you are toward reaching your goal. For comparison, the Nike FuelBand’s strip of rainbow colored LED’s under the time provides an instant glimpse of how many steps one has traveled.

While the UP24 lacks a screen, the absence is not all bad. The UP24 is noticeably sleeker than the Force, and with automatic continuous syncing via Bluetooth, the iPhone app essentially becomes the Jawbone’s screen. In turn, the user interacts more frequently with a visually rich app, which is more immersive than any simplistic display on the band itself could provide.

    HATE HATE HATE the %$#@ Force’s clasp. When you pay over $100 for something you do NOT want to accidentally lose it due to the manufacturer’s choice of arm band. However, I do like the display and it’s sleekness on my arm.

    • Iltifat Husain, MD February 6, 2014 at 9:58 pm #

      so overall, you’re a fan?

      • Sondra Wellington February 13, 2014 at 7:09 am #

        My band kept falling off and I finally lost it in less than three months

    • David Ahn, MD February 7, 2014 at 2:30 am #

      @Kathy Nieder, i definitely agree. I do find Fitbit’s decision to go with the Force’s clasp quite puzzling.

    • Peter G July 6, 2014 at 8:21 pm #

      I agree! I had the Force and unfortunately, I recently lost it as the band unclaspsed without me realizing it. Went for the Jawbone Up24 this time. Like the design and it stays on!

  2. Patty D February 6, 2014 at 5:13 pm #

    Hi – the Force is great but as a physician you probabaly will be interetsed to learn that some people are developing severe contact dermatitis after wearing it for a few weeks, under where the battery touches their arm. This is in the news and also on the fitibt discussion forum. it’s a shame because it is a really nice device but people should be aware of this health risk.

    • Iltifat Husain, MD February 6, 2014 at 9:58 pm #

      could you provide links to where this is actually happening. one would think you can get contact dermatitis to really any type of device’s plastic.

      • Patty D February 6, 2014 at 10:21 pm #

        Sure. If you log in to the Fitbit Site which is free and search for “burned arm” you will get to the 120 pages of comments from people who all have the rash all exactly where the battery touches their arm. I am one of those people. Also google Fitbit rash for some news coverage. Photos in both places show how nasty the rash van be.

        • Iltifat Husain, MD February 7, 2014 at 1:08 am #

          And the Jawbone doesn’t have this issue?

    • David Ahn, MD February 7, 2014 at 2:33 am #

      Patty, thanks for raising this issue. I saw this in scattered reports, and just this morning, my own sister (also a physician) told me that she thinks she is developing an allergic reaction. Thankfully, Fitbit has acknowledged this issue and is offering refunds or replacements for any users that are suffering this issue. Here’s a link to pictures of a more severe case:

      • David Ahn, MD February 7, 2014 at 2:34 am #

        @Patty D and @Iltifat, I believe this issue is unique to the Fitbit Force, as it has to do with a nickel allergy that is associated with the battery design. On the Jawbone, the charging area is housed under a removable cap and does not come in contact with the skin.

        • Iltifat Husain, MD February 7, 2014 at 3:09 am #

          Wow — what a ridiculous flaw. Was this an issue w/ an earlier design and have they fixed it? E.g. if you get a replacement, or if you buy it right now — can you be reassured this issue won’t arise?

        • R Maodus February 21, 2014 at 8:40 am #

          I purchased the fitbit force. Loved it, enjoy having the display on my arm. Very motivating. After two and a half weeks of wearing it I developed the burn like rash. I do not have sensitive skin or alergys. I contacted fitbit to notify them that this horrible ugly burn came up not gradually but immediately one day when I took my fitbit off. I still have a scare on my arm the size of a quarter. Fitbit tried to tell me that it was only a few people that this affected. Not true. GMA had a segment on in January that is was affecting fitbit wearers. Fitbit has not posted any warnings about this and they have not changed the product.

        • Stephanie September 6, 2014 at 6:01 pm #

          I have developed a pretty severe rash from the UP24 band. I believe there is a small area on the band where the metal button comes into contact with my skin. I am allergic to nickel and this has caused the rash.

        • Luke Armbruster September 8, 2014 at 9:57 pm #

          I’ve also had issues with the UP24 as far as rashes. I think it takes some time for the allergy to take effect but I’ve actually covered the cap with athletic tape which seems to help a bit. No problems for several months. Once it warmed up, I started developing rashes.

  3. Albert S February 6, 2014 at 10:52 pm #

    Have you tried re-sorting the display mode order? It looks like you can move the clock down instead of being on the top, maybe that way whatever you want to see first will be there when you push the button once.

    The clasp is a pain for sure, even to put it on. In the 3 weeks owning Force, it came off on me once, so I got this small velcro tie that I used to reinforce it. One nice thing, it acts as a bumper when I type or use the mouse.

    As for the rash, I wonder if people wear it too tightly/snugly? I wear mine one hole larger from snug, where I can still fit my finger to snap the latch on. This allows the unit to slide almost 2 inches along my wrist.

    One thing I noticed too, when one is active, the sweat, water from hand washing might get ‘trapped’ by the unit, causing extended exposure where normally it would’ve gotten wiped off or dried off sooner.

    • David Ahn, MD February 7, 2014 at 2:37 am #

      @Albert, thanks for the suggestion. My issue is not necessarily the display order, per se. I still prefer to see the time first since I use it throughout the day as a watch, but some other trackers (FuelBand and Basis Band) show a progress bar on the same screen as the time so you don’t need to actually see the specific step count to get a feel for how close you are toward reaching your goal. It is a clean way of seeing two pieces of information at the same time.

    • burnedonce February 13, 2014 at 11:55 am #

      Hi Albert, as a rash victim, I can assure you I didn’t wear it too tightly. Also, I was pretty careful about keeping it dry and as it’s winter, and I am doing most of walking in the cold, there hasn’t been a lot of sweat… I’m also not allergic to nickel. The problem is with the unit not with the users. There are hundreds (or more likely at this point thousands) of people with this rash. People who are enjoying their Force and have been using it for a while think this is something that happens to someone else. Until it’s them. It can take 1-3 months before it occurs (maybe longer, nobody has had theirs longer than that so we don’t know) to occur, so nobody can assume they are beyond a safe point. This product is begging for a recall.

      • Albert S February 13, 2014 at 4:30 pm #

        Thanks for the info @burnedonce. I was mainly curious about the more detailed wearing style to see if there’s any commonalities. Yup, something is wrong with the Force’s design if this is happening to some people. I’ve been monitoring it on mine (and my wrist).

        I’ve even posted a suggestion on Fitbit’s FB… one to put the display lower, two to move the port to the side and/or seal cover it.

  4. Albert S February 7, 2014 at 2:42 am #

    Ah! Got it, David. I can’t imagine it being hard to do, adding 5 dots somewhere at the same display as the clock, being an OLED one. :)

    I wonder if the allergy problem can be solved by adding a rubber/plastic cap covering the battery contact points. Or as a temporary solution, cover it with a tape.

    I personally would like to see the display lower, to the inside of the wrist and the charging port can be on the side and covered.

    I wore the UP for about a week and also from what I’ve read, no allergies problem. Their material feels more rubbery too.

  5. David Ahn, MD February 7, 2014 at 5:10 am #

    @iltifat, as far as i understand it, this is not something that has been fixed, but i could be wrong.

  6. Jason Crosby February 7, 2014 at 8:56 am #

    Excellent Review. I’ve used both of these products consistently and can say you can’t go wrong with either. Really a shame Nike lacks integration support. Not being able to integrate with services like Runkeeper, loseit and is an absolute deal breaker.

  7. burnedonce February 11, 2014 at 10:05 am #

    The Force rash issue hasn’t been fixed, and there have been no announcements about identification of the cause. Based on user reports (people who are very allergic to nickel not having a problem, and having a rash and then testing negative for nickel allergies with an allergist), it doesn’t seem likely to be nickel. So people don’t know what is causing the rash. There are over 400 online posted reports to date.

  8. frank d February 12, 2014 at 8:09 pm #

    Thanks Dr Ahn for visiting with the affected people in the Fitbit community and offering to do a follow up article on the Fitbit Force.
    The symptoms on average appear after about a month of use. My spouse was affected as well, without being allergic to nickel. I pre-ordered the device as a gift, received early, in use late Nov, rash developed over the holidays.
    While Fitbit was quick to offer my family a refund, after an email with a picture of the rash, they have yet to issue any statement as to what the cause of the rashes / burns is.
    A lot of affected people are angered by the fact that the first issues date back to late November / early December, and Fitbit that has supposedly been investigating this for over a month now.
    Most agree that the Fitbit Force should have long been part of a recall, and all users should have been sent a stop using alert via email. But no, Fitbit keep mass marketing and selling to unsuspecting customers who are none the wiser about the health risk.
    All they did so far is put a little disclaimer up about a tiny percentage of people having the possibility of a rash due to a nickel allergy. Well, again, my spouse is not allergic to nickel. The rash worsened for two weeks after discovery and removal of the Force and now is most slowly starting to be less red and reduce in size.

  9. Kimy February 12, 2014 at 10:32 pm #

    I go the fitbit force for Christmas, after wearing it for 31 days, on/off at night, shower, etc. I developed a rash/burn and my wrist is still not healed. I took it off thinking it was just me, but my daughter wore it and had a small rash after 6 hours. Fitbit will refund/exchange my fitbit force, problem is I don’t have a case number and its been a week already. My rash got worse, before getting better and now my doctor says she wants to see me weekly until the rash is gone. It almost looks like a chemical burn, not a reaction or sensitivity to nickel as fitbit has suggested. There is a small % not sure the real numbers, but we know of 350+ and it keeps growing. There is no warning and fitbit keeps selling the force. Check it out on Facebook – burned by force. These are real people who enjoyed their fitbit force until they were burned.

  10. Karina February 13, 2014 at 2:44 pm #

    Also want to chime in to correct the perception that the rash / burn is due to a nickel allergy or wearing the band too tight or not cleaning it, etc. There are more than 2,000 comments on the Fitbit discussion forum from more than 400 people who have been affected (including me) – most of them are not allergic to nickel, many are cleaning it, most are not wearing it too tight (some people even got burned when they had the Force in their pants pockets). Most people end up getting medical treatment with diagnoses including contact dermatitis and second degree burns. It is serious. This product should not be on the market. Or if it is it should include a photo of the nasty burns some people get so buyers understand the risk!

  11. Lori February 13, 2014 at 5:30 pm #

    I too have a rash on both my wrists. The first rash appears quite a few weeks ago and was very disgusting looking. It got worse over a course of a few weeks after removing the device and I went to the dermatologist wondering what kind of crazy skin issue I contracted. I didn’t know at the time that it was from the force until I put it on my right arm since my left was so bad. After wearing for over a week a rash started and right away I realized this gross rash was from the force so I removed it immediately. The rash has gotten worse over the next week and I think has reached it’s peak. I still have both rashes and it has been quite embarrassing some of the looks I get at work. I’m sure people think I have some contagious skin problem so I usually have to keep it covered while at work.

    I hope they discontinue the sale until they fix whatever problem is causing this rash. I do not have a nickel allergy as they are claiming. I have worn various costume jewelry for a long time and never have I gotten a rash from it. I am hoping they pull the product before someone with a real sensitivity contracts it.

    Do you know how long this will take to heal completely?

    • David Ahn, MD February 14, 2014 at 1:08 am #

      Hi Lori, I can not say with confidence how long it will take. Please stop wearing the device if it is causing an allergy, and it should recover over time. I would imagine it should be in the days to weeks timeframe, but I can not say with certainty. If you have any additional concerns, do not hesitate to consult a physician or dermatologist. Thanks!

  12. Tony February 15, 2014 at 2:20 am #

    Good article. I like how it’s broken down into features/sections.

    Just to let you know, there is an Android app available for the Jawbone band, since March 2013. It would be helpful to your Android readers if the article was updated to reflect this.

    Also, the Jawbone app was not a complete redesign when the UP24 band was released. It was just updated to support the new UP24 band’s wireless syncing along with a few other new features. The existing app design has been around since 2012 when the second generation of the UP band was released. The UP24 band is the third generation of the UP device.

    As a long time UP user thinking about trying the Fitbit Force, your article has proven the UP is a better fit for me, especially with the recent skin problems from the Force.

    Thanks for your research!

  13. April February 21, 2014 at 10:28 pm #

    I am thankful foe the reviews as well as the comments. I have a 1st generation Nike Fuel band and I keep developing a horrible rash/burn. I do have a nickle allergy. After reading this and the comments I am torn between a Bia Sport and a Jaw Bone Up.

  14. Lance February 21, 2014 at 10:32 pm #

    Fitbit is recalling all Force bands due to the rash. So I guess that settles any debate until then.

    • Iltifat Husain, MD February 22, 2014 at 8:29 pm #

      ha, true.

    • marie March 19, 2014 at 1:25 pm #

      not just recalled the Force … stopped selling them.

  15. Brian Edwards MD February 25, 2014 at 5:29 pm #

    Question: Do all people have same metabolic rate? I am 62 yo. Does the software figure a 2% reduction in metabolism for each decade? I am a reduced obese. I lost 80 pounds and gained back 50 pounds. When I have tested my resting metabolic rate it is below normal. This energy gap I have developed should be accounted for in the software. Yesterday I hit 92% of my UP goal for the day. 9,270 steps, 4.44 miles walking. My active burn was 710 calories. My resting burn was 2,027 calories. I love my UP24 and suggest it for everyone especially for the sleep app., but the absence of different metabolic rates in the software is a major flaw.

    • David Ahn, MD February 26, 2014 at 1:17 am #

      You’re right Dr. Edwards. Estimating calorie burn is quite complicated, based on the variability of metabolic rates of people. As you might have very well learned to appreciate, I’ve found the utility of such fitness trackers is in the relative data (differentiating between a non-active day, a moderately active day, and a very active day) rather than the precision/accuracy of the objective data.

  16. Leslie Nolen February 25, 2014 at 8:16 pm #

    While positioned as a “physician’s recommendation” this post is virtually identical to the many consumer-oriented reviews of these products. It hasn’t filled a gap for physicians with novel information.

    I’d like to see a tracker comparison that actually offered doc-specific counsel on how to incorporate these gadgets into clinical practice and which device best suits various pt profiles. THAT would be new and worthy content.

  17. David Ahn, MD February 26, 2014 at 1:29 am #

    Hi Ms. Nolen, thanks a lot for your feedback. It’s always a difficult balance trying to gage how to best approach writing these articles, and it’s also challenging to present medical-grade recommendations on consumer-level devices. Your suggestions for “doc-specific counsel on how to incorporate these gadgets into clinical practice and which device best suits various pt profiles” would make for a very thought-provoking piece, and I’ll keep that in mind for future pieces.

  18. Patrick February 27, 2014 at 11:34 am #

    I have used trackers since about ’97 as an avid runner. I still use my Garmen310XT for cycling and very specific data relative to my exercise. I also have used the early Jawbone device(s), NikeFuel band, MyBasis and also the FitbitForce. I don’t care for the Jawbone as it lacks user data on the piece as I also like to look at the time. I liked the HR data on the MyBasis, but the size of the device made it uncomfortable to wear. Yes the FitBit Force has been recalled due to the skin reaction issue commented on above. Lets hope they redesign the clasp mechanism as well. So I use the NikeFuel Band as my daily device..
    There are a number of ventures working to enable MD’s and practices with user interface told that can be incorporated into a MD’s practice management.
    Good site, enjoyed reading everyones comments..

  19. Paul March 7, 2014 at 2:07 pm #

    Interesting read and nicely detailed. Like others, as a fitness enthusiast, I have used a multitude of fitness products by garmin, polar and timex. I easily have 7 HR straps at home for various products.There is a new band on the market made by Soleus called the Soleus GO activity tracker.I have been using their Soleus 3.0 GPS watch for 2 years.

    It has similar metrics as the jawbone and fitbit, but also features like the recently discontinued Fitbit Force with a stylish band that is comfortable allowing 24 hr use, nice clasp, LED display (time and date) and bluetooth capabilities.It is competitively priced $129.00 (though got mine at $124.00 at a local shop, Holabirds, which has an excellent website)
    The metrics include: distance, steps, calories, sleep tracker and it has an exercise mode, motion tracker (you can set a vibration alarm to encourage movement), and with the bluetooth capabilities: weather, phone # ID and messages are received on the LED display. I prefer NOT to enable these features, as my life is connected enough!
    I’ve only been using it for 48 hrs and I’m enjoying the data.
    The app is simple and basic and provides reasonable complete metrics. One IMPORTANT note, when I was considering purchasing my soleus 3.0 watch, I was torn between: polar, garmin, timex as I’ve had multiple versions of all of them. I actually called the soleus company, spoke with a “live” person and she even called me back 2 days later to update me on a question I had brought up during our conversation. I am a big fan of customer service.

    CONS: my iphone is only 4 version, so the bluetooth will not work with it, but it quickly recognized my ipad.Soleus is a smaller company with less brand recognition, but I’ve been very pleased with my watch for the last 2 years.

    **PLEASE note, I have no financial ties to the soleus company, but everytime before I invest in a fitness product, I scour the internet for reviews and often have a hard time finding reviews written by average consumers. I typically resort to and read the multitude of reviews seeking out the reviews with < 3 stars to find the CONS. I hope this is helpful for others who are considering purchasing an activity band.

    Last winter I bought a Fitbit Flex. I considered the Force, which was awaiting release, but decided against it because 1) I didn’t want to wait, 2) it was more expensive, and 3) it was wider and looked more clumsy. I love my Flex. I am diabetic and my A1C is in the 5.6-5.9 range, I’ve lost weight, and my cholesterol numbers are excellent. I exercise every day, and track my calories, carbs, fats, and protein by synching it with My Fitness Pal, and I monitor my blood pressure numbers and sleep quality. I am 64 and wish I’d had this little gadget years ago.

  21. BrumTaffy March 17, 2014 at 7:24 pm #

    Hi, I too have a Fitbit flex. I have used it since last November, I really like the gamification component and I have linked in with about 10 other users with whom to share the experience. I wonder if anyone will come up with a way to link users of a variety of trackers, so you have a wider group of friends to compete with/support?

    I am a physician. I really think trackers such as these are the future, both for staying healthy and also for managing conditions like diabetes. They work to motivate me :)

  22. John Madden March 20, 2014 at 9:29 am #

    I am 42 years old and a cardiac/brain injury patient. I used to run and exercise fairly regularly. Please share with me which one I should purchase Jawbone or Fitbit. I love keeping up with jogging routes, stats. Leaning toward the jawbone!

  23. Paul March 20, 2014 at 5:51 pm #

    John, 1st of all, congratulations on your committment to a healthy lifestyle given your prior medical challenges. I think that question (at least from my research) is difficult to answer. There seem to be 4 prominent players in the activity band market (and more), each with similar metrics (activity monitoring, sleep function, alarms, watch capabilities, move functioning, sharing capabilities, and now event HR syncing as well as active/passive bluetooth).
    The 4 options I reviewed were: Fibit (both “the One” and Fitbit “Flex”), Jawbone Up/UP24, Soleus “GO” and the Garmin “Vivofit”. I left out the Nike “Fuelband” as I didn’t like the concept of “fuel points” (just a personal prefernce). I think it depends upon what you are looking for in an activity tracker, and what your goals are ultimately.
    As a physician (and former exercise physiologist), I agree with BrumTaffy…these have so many important applications for health. I frequently suggest an activity tracker to MOST of my patients (obviously after being cleared by their physicians if required).
    One advantage of the Vivofit is HR [heart rate] monitoring capabilities. As a runner and cyclist, I’ve found HR to be a helpful measure in addition to perceived exertion to identify both: improvements in training effect and overtraining.
    I would suggest looking each type up, reading reviews from this website and amazon and identifying your wants and needs. Best of luck going forward.

  24. David Ahn, MD March 20, 2014 at 11:47 pm #

    Hi John, thanks for reaching out to us and reading the article. Obviously, I don’t know your medical history (nor would I recommend you to share it with everybody in open), so I agree that you should make sure a doctor that knows you clears you for exercise.

    between the jawbone or fitbit, i would have to recommend the jawbone at this point (given the rash issue with the fitbit force). i think they have the most well-rounded features. as one of our other readers suggested, there are other devices available (From garmin, etc) that I have not personally reviewed.

    keep in mind that most of these trackers do not have GPS, so your phone (via an app like Runkeeper) will be your best option when it comes to that.

    • Luke June 29, 2014 at 12:41 am #

      The Jawbone has an issue with rashes as well. It is a knickel allergy. The cap and the button are both coated in knickel. It takes about a month to start to develop (based on the many reviews I’ve read) and in my case, it took the heat and perspiration for it to start. It’s really frustrating as I am a golf instructor and I love everything else about the UP24. I should also note I have an IPhone. Just FYI.

  25. Dennis March 23, 2014 at 8:06 pm #

    Well, I guess I knew it was inevitable. I started with the Flex, really enjoyed all it offered and when they offered the Force, with enhanced functionality, I went for it. Immediately I started having problems with the clasp coming undone way too easily. The only solution I could find was to fasten as tight as I could stand to my wrist, to avoid it coming undone and falling off.

    Sometime yesterday, the clasp came undone and it is gone. I’ve retraced my steps, but to no avail. $129 gone. I notified the FitBit site of my concern and problem….never a word back on my issue.

    I’m hooked on the concept and will likely purchase another…………but not sure if it will be a FitBit.

  26. colleen April 29, 2014 at 2:13 pm #

    I am thinking I will buy the UP24, but I don’t have an iphone. with this be compatible with my HTC droid?

    • David Ahn, MD April 29, 2014 at 6:27 pm #

      Hi Colleen. You’re in luck! Jawbone added support for Android phones to the UP24 in March.

    I love my Up24 band!! It’s sleek, water resistant, tracks everything and gives you wonderful tips everyday!!!! It’s easy to pull on and off and comfy to sleep with.. LOVE how you can simply put your alerts in and it will alert your iPhone when to take vitamins or remember a work out! It even allows you to alert you via vibrating on your arm when you’re idle for too long (sitting at work).. Best investment I ever made and I highly recommend it!!!!

    Any comments on the continuous exposure to Bluetooth radiation from the Up24?

    I would have to say with the addition of Android support and the ability to purchase it for as low as $60 on Amazon, the UP24 is the clear winner in my book. The display is really not much of a selling factor considering how limited it is and after looking at the design of the strap, that alone is far too much of a negative for me to ever consider the Fitbit Force (now Charge). Really the only negative I have to say about the UP24 is my dislike of the food rating in the included app. I find it’s ranking of your food intake a bit arbitrary and not very beneficial for rating your overall food intake.
