Purpose of App Review

  • How useful is this app in helping users track their water daily water intake?


Most people know that drinking water throughout the day can have many health benefits.

Although the amount of water required each day varies from person to person, the common recommendation for the average adult is to consume at least eight 8 oz glasses of water a day.

However, for many people, remembering to drink water during their busy schedules might not come naturally and an app such as Ounces could have potential benefit for these individuals.

User Interface

The Ounces app is a very simple app geared towards helping users track how much water they have drank each day and to remind them if they have not met their daily goals.

The app can be configured by allowing the user to set daily goals for water intake. The app recommends that the user speak to their physician before deciding what their daily water intake should be.

Unfortunately, the app only allows the user to select a limit in 16-20 oz increments. The app also allows the user to turn on notifications which can remind the user to consume water throughout the day. This feature could be improved if it allowed the user to select what times they would like to be reminded.

On the main screen of the app, each time a user drinks water, they can add the amount by clicking the plus sign at the top right of the app. Once again, this app only includes 8oz increments which is not how much water a person drinks each time and might be better if they allowed the user to input their values in addition to the 8oz increment option.

Once a specific amount of water intake is added, the main screen fills up with blue water to depict how much of the user’s daily goal has been accomplished.

The app also sends push notifications to the individual’s phone so that they can be informed when they are behind on their daily goals. Once again, it would be useful if the user could determine how many times they want these notifications in a day and if there are specific times when these notifications would be more effective in their daily lives.

Evidence and literature used to support app

  • There is no concrete evidence supporting the suggestion of drinking eight 8 ounces glasses of water a day, research does suggest that 3.7 or 2.7L water should be consumed daily by men and women respectively based on the following study: Sawka MN, Cheuvront SN, Carter R. Human Water Needs. Nutrition Reviews. 2005;63:S30-S39.
