This is the second part in a series we’re doing on iMedicalApps. On a daily basis, there are plenty of free medical applications released for the iPhone and iPod Touch and most of them aren’t useful, hence the “free” tag.  Some of these free medical apps actually do provide key functionality.  This app review will cover four apps that meet the above criteria.  Remember, some of these apps are only free for a limited time.

Clearance

This is a quick and easy calculator for creatinine clearance.  Although there are other medical calculators that can do this calculation and GFR rates, having a dedicated app for this can be key, especially if you’re on your renal month.  Remember, the Cockroft – Gault formula doesn’t require height, so you don’t have to convert your patients height to centimeters(cumbersome), and can leave this part of the input blank.

AsthmaMD

This app was created by a physician, Dr. Sam Pejham, and is one you could consider recommending to your patients.  It has a nice user interface, along with many input options.  Patients can put in their medications, symptoms, triggers, and peek flow measures. You can even email-out reports to yourself, eventually sending the report to your physician if they accept such information electronically.  There is one caveat to remember with this app, in the iTunes description the developers state the application is free as of now, but they could eventually end up charging $9.99 to help cover the developmental costs. An app with such a beautiful user interface and loads of functionality definitely won’t stay free for too long.

Case Hx: General Medical History

This is a free and simple Medical history taking app.  It could be useful to first and second year med students learning how to take histories.  The app itself is extremely bare boned, but I actually liked its user interface and the tabs on the left side.
