Most iPhone cases just protect your phone from drops. If you’re getting fancy, it may have a fisheye camera lens or a screen-printed back. But what about diagnosing coronary heart disease, arrhythmia, or congenital heart defects? The AliveCor Heart Monitor is an FDA-approved iPhone case that can be held in your hands (or dramatically pressed against your chest) to produce an EKG/ECG--the infamous green blips pulsing patient-side in hospitals everywhere.

“We think that EKG screening can be as approachable as taking blood pressure,” AliveCor President and CEO Judy Wade tells Co.Design.

This adds to the growing list of medical devices in the stable mature gold standard IOS ecosystem. The best apps are written for the Iphone first and the Droid Iphone clones next maybe. 

If I were still writing code I would write for the windows 8 before I would put anything on a droid and watch it blow out my reputation. At least microsoft builds its own hardware and software so it has a chance at some stability and limited fragmentation. Not so with Droid DOA.
