There’s a lot of interest in the impact medical peripherals on iOS mobile platforms can have. Used properly, properly designed apps could help catch diseases earlier and make lives of patients easier. As the blogger covering health IT and medical software for Software Advice, I decided to see what it would take to design three apps myself. Through this exercise I learned about the challenges designers in mHealth face that might not be immediately obvious to those of us who’re commenting but lack practical experience. I’ll first discuss the three apps I came up with, before discussing what I learned.
