Bi-polar app
Kind of a frustrating app - the underlying bones are simply fantastic, but the iOS implementation is amateur at best - to the point where I dont know how it made through App Store screening.
If you ignore the fact that your holding an iOS device and pretend you have a portable chart plotter, its a 6/5.
