Just tried the iOS version. A couple pieces of feedback: * On the "Dashboard" screen, the ligt reflection in the upper left of each dial was confusing at first. I thought it indicated something be aimed for in the central "compass". * The compass is also somewhat unclear as to which direction is better (if you've never used a compas before). I do see you addressed this in the "About" section of the app, but you could probably do something visually to make it more apparent.

Overall, great job. Sorry about the nits I picked :o)
