Dont buy unless ...

You want an app that is literally dangerous and requires disabling your phone. Ive used this app for a year now in both free and proversion two to three times a week so I think Ive given it a fair chance. The screen contrast is so poor its impossible to read in daylight. I actually sprained my ankle on the edge of the path once trying to read it while running. App will also stop running if you get a call or alert, so using it requires disabling your phone. App designers answer to that is locking the screen, which turns screen black with barely discernible instructions to tap 3 times to return to app, thats right you cannot see progress while screen is locked. Basically it turns your expensive smart phone into a crappy running app. I doubt the designer has ever used it outdoors. Really a poorly designed app that is dangerous and useless.
