Not recommended for anyone !
This is all i wanted... something to tell me when to stop and when to start while having a program were it intensifies while you go! Awesome!
This app sucks. Wish i could get my money back. After spendind 20 minutes calibrating... the jumps were still off by 20 percent.
It ok, nothing special, no real difference to run keeper, the only difference is you have to enter your timings manual on RK which takes second!
Excellent application: does exactly what you expect and want with ample versatility. Whether in the coaching or personal mode, it is though you had a personal trainer assisting.
