Barely worth writing a review on... No voice prompts unless you keep your phone on throughout the duration of the workout. So. Youre gonna lose a WHOLE lotta battery life. Even then the voice is soooo soft I can barely hear it. In fact, I cant say I can hear her at all. After that, the music comes back BLARING. So in order to use this app: no music can be played and the screen stays on the entire time. (YES, I followed the instructions to a T on how to make the voice prompts work) Doesnt keep track of my workouts. Says Ive only completed the first day. So each time I log into app I have to figure out which week/day Im on. Seriously. The app doesnt keep track. Basically- I open the app to see what I have to do, and then try to do it on my own because the app plays no role at all. And on days with tempo runs/intervals...that just doesnt work. Im getting a different app. One that works. I successfully completed the C25K app called get running and LOVED it. But they dont have a 10k version This one will be deleted after I complete my review. Dont wast your time.
