The program is great for a beginning runner to build stamina, regardless of what level they are starting from. We started at us, able to walk far distances but run zero. Week 3 was a good place for us to start and it feels good to see how much progress we make each week.
I do get frustrated with the app itself though. It pauses in my pocket even after I think I have the screen locked and does not accurately track distances ever. Often the screen shifts to the advertisements of the other apps the developers have to sell. When this occurs, I cannot get back to my workout screen. This is so irritating as I wobble behind my running partner trying to figure it out. I often have to shut it all down and reboot. It is essentially the same as the free app. I thought I would be less annoyed with the paid app, but no. I just want the timer and distance to function properly all the time.
I will keep using it until I find a more reliable app.
