Difficult to navigate

I love the idea of the app because it helps me pace myself and build up during runs or else I would run flat out and be worn out in 30 mins. I hate that it cant seem to figure a lot of it out. The app is difficult to navigate and when the phone auto locks it pauses it. Since I am running I dont notice then I have to unpause and I have run for way too long and get off time. Also, how do I look at previous sessions???
