PRT letting me down

Angie warned me that the running app she recommended is glitchy. She did not explain how, but I have already found out: the GPS won't record the entirety of your run and therefore stops counting distance. I guess I am already too deep into my training regime to start with another program. I could use also just use another pedometer, and I am not keeping track of how much I run, just trying to keep up with what "the coach" tells me to do.
