I just started using this app, and was wondering if it will hurt battery life in the long run since you are running an app that uses accelerometer data all night long.
The only thing I've noticed (have used it for a few months now) is my phone reads 100% charge (I keep it plugged in) but its not really truly 100%. If I unplug it and plug back in, it begins charging for 5 extra minutes, then quits again.
