Caused Phone to Repeatedly Crash

I thought my phone was failing--I had constant reboots and battery failures. I ended up wiping my entire phone and reinstalling everything. My phone was fine until I installed this app, and then the repeated reboots started again. Something is wrong with this app. Now that Ive deleted it and rebooted, my phone is fine.
