    I have used this app for years. It really captures what is happening an and allows you to fix it.

    This app was working great until the recent update. Now things will just not load, not work, stuck in endless loops etc. Like the memory free tool will be stuck @ 0% for one example. Using Cyanogen CM11 XNPQ32P

    This is one of those apps that makes rooting worth the trouble. It gives you granular control over apps & services. I used this with Better Battery Stats + Wakelock Detector to get standby battery drain < 1%/hr (no other kernel mods)
