Works great when it works. But sometimes you need to re-enable it. Can you fix this ?

No longer stays awake Since update constantly having to wake phone up. When before the update all u had to do is turn the app on and that was it. Now every time I change screens from message, Internet, music player etc. The app turns off and I have to restart it. And I've also tried checking each app but it still doesn't work.

Well made app. I specially like the auto-on/off-via-usb-charging feature.

Great app. I was hoping someone came up with a solution to Android's flaws regarding this matter. I use it so that when I charge my phone wirelessly using inductive magnetic charging in its cradle, it does not sleep anymore! Better yet, there is an option do not dim the screen which even using developer mode for Android you cannot escape without caffeine! This app fixes both problems instantly. And you don't have to root your phone! Great job!

Great functionality The app does just what you expect, but there is a bug in my phone. Process is somewhat linked to a GooglePlay InAppBilling process, making the RAM usage ~250MB. Hope is fixed. Recommended app anyways :D
