Android: Most of us read long articles and books on our Android devices, or otherwise need to keep our screens lit longer than the default setting allows. KeepItOn keeps the screen lit while the device is in your hand.
After downloading the app just launch and hit the "ON" button. Then set your auto-start, wake up after time off, and sensitivity preferences. Once you're done the app will keep the screen lit for as long as you need it. When you're ready for it to turn off, go back into the app and tap "ON" to display "OFF."
