Android: There are few things more irritating than your phone constantly turning off when you're trying to read something on it. If you don't want to set your screen timeout to a stupidly long duration, Stay Alive can help fix this problem.
Stay Alive allows you to customise when your display turns on and stays on. You can choose to have it stay active while you're plugged into an outlet, or only for certain apps. The latter option can be particularly handy for reading or movie apps that don't already disable screen time-outs.
