Caffeinate

Caffeinate is an Android utility for keeping a phone display awake during development work. It is intended for situations where repeated screen locking interrupts testing, observation, or interaction with an app under development. The application’s role is narrow: it helps maintain the screen in an on state so the device can remain visible and usable while a developer is working with it.

The program is published by AbdAlMoniem AlHifnawy and is distributed under the GPL-3.0-only license. The available platform information lists Android only, so it should be considered an Android-focused tool rather than a desktop or cross-platform application. Its usefulness is mainly in development and testing workflows where screen timeout behavior would otherwise get in the way.
