This Android app allows you to keep the display awake without having to change the device settings. It can be toggled at various places:
Coffee can be set as assist app (Device settings => Apps
=> Default apps
=> Assist app
) and changes it's state when assist is called.
From my point of view this app is feature complete. I probably won't add new major features on my own, but I will:
App strings and the app store description can be translated via Crowdin: https://crowdin.com/project/coffee-app
Translations have to be approved before being merged into the app. To become a translator with approval rights or to request a new language, please poke me on Crowdin or open an issue here on GitHub.
Coffee may not work because of an overly aggressive battery saver that is implemented by some OEMs (including Poco, Samsung and Xiaomi). In that case please enable "Alternate mode" in the settings.
