Always On Clock

Always On Clock is an Android application that keeps a clock visible on the screen instead of letting the display go dark. It occupies the role that a built-in always-on display fills on some devices: the current time stays readable while the phone sits on a desk, a nightstand, or a dock, without the user having to wake the device to check it.

The application is published by Raidenxd2 under the MIT license, which permits reuse and modification of the source with minimal conditions. It targets Android only, so there is no desktop or iOS counterpart, and behaviour depends on how a particular device and Android version handle screen timeout and wake state. Manufacturer power-management policies can therefore affect how long the clock remains on a given handset. Users looking for a lightweight, single-purpose clock overlay rather than a broader lock-screen replacement are the intended audience.
