Black Chronometer

Free, simple stopwatch focused on extending the battery life (AMOLED)

Simple stopwatch developed with the following goals in mind:

* Extend your device's battery life, especially on AMOLED screens (tested on a Nexus 6P; after 30 minutes of usage battery level is still at 100%)

* Free & Open Source (https://github.com/pereorga/BlackChronometer)

* No ads

* No permissions required

Thanks to Josep Balcells for the original idea and testing.
