Project

Grayout v1.5.0

An Android app that keeps your phone in grayscale, so it's a little less compelling to pick up. I designed and built it end to end.

  • Schedules by day and time, with a Today strip
  • Kept in color: Camera, Maps or Photos stay in color
  • Automatic restore turns gray back on after a few minutes
  • Quick Settings tiles
  • Fully on-device, no network access
