Brainfloss
A Pomodoro focus timer for Android. Twenty-five minutes of focus, five of rest, and a score for the day. The timer runs in a foreground service, so it keeps counting with the screen off and the app in the background.
Session history and daily scores are stored on your device. Signing in is optional and only exists to back that history up so it survives a new phone.
Brainfloss is launching on Google Play shortly.
