Timer is a simple stopwatch and countdown app for Android. Create multiple timers and stopwatches, switch between list and grid layouts, drag to reorder or duplicate them, and open each item to edit the title, set duration presets (or custom minutes), and start, pause, or reset from a clear detail screen with a circular progress ring.
Build interval (HIIT) timers too: set a work and rest duration with a round count and the timer cycles through each phase, showing the current phase and round with a beep on each phase change and a 3-2-1 lead-in. While running a countdown you can quickly add or subtract time. Stopwatches support laps with an expandable lap list (saved between sessions) and an optional goal alert — with a progress ring toward the goal — that notifies you even when the app is in the background.
While a timer or stopwatch is running and you leave the app, ongoing notifications keep counts visible (system chronometer so times stay accurate without per-second app wakeups). When a countdown reaches zero, you get a finish alert — with Settings to control finish sound, vibration, and whether the alert repeats. Timers also recover after a reboot.
The UI follows Material 3 with light and dark theme (including dynamic color on supported devices) and is available in 10 languages. Open-source and third-party notices are in the in-app Licenses screen.
