Compose Stopwatch1.9.1

Compose Stopwatch measures elapsed time and records laps for workouts, timed tasks, experiments, and other activities where precise intervals matter. Its configurable controls let users start, pause, resume, and add laps as they work. A setting can start the stopwatch automatically three seconds after launch, while an override lets the user choose a different start behavior.

Vibration provides tactile feedback during operation. The clock can be assigned to resume or pause the timer, resume while adding a lap, or do nothing when tapped. A circular indicator compares the current lap with the first one, and a dash on the lap progress marks the preceding lap. Screen-awake mode keeps the timer visible without letting the display fall asleep.

Portrait orientation provides more space for the lap list, while landscape orientation enlarges the time display. The interface follows the Material You theme, including a dynamic theme on Android 12 and newer devices, and offers an Extra Dark theme for AMOLED screens. Notification controls can be turned on or off; with notifications enabled, the stopwatch runs through LifecycleService and ForegroundService, while disabled notifications use ViewModel and DataStore.

Compose Stopwatch 1.9.1 is open-source software for Android in the Productivity category. It requires Android 8.0 or later and supports arm64-v8a, armeabi-v7a, x86_64, and x86 architectures. Its straightforward lap comparison and clock-tap controls make it suitable for people who need hands-on timing without leaving the active measurement visible.
