Compose Stopwatch

Compose Stopwatch is an open-source stopwatch application for Android. It is listed in the Productivity category and is intended for users who need to measure elapsed time and track laps. The app provides configurable controls for starting, pausing, resuming, and recording laps.

Users can set the stopwatch to start automatically three seconds after launch, with an option to override that behavior. Vibration can be enabled for tactile feedback. Tapping the clock can be assigned to resume or pause, resume and add a lap, or perform no action. A circular display compares the current lap with the first lap, while a dash on the lap progress indicates the previous lap. Screen-awake mode keeps the stopwatch visible without allowing the screen to fall asleep.

The interface supports portrait and landscape orientations, with more room for laps in portrait and larger time text in landscape. Theme options include a dynamic theme on Android 12 and later and an Extra Dark theme for AMOLED screens. Notification settings can be enabled or disabled. When notifications are enabled, the stopwatch supplies notification controls and operates through LifecycleService and ForegroundService, while disabled notifications use ViewModel and DataStore.

Compose Stopwatch fits MirrorNest as an Android productivity utility distributed under an open-source license. MirrorNest mirrors the official build directly onto its own storage rather than presenting a separate repackaged edition. The mirrored build is scanned for malware before publication, giving Android users a catalog route to the official build with its platform, category, license, and distribution details clearly identified.
