Zazen Meditation Timer

Zazen Meditation Timer is an open-source meditation timer for Android, listed in MirrorNest’s Meditation category. It is designed for people who want to organize timed meditation practices on an Android device. A session can contain multiple timed sections for sitting, walking, or another practice, and demo sessions are created on first launch to provide a starting point.

Users can select from eight authentic bell sounds recorded from real Japanese rin bowls and a Tibetan singing bowl. Each section can specify its bell, number of rings, and interval between rings, while bell loudness can be adjusted for each session through bell dimming settings. Audio files can also be imported as custom bell tones from the Manage Bells screen. Long-pressing and dragging reorders sections, and swiping removes them.

During meditation, an animated arc shows section progress, elapsed or remaining time, and transitions between sections. Tapping the timer cycles through section elapsed time, section remaining time, session elapsed time, and session remaining time. The timer runs as a foreground service with a persistent notification, allowing it to keep time when the screen is locked or another app is in use. Sessions can be paused and resumed through the notification or the in-app controls. An optional keep-screen-on setting provides adjustable brightness, and the app supports light, dark, and system themes with Material You dynamic theming.

MirrorNest mirrors the official Android build directly on its own storage and scans it for malware before publishing. The app requires SCHEDULE_EXACT_ALARM for precise bell timing, POST_NOTIFICATIONS for the foreground service notification, FOREGROUND_SERVICE to continue timing in the background, and READ_EXTERNAL_STORAGE to import custom bell audio files. Its open-source license and Android distribution make it suitable for users seeking a configurable meditation timer within the Meditation software category.
