Zazen meditation timer with multi-section sessions and bell sounds.
About this app
Zazen Meditation Timer is a meditation timer for Android with customizable multi-section sessions, authentic bell sounds, and reliable background timing.
• Custom sessions — Build meditation sessions with multiple timed sections (sitting, walking, or any practice). Demo sessions are created on first launch to get you started. • 8 authentic bell sounds — Recorded from real Japanese rin bowls and a Tibetan singing bowl. • Per-section bell control — Choose which bell rings, how many times, and at what interval for each section. • Per-session bell volume — Adjust bell loudness per session through the bell dimming settings. • Custom bell import — Import your own audio files as bell tones from the Manage Bells screen. • Drag-and-drop editing — Long-press and drag to reorder sections; swipe to delete. • Animated arc timer — A custom ring visualization shows section progress, elapsed/remaining time, and smooth section transitions. • Multiple time displays — Tap the timer during meditation to cycle through: section elapsed, section remaining, session elapsed, session remaining. • Background timer — Runs as a foreground service with a persistent notification. Keeps reliable time even when the screen is locked or you switch apps. • Pause and resume — Pause your meditation and resume later from the notification or in-app controls. • Keep screen on — Optionally keep the display on during meditation with adjustable brightness. • Light, dark, and system themes — Supports Material You dynamic theming.
Permissions: • SCHEDULE_EXACT_ALARM — required for precise bell timing • POST_NOTIFICATIONS — required for the foreground service notification • FOREGROUND_SERVICE — required to keep the timer running in the background • READ_EXTERNAL_STORAGE — required to import custom bell audio files

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be at.priv.graf.zazentimer is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
No earlier build is on record for Zazen Meditation Timer, so there is nothing to roll back to yet. When a second version is published, this section will explain how to move between them safely.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Zazen Meditation Timer, and a listing is removed when the evidence for it stops holding up.
