About this app

Replace your chess clock with this free game timer! It's easy to use, yet fully featured to handle any time control. 100% free: no in-app purchases, no ads!

Choose your time control and you're ready to play. The 2nd player presses her button to start the 1st player's clock - and the game is on!

FEATURES - Large, easy-to-read buttons - Works in landscape and portrait on all devices - Quickly customize the app for one-tap access to all your favorite time controls - Time controls include base minutes per player and optional per-move delays or bonus time. The app supports both Fischer and Bronstein increments, as well as simple delays. The duration is up to you! - Supports multiple-stage time controls commonly seen in tournaments, such as "40 moves in 2 hours + game in 60 minutes." A glance at the clock shows your current stage! - Clock pauses automatically if the app is interrupted; manually pause the clock at any time - Pleasant sounds for buttons and "time's up" alert

At Chess.com, we really do love chess, and sometimes we even play it offline! For times like that, we created this clock - and we hope you love it as much as we do.

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 com.chess.clock 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

If the current release misbehaves, 1.2.0 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Chess Clock first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.

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 Chess Clock, and a listing is removed when the evidence for it stops holding up.
