Start playing — add a board for every game.
Clocks auto-save in this browser. Add as many boards as you need, then hit Tournament View for a full-screen wall.
Tournament timing in any browser.
Bullet through classical, Fischer increment, Bronstein delay, audio low-time alerts, multiple games at once. Works offline once loaded.
Multiple games at once
Run several chess clocks simultaneously — perfect for tournaments, clubs, or simul play across a few boards on a tablet.
Any time control
From bullet (1 min) through classical (multi-hour). Save your favorite formats as one-tap presets.
Fischer & Bronstein
Add time after each move (Fischer) or only when your clock dips below the increment (Bronstein delay). Both correctly implemented per FIDE.
Refresh-safe sessions
Clocks auto-save in your browser. Refresh or close the tab and come back — every running game stays intact at the exact tenth of a second.
Low-time audio alerts
Hear a warning at 30 sec, 10 sec, and on flag-fall. Never miss the flag, even when you're on the other side of the board.
Offline-first
No internet required once loaded. Coffee shops, parks, club rooms, plane mode — all fine.
Tap your side. Game on.
Setup takes under 30 seconds. The clock you didn't buy at the chess shop is already on your phone.
Name the players
Tap "Player 1" or "Player 2" to set names. Optional — defaults work for casual games.
Configure time
Settings (⋮) sets time per player and optional increment per move. Save tournament time controls as presets.
Tap to switch
After your move, tap your side to stop your clock and start your opponent's. The classic clap-the-button motion, on a phone.
Add more boards
"Add Another Game" spins up another clock for simul play, club night, or a side game between matches.
