Chess Clock times your games and records each result for you, like a paper scoresheet. Chess groups can run their club in it too. A serious clock • Presets from bullet to classical, plus your last three controls one tap away • Fischer increment, US delay and Bronstein delay • Tournament stages ("after 40 moves, add 30 minutes") with a live countdown to the next stage • Accurate to the tenth of a second, immune to timer drift • Low-time warnings that scale to the control, with distinct haptics at each handoff, at ten seconds and at five • Clock sounds: a click on each move, ticks at ten seconds and at five, a tone when a flag falls. They play on silent; the speaker button turns them off • Big mirrored display, portrait and landscape; the waiting side dims so you know whose move it is • Two layouts: Face to face, or Side of the board, with both times facing one edge for a phone lying beside the board • Pause, then lock the phone: both times stay on the Lock Screen. Quit the app and the game is still paused when you come back An automatic scoresheet • Enter names once. The app records every finished game with result, control, move count and how it ended • Win / loss / draw totals per player, head-to-head for every rivalry • Tap any game for its move-time timeline: how long each move took, both sides. It marks the longest think and the sharpest time-trouble stretch Clubs, for real-world chess groups • Create a club, publish it, and let members find it by name or by scanning its QR code • A results table with continuous Elo ratings that the app updates as members play • Club nights with RSVP, a looking-for-a-game signal, and a recap you can share as an image • A rated member directory, an activity feed, and moderation tools for owners and admins • Time-odds suggestions when two rated members sit down together Friends and nearby play • Nearby phones find each other when you start a game, so you pick your opponent instead of typing a name • Exchange finished games with a nearby friend, phone to phone, with no internet involved Your data No account to create and no ads. The clock and scoresheet live on your phone. For clubs, the app uses your iCloud sign-in as your identity and stores club data (names, rosters, results) in Apple's iCloud. We run no servers. You can delete your club data from inside the app at any time. Backups Export everything the app holds to one file and keep it wherever you keep your files. Restore it on a new phone, or after a reinstall, and your record comes back. You encrypt each backup with a password you choose; without it, nobody can open the file. Chess Clock Pro (one-time purchase, no subscription) • Custom time controls: any base time, increment, delay style and tournament stage • Full match history and the move-time timeline for every game • Head-to-head breakdown of every rivalry • Six premium themes: Tournament, Ocean, Midnight, Blossom, Iris and Coral Chess Clock comes in 43 languages, from Arabic to Vietnamese.
