Chess Clock — Scoresheet

Back up every game, rival and club to one encrypted file that only your password opens. New phone or reinstall, your record comes back. No account, no ads.

Chess Clock is an accurate game timer that does what paper scoresheets do: it remembers. And now it gives your chess group a home.

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 • Big mirrored display, portrait and landscape; the waiting side dims so you know whose move it is • Pause survives everything: lock the phone and both times sit on the Lock Screen; quit the app and the game is still paused when you return

A scoresheet that fills itself in • 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, with the longest think and the sharpest time-trouble stretch called out

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 that updates itself when members play, with continuous Elo ratings • 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. Clubs use your iCloud sign-in as identity and keep club data (names, rosters, results) in Apple's iCloud, never on our servers, because we don't run any. 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. Every backup is encrypted with a password you choose, and without that password nobody can open it.

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

Whether it's blitz at the kitchen table, a club night at the pub, or a long weekend rivalry, Chess Clock keeps the time and settles the argument about who's winning.
