About

Chess Clock & Game Timer

Features
Read full description

Chess Clock turns your iPhone or iPad into the clock that sits between two players. Two huge tap zones, no menus in the way, and timing that stays exact from the first move to the last. FOUR TIMING MODES - Sudden death: the classic. Run out and you flag. - Fischer increment: time is added to your bank after every move you complete. - Bronstein delay: you get back what you spent on a move, up to the delay. - Simple (US) delay: your main time only starts running once the delay is used up. READY IN ONE TAP Blitz 3+2, Blitz 5+0, Rapid 10+0 and Classical 90+30 are built in. Build and save your own for club nights, with any name and an optional move-limit label. BUILT FOR THE BOARD - Both halves are mirrored, so the clock reads right-side up from either side of the table. - A move counter for each player. - Undo the last tap when someone hits the wrong half. - Pause and resume without losing or gaining a single second. - The screen never dims or locks during a game. - Close the app mid-game and pick the position back up where you left it. EXACT, NOT APPROXIMATE The clock never counts ticks. Every reading is computed from timestamps, so a phone call, a notification or a trip to the home screen cannot make it drift. GAME HISTORY Every finished game is saved: the result, how long it ran, and how long each single move took for both players. Add a note, tag where you played and attach photos of the board or the scoresheet. CHESS CLOCK PRO Unlock four board themes and four flag alert sounds, and remove every ad. Pay once and keep it for good, or pick a weekly, monthly or yearly plan and cancel any time from your App Store settings. Works completely offline. No account, no sign-up, nothing to configure. Chess Clock is a timer for over-the-board play. It does not validate moves, enforce rules or record notation.
