iPhone
Recover interrupted games, undo mistaken presses, and play with a clock built for the board. The core clock is free; Pro is one purchase, with no ads or subscription.
DuelTempo is a precision chess clock for focused over-the-board games. Pick a familiar bullet, blitz, rapid, or classical control, place your iPhone beside the board, and tap after every move. The default 3+2 clock and full-half tap zones get a game running in seconds.
TRUST THE CLOCK
DuelTempo saves a live game locally and reopens it safely paused after an interruption. Undo one mistaken clock press exactly. Correct either player's time, apply quick penalty adjustments, and review a clear rescue log. Calls and app switching can pause the game automatically, and leaving a live game requires confirmation.
PLAY YOUR WAY
The free clock includes common sudden-death and Fischer controls, Obsidian & Ember, Odyssey, and Classic themes, precise touch handling, corrections, recovery, undo, move counts, and statistics.
DuelTempo Pro is one optional lifetime purchase. It unlocks eleven expressive themes: Marble, Gambit, Solstice, Aurora, Blueprint, Guilloché, Emberline, Deep Water, Signal, Shanti, and Modern, plus custom presets, time odds, multi-stage controls, Bronstein, US delay, and hourglass timing. There are no ads and no subscription.
FOCUSED AND PRIVATE
Game data and preferences stay on your device. DuelTempo has no account or ads.
Made for home games, chess clubs, cafés, schools, coaching, and casual OTB play. Event organizers may require dedicated approved equipment; DuelTempo does not claim tournament certification.
