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.
