Duo turns your iPhone or iPad into the clock beside the board — a real chess clock. The whole side is the button: tap it, slap it, palm it. A deep click, a proper clack, and a flag that falls. White plays on paper, Black plays on ink, so there is never a question of whose side is whose. Timing is timestamp-based and never drifts. Download and you are playing in seconds — no account, no onboarding, no ads. EVERY TIME CONTROL • Sudden death, Fischer increment, Bronstein and simple delay • Multi-stage FIDE controls (90 min / 40 moves + 30 min, with increment) • Per-player handicap and hourglass • Byo-yomi for Go and shogi, and overtime penalty scoring for Scrabble (Pro) • Built-in presets from bullet to classical, plus your own custom controls NEVER LOSE ON TIME IN SILENCE • Red low-time glow with tenths of a second under twenty seconds • Chimes at 60 and 30 seconds, a per-second tick under ten • Haptics you can feel through the table MADE FOR THE TABLE • Table Mode: lay the device flat and each half rotates to face its player, like a tournament clock beside the board • Works beautifully on iPhone and iPad, portrait or landscape • Pause for arbiter corrections: adjust either clock mid-game • The board decides: record wins, losses and draws that end over the board A CARD FOR EVERY GAME Every game ends with a designed, shareable game card — winner, moves, think times and the clock race in one image. Post it or save it to Photos.
