Chess Clock: Blitz & Timer

Chess Clock turns your phone into a beautiful, no-fuss game timer for two players — face to face, across the board. Lay it flat between you and play.

Tap your side when you've made your move. Your clock stops, your opponent's starts. That's it. Huge tap targets, instant response, zero fumbling — built for blitz.

TIME CONTROLS
• Sudden Death — set a time and play it down
• Fischer increment — seconds added back on every move
• Bronstein delay & US delay (Pro)
• One-tap presets for Bullet, Blitz, Rapid and Classical (1+0 through 90+30)
• Custom times and asymmetric odds for uneven matchups (Pro)

BUILT FOR REAL PLAY
• Two big tappable zones — the top side reads upside-down so the player across from you sees it the right way up
• The side on the move stays bright, the waiting side dims — always clear whose turn it is
• Flag detection with sound and haptics the moment time runs out
• Screen stays awake while you play; auto-pauses when you leave the app so no time leaks
• Move counters and end-of-game stats, then Rematch in one tap

NOT JUST CHESS
Works for Go, Shogi, Scrabble, checkers, backgammon — any two-player, turn-based game.

BEAUTIFUL & PRIVATE
• Clean light and dark themes (more in Pro)
• 100% offline — no account, no sign-up, no tracking, no ads
• Your games never leave your phone

Chess Clock Pro is a one-time purchase (no subscription) that unlocks Bronstein & US delay modes, custom times, asymmetric odds, all themes, and local game history.
