Tap Duel is a reaction-time game for iPhone and iPad. A solo Reflex Mode measures your tap-to-signal time to the millisecond and shows how you rank against players worldwide, a date-seeded Daily Challenge gives you one new goal every day, and real-time 1v1 duels — online via Game Center or pass-and-play on one device — turn the same test into head-to-head competition. All game data lives on your device; online duels use Apple's Game Center for matchmaking and leaderboards.
A round takes seconds. Beating your best takes all night.
The circle arms up. Hold your nerve — tap too early and the round is gone.
The instant it flashes green, hit it. Your reaction time is measured to the millisecond.
