Train your internal clock. Tap every second, stop at 10 blind, or pass-and-play with friends. 7 modes, leaderboards, daily streaks - one rule: trust your timing.
How good is your internal clock?
One Second is a minimalist timing game with one rule: trust your sense of time. No countdowns, no hand-holding — just you and the rhythm of a single second.
Start by tapping once every second. Then push further: stop a hidden timer at exactly 10 seconds, match a random target, or hold for precisely one second. The closer you land, the higher you score.
RHYTHM MODES
• Classic — Three lives. Find the beat and keep your combo alive.
• Precision — One life, razor-thin windows. For the steady-handed.
• Zen — No fail state, with a gentle metronome. Pure practice.
• Daily — One challenge a day. Build your streak.
ESTIMATION MODES
• Blind 10 — Tap, then stop at exactly 10 seconds. No clock.
• Target — Match a random time, shown for just a moment.
• Hold — Press and hold for exactly one second.
PASS-AND-PLAY MULTIPLAYER
Hand the phone around with 2–4 players. Pick an avatar, take your turn, and find out who really has the best internal clock on the end-of-match leaderboard.
TRACK YOUR PROGRESS
Per-mode bests, perfect rate, average drift down to the millisecond, daily streaks, and milestones — watch your timing sharpen over time.
• Clean, minimal design
• Satisfying sound and haptics (toggle anytime)
• Plays fully offline — no account, no sign-up
