Stop the countdown at exactly 00:00. Closer is better. ZEROED is a precision-timing game built around a single tap. A countdown falls - your job is to stop it the instant it hits zero. The tighter your tap, the higher you rank against players worldwide. Two modes, one mechanic: Solo Mode: is the practice mode. Pick any countdown from 1 to 60 seconds and train your timing in short, focused reps. Your bests, streaks, and a heatmap of every recent tap live on the Stats tab. Global Mode: is the always-running round, the whole world tapping at once. A new countdown starts, players from every country compete to stop it closest to zero, and the top scorer flies their country's flag at the top of the next round. Spectate any time. Jump in any time. No matchmaking. Designed for short, daily focus. Research on focused-attention training keeps finding the same thing: short, frequent sessions outperform longer occasional ones. ZEROED rounds are seconds long, on purpose. You don't need an hour. You need a habit. Features: • Solo practice with custom countdowns (1–60s) • Always-on global rounds — no matchmaking, just join • Country leaderboards — daily, weekly, and all-time • Lifetime stats: best delta, rounds played, sharp and perfect counts • Heatmap of recent taps — see your patterns • Apple Sign-In — no passwords, no email • Dark, minimal ZEROED Pro: Remove ads and unlock Solo's custom countdowns. • Lifetime — one-time purchase, yours forever • Monthly — 3-day free trial, then auto-renews Your purchase supports a small, independent developer.

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 • No ads How close can you get to a perfect second?
