Reading a clock face at a glance is a skill you've had since childhood – On the Dot turns it into a race. Find the dial that matches the target time, tap it before the timer empties, and keep your streak alive as the pace quickens. A quick, minimal one-thumb game that's as casual or as competitive as your reflexes make it.
Tap the clock that matches and you score – your streak ticks up by one and a fresh tray snaps in. Tap the wrong dial and the run ends on the spot. The whole game is one-thumb tapping, with nothing between you and the next match.
A timer bar starts draining under the target the moment each round begins. Read the hour hand, check the minute hand, rule out the decoys – and the instant you tap the right dial, a bright rising tone and a tick of haptic feedback confirm the match before the next one appears.
Easy to learn, satisfying to do fast – that's the mix that turns one quick run into a whole session.
Let the timer empty before you find the match and you lose one of three lives – the board nudges and a fresh tray slides in. Tap the wrong dial, though, and there are no second chances: the run ends immediately. Look before you leap.
The longer your streak runs, the less time each round gives you, and the decoy clocks creep to within a minute or two of the target. A quick glance is no longer enough – you have to actually read the hands apart.
When a run ends you get a clean read-out: how many clocks you matched this run, your best streak so far, and your average time per match – the number to beat next time.
A simple loop with just enough teeth: every run asks how long your eyes can keep up.
Switch between two hand-tuned themes in Settings: After dark, all charcoal trays and off-white hands with a glowing mint accent on the timer; and Daylight, a Swiss-minimal palette of cool light trays, black hands and a single yellow accent. On first launch the app simply follows your phone's light or dark setting.
Before you even start, the home screen carries a live analog clock ticking your device's actual current time – a quiet reminder of what the whole game is really about.
Every blip, match chime and game-over tone is generated on the fly with the Web Audio API – there are no audio samples bundled at all – alongside subtle haptic feedback. Prefer silence? A single switch in Settings mutes it.
The moment the app loses focus or slips into the background, the game pauses itself and waits on a Resume screen, so an incoming call or a glance at another app never costs you a streak.
None of it is flashy, and that's the point – it's a clean, quiet game that simply feels right to pick up.

It's a time-matching reflex game. A target time appears at the top of the screen and nine analog clocks sit in a 3×3 tray below; you find the one whose hands show that exact time and tap it before the timer bar empties. Match clocks in a row to build your streak, lose a life each time the timer runs out, and end the run instantly if you tap the wrong dial.
There's no difficulty menu – the challenge ramps up on its own. The longer your streak runs, the shorter each round's timer becomes and the closer the decoy clocks creep to the target time, until their hands are only a minute or two apart. You set the pace by how long you can survive.
