Stop the clock
right on target.
ZeroIn is a reflex game built on one perfect moment. The clock runs — your only job is to stop it exactly on target. The closer you land, the more stars you earn. Master it solo, then race friends online.
Everything is about the perfect moment
Precision scoring
Land within 5%, 3% or 1% of the target and earn one, two or three stars. Every millisecond counts.
Four solo modes
Custom target, the viral 10 seconds, a 5-round sprint, and the 1–10 second ladder to sharpen your instinct.
Blind mode
The numbers vanish while the clock runs. No display, no hints — just you and your inner sense of time.
Vibration assist
Feel the rhythm with a buzz at your chosen interval and a mini pulse at the target moment.
Online rooms
Create or join a room and race up to 12 players in real time. The host sets the rounds and target range — everyone starts together.
Friends & leaderboards
Add friends by username, send game invites, and climb both the global and friends leaderboards.
Three steps, endless "one more try"
Start the clock
Pick a mode and a target, then tap to send the timer running.
Feel the time
Count it in your head or let vibration guide you. In blind mode, trust your gut.
Stop dead on it
Nail the target for three stars, then push your streak higher — or challenge friends.
Can you feel the time?
