Description by Emre ALTUN (from the App Store)

ZeroIn is a stopwatch reflex game: the clock runs and you stop it exactly on target. Sounds easy — until the timer disappears.

300+ LEVELS
• Visible clock, vibration beats, fully blind timing and countdowns
• Vanishing digits that show for two seconds, then fade away
• Math targets: if it's 3 × 2, stop the clock at 6.00
• Time estimation: feel 7.35 seconds without seeing a single digit

TEST YOUR REACTION TIME
Every stop is measured in milliseconds. Earn up to three stars, chase gold (under 10 ms) and unlock new START buttons with your points.

ONLINE REFLEX DUELS
• Real-time tables with up to 12 players
• Invite friends with a link and rematch in seconds
• Climb the global ranking and the monthly season

MONTHLY SEASONS
The top three of every season win a champion frame and a full month of ZeroIn Pro.

BOOSTERS
Second Chance, Slow-Mo, Reveal Timer and Second Buzz help you through the toughest levels.

DAILY REWARDS
Come back every day for lives, boosters and bonus stars — and save your streak if you miss a day.

ZeroIn Pro: no ads, unlimited lives, double star points and the Black Hole button.
