Double Tap 10+
Read full descriptionHide full description
Ten seconds sounds easy. Landing on it is not. Tap once to start. Tap again when you believe 10.0000 seconds have passed. The gap between what you felt and what the clock recorded is your score, shown to four decimal places. RANKING FIRST The app opens on the leaderboard, not on the timer. You see the times you are chasing before you take your turn, and your own best runs are listed with the exact gap for each one. CLASSIC & DAILY Classic has one target: 10.0000 seconds. Daily hands everyone the same new target each day, drawn from over 200 real record times โ sprint splits, pit stops, free dives. Reproducing a duration you have never practised is a different skill entirely. VERSUS โ TWO PLAYERS, ONE IPHONE Put the phone on the table between you. The screen splits in two and the far half turns around, so both players read their own side. Tap independently, and whoever lands closer to 10 seconds takes the round. TRAINING Three preset targets to practise against, or any value from 3 to 60 seconds with Pro. YOUR TIMING A chart of your recent attempts, above and below the target line, with the one number that actually helps: whether you tend to stop early or late, and by how much. Correct the aim and the gap closes. PRECISION SCORING PERFECT โ within 100ms NEAR PIN โ within 500ms GOOD โ within 1 second MISS โ more than 1 second off ALSO INSIDE - Game Center leaderboards and achievements - Daily streak tracking - A result card you can share - No ads, and a round takes about fifteen seconds PRO (optional, one-time purchase) Your full saved history charted instead of the last ten attempts, plus consistency, hit rate and your early/late split, and any training target between 3 and 60 seconds. Everything else in the app is free. Trust the count in your head, then find out how wrong it was.
