Stop Timer Button Challenge
Precision Reaction Timer Game
Only for iPhone
Free
iPhone
Challenge your friends! Now with Arcade: round after round on three lives, with the window closing as you go. Plus a daily run everyone plays the same version of.
A big red button and a stopwatch you cannot see.
Tap to start it. Tap again when you believe the target time has passed. The clock stays hidden while it runs, so there is nothing to read and nothing to count. Only your own sense of how long a second is. Can you finish all of the missions?
Then it tells you exactly how close you were.
FIVE WAYS TO PLAY
• Classic — pick a target and chase it, or let the app pick one for you
• Arcade — round after round on three lives, with the window closing as you go and a streak multiplier that makes the round you are on worth more than the last
• Daily run — five targets, the same for everyone, scored out of 100
• Missions — thirty levels that get tighter, longer and less forgiving
• Party — pass the phone around, closest to the target takes the round
BUILT TO BE FAIR
Your time is measured from the moment your finger touches the glass, not from when the app gets around to noticing.
Nothing on screen moves while the clock runs. Anything that repeats on a fixed interval is something you could count, and counting would defeat the whole thing.
Play to one, two or three decimals. The grading follows your choice.
MAKE IT YOURS
Eight button designs and eight displays, or build your own: shape, colours, size, labels. Use one of your own photos as the face of the button. Tune the haptics and the sounds to taste, or switch them off.
KEEP TRACK
Every attempt is logged. Personal bests announce themselves. Statistics show where you land, and whether you tend to stop early or late.
NOTHING LEAVES YOUR PHONE
No account. No advertising. No analytics. No tracking. The app has no network connection at all, so there is nothing for it to send even if it wanted to.
