A calm, satisfying tap you won't want to put down. One number, going up — that's the whole game, and somehow it isn't. A study in the integer. The Tap Experiment is an exploration of the oldest, quietest human compulsion: the urge to turn a 1 into a 2. To make the smaller thing into the slightly larger thing. To see what happens next. There is no enemy. No timer. No level. There is a number, and there is you, and there is the space between them. Tap to fidget, to focus, to unwind — for as long as you like. — FEATURES — · One tap. One number. Nothing in your way. · Haptics tuned to the count. · Optional music. Optional sound. Optional dark mode. · Game Center leaderboards, for those who must compare. Tap. Breathe. Watch it grow.
