The Tap Experiment

“An experiment in the integer.”

A minimal toy app exploring what happens between you, your finger, and a number on screen. Just a single counter, the small surprise of watching it tick, and a quiet leaderboard of everyone else doing the same.

What it is

A single counter, taken seriously.

The Tap Experiment is a one-screen study of the most basic interaction we have with a phone: tap a thing, see a number change. The app strips everything else away and leaves you alone with the counter. Keep a daily streak going, pass the odd milestone, and see where your total sits on the worldwide leaderboard through Game Center on iPhone or Google Play Games on Android. It’s free with a small banner ad, and a one-off Remove Ads purchase takes it away for good.
