About

Is there a spark between you two? Grab somebody and find out. This one needs two people. Lay the phone between you, put a thumb on the print at your end, and hold on for five seconds. The machine reads how you held it and gives you a Spark Score out of 100. IT IS NOT RANDOM Thumbsparks measures how together you land, how alike you press, and how steady you hold. Do it properly and you get a different number than if you fumble it. Your names set the starting point. The hold decides most of your score, and the app will show you exactly what it measured. ELEVEN WAYS IT CAN GO CRICKETS. LEFT ON READ. SIDE HUG. BUFFERING. MIXED SIGNALS. SLOW BURN. CAUGHT FEELINGS. BUTTERFLIES. FIREWORKS. THUMBSTRUCK. And, very rarely, COSMIC. Every tier has its own lines, and there are more than eighty of them. PAST READS Every pair's best reading is kept on the phone. Tap one to see the poster again. THUMBSPARKS EXTREME A one-time unlock, not a subscription. Add a third point of contact: hold hands, touch foreheads, link pinkies, back to back, knees touching, or whatever you can talk each other into. Scores swing fifty percent further in both directions, so the best readings you will ever get are Extreme ones. So are the worst. Somebody has to ask. That is the feature. NO ACCOUNTS. NO INTERNET. No sign-up. No ads. No tracking. No analytics. The app contains no network code at all, so nothing you do in it can leave your phone. For entertainment only. Thumbsparks does not read fingerprints, cannot tell whether you are touching, and cannot predict anything. It is a game.

What's New in Thumbsparks

1.1

September 10, 2026

Thumbsparks now tells you what it is for. Clearer from the first screen. How to Play says outright that this takes two people, and the home screen asks the question the game answers. How your Spark Score works is now one tap from the home screen, and it is written in plain English instead of small print. Thumbsparks Extreme: your dare gets its own space, plus a re-roll button for when neither of you will do that one. Also a redrawn mark, a louder Spark Score on the poster, and a lot less text everywhere.
