A share card generates after every run, made to look right in iMessage, Instagram, TikTok, Discord, and X.
Open the app, hold still for 20 seconds, see your score. No tutorial, no onboarding, nothing to learn.
Even a calm, healthy hand never actually stops moving. A natural tremor at around 8 to 12 times per second runs in the background of everyone's nervous system, whether you notice it or not. Holding a phone truly still for 20 straight seconds means fighting a signal your body never turns off, which is exactly why a high score is a real, measurable feat and not a coin flip.
It's also 20 seconds of doing nothing else. No feed to check, no notification to answer, nothing to tap. Short, deliberate pauses like that are one of the simplest ways to interrupt a stressful moment, and most people's day never has one on purpose. Pause just gives it a score.

No. Guest play is entirely local to your device - your best score and run history stay on your phone. Sign in with Apple or Google only if you want to appear on the leaderboard or sync progress across devices.
From 0.00 to 100.00, based on how still you hold the phone over a 20-second run. The algorithm rewards consistency over luck, and large sudden movements cost far more than tiny corrections. Most players score in the 80s and 90s; a perfect 100 essentially never happens.
Guest play never leaves your device. If you sign in, only what's needed to run the leaderboard and sync your progress is stored. See the Privacy Policy for the full details.
