Steady Hand Tremor Test
Hold your phone perfectly still — do you have surgeon hands? Score and share.
Hold your phone perfectly still
10 seconds. No resting it on a table — that's cheating. Do you have surgeon hands?
iPhone will ask permission — tap “Allow”.
This shines on a phone 📱
Your device has no motion sensor — but you can still test your mouse hand: keep the cursor frozen in the arena for 10s.
Open this page on your phone for the real tremor test.
Motion access blocked
No problem — you can test your mouse hand instead, or re-enable Motion & Orientation access in your browser settings.
Get ready
100% private — motion is measured on your device and never leaves your browser.
Not a medical test. Just a fun way to see how steady your hands really are. ✨
