Hold your phone still for 5 seconds and see your Stability Score. From Neurosurgeon to Seismic Event — where do your hands rank?
Hold your phone still for 5 seconds — find out how steady your hands really are.
Shake Meter uses your phone's accelerometer to capture every micro-movement and turn it into a Stability Score from 0 to 100.
[How It Works]
- Hold the phone firmly with both hands
- A 3-second countdown begins automatically
- Stay as still as possible for 5 seconds
- The accelerometer captures movements at 50 samples per second
- Your Stability Score and Tremor Index appear instantly
[What Your Score Means]
Neurosurgeon (90-100): Your hands are steadier than a robotic arm. You could thread a needle in a hurricane.
Stone Cold (75-89): Ice-cold precision. Your hands make calculated, deliberate decisions.
Pre-Coffee Mode (55-74): Solid stability, even before the morning caffeine kicks in.
Vibration Enthusiast (35-54): Your hands hum like a phone on silent. Something exciting going on?
Human Maraca (15-34): Not shaking — percussing. You have a rhythm all your own.
Seismic Event (0-14): Scientists have registered your tremor on the Richter scale.
