Store description excerpt
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. [Features] - Real-time seismograph waveform during measurement - Stability Score from 0 to 100 - Tremor Index in scientific units (g) - Hand Signature — your personal tremor pattern as a unique waveform - Personal best tracking - 9 languages: English, Korean, Japanese, Chinese, Spanish, French, German, Portuguese [Fun Ways to Use It] - Compare your score before and after coffee - Test dominant hand vs. non-dominant hand - Challenge friends to beat your score - Check how fatigue affects your stability Take the test now — and find out which category you fall into.
