Shake Meter vs Bubble Level

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.

Bubble Level - Calibrated turns your iPhone into a practical, accurate bubble level for everyday measuring, alignment, and leveling. Most phones do not sit perfectly flat. Cases, raised camera lens bumps, uneven backs, and different phone shapes can all affect level readings. This tool is designed with proper calibration so you can account for real-world phone surfaces and get more reliable measurements. Use it to check whether a surface is level, measure angles, align objects, or quickly verify slope. It is useful for hanging shelves, setting up furniture, aligning picture frames, checking tables, DIY projects, and quick household measurements. Features: - Bubble level for horizontal and vertical surfaces - Proper calibration for phones with cases and camera bumps - Helps account for uneven phone backs and raised lens areas - Angle and slope measurement - Clean, easy-to-read display - Fast launch for quick checks - Useful for home projects, DIY, furniture setup, construction, and alignment A phone level should work with the phone you actually use — case, camera bump, and all.
