Steady Hands

Steady Hands helps users run short on-device hand tremor self-checks and compare local results over time. Choose left or right hand, hold the phone still, start a timed check, and review recent scores in the local history screen.
The app uses device motion sensor data during a test to estimate movement. Results are stored locally on the device and can be cleared by the user. Steady Hands is not a medical device and does not provide medical advice, diagnosis, or treatment.
