Parkinson Detector

Parkinson Checker is a simple, at-home tremor and motor self-screening tool. Draw a spiral, do a quick finger-tapping test, then see an easy summary and trends over time. It’s for awareness and education—not for diagnosis or treatment.
How it works
Spiral drawing test – trace an on-screen spiral to capture hand tremor.
Finger-tapping test – alternate taps for 15 seconds to gauge speed, rhythm, and consistency.
Instant summary – view a simple overall score plus details (e.g., taps/sec, variability, freezes, alternation errors).
History – compare past runs to notice changes.
No sign-in – open the app and start—fast and private.
Why people use it
Establish a baseline and watch trends over days or weeks
