A 90-second hand check
Three quick things in front of your camera: tap your finger and thumb, open and close your hand, and touch your thumb to each fingertip. Everything stays on your device — no video is saved.
It's a rough check to share with your clinician — not a diagnosis.
Before the camera starts
You'll be asked to allow camera access. The video feed never leaves your browser — only per-frame finger angles are used to count taps and cycles.
- Sit at a desk or table with good lighting.
- Hold your hand 30–50 cm from the camera, palm facing you.
- If anything hurts, stop. Don't push for a higher score.
Confirm none of these are true right now:
- Sudden new severe pain or swelling
- Numbness, tingling, or color change in your hand
- Recent surgery without your surgical team's clearance to move
The hand check is observational only — open the libraries or orientation-only marketplace when you want structured education next.
