Practice

Rough day

Routines and challenges record automatically once the camera is set up — Sandbox is free play and doesn't record unless you press Start session. Affected side is the hand you're recovering — both-sides plans and your report use it; camera scores is just which hand is being measured right now. If the wrong hand lights up green, toggle Swap L/R. Calibrate my range captures what YOUR hand can do today so goals fit you. Calm turns off confetti/animation; Cheer-on reads your expression to encourage you — it stays on your device. “I’m done” ends a session anytime; “Skip ›” moves past a routine step.

Reach Standard Assessment

Eight timed items — hand, fingers, wrist, elbow and shoulder — the same protocol every time, about five minutes. Practice adapts to you; the assessment never does, so change you see here over the weeks is real. Do it rested, every week or two; ending early keeps the items you finished. Your camera setup is checked the whole way; items with shaky tracking are marked and never scored.

Calibrating your personal range first (Practice tab) makes the assessment fit your hand. The camera must be on.

Replay file…

Download CSV exports every recorded session's trials, one row per attempt, plus a second small file saying what each column means. Alt-click the same button for JSON (dictionary built in; includes the per-frame raw + conditioned series); Alt+Shift-click for the per-frame series as CSV; Shift-click for the raw half-second trace of the current session. Recording saves the landmark stream only (positions of 21 hand points — never video) so a session can be replayed and studied. Replay runs a saved recording through the live instrument.

Progress

The report assembles your practice, trends and latest assessment into a printable page for your care team — generated on this device; nothing is uploaded.

Your care team

Everything here runs on this device, and nothing leaves it on its own. The loop with your care team travels with you: a clinician writes a plan on the prescription page and hands you a code — paste it under Have a plan code from your coach? in Practice. Going the other way, Print report and Copy summary for your coach above turn your practice into something to bring to an appointment.

Care-team members: the coach view is the paired dashboard, and it needs the hosted deployment — on a local clone there is no account service, so plans and summaries travel as codes and printouts instead.
