W WearScoredoes this wearable serve the patient?
A public directory of patient wearables

Is this wearable clinically useful, and does it give the patient a real say?

Most reviews score battery and app polish. WearScore leads with two patient-first questions — clinical value (can a patient and clinician trust and act on it?) and empowerment value (does the patient own and control the data?) — then adds everyday value for how it fits into a life. Each device is also tagged by the health domains it covers.

Three numbers, on one map

Clinical power vs. patient control — sized by everyday fit

Each device is plotted by its clinical value (horizontal) and empowerment value (vertical). The lines cross at 60 — the point where a device becomes clinically meaningful, or genuinely patient-controlled. The size of each dot is its everyday value. Filter by class or by device category (Ring, Watch, In-ear…), and switch between every device and just the best — the "Best" view adapts to whichever category you've chosen.

Consumer flagship Recovery / wellness Clinical / medical-grade bubble size = everyday value
↗ Clinical & free
Trustworthy signal and patient control. The goal.
↘ Clinical but closed
Medically powerful, but the patient is the subject, not the owner.
↖ Open but thin
Respects your data, but measures little a clinician would treat.
↙ Thin & locked
Limited clinical signal and meaningful lock-in.
