A public directory of patient wearables
Which wearables actually serve the patient?
Gadget reviews rank battery life and screens. WearScore instead scores health wearables on three things patients actually care about (explained just below), and does it openly for all 84 devices.

Draft
status per device
Every device gets three scores, 0–100:
Clinical value
Can you and a clinician trust the readings enough to act on them? FDA-cleared, validated devices score high; wellness gadgets stay low.
Empowerment value
Can you get your own data out and decide who sees it? Open APIs and free export score high; locked apps and paywalls score low.
Everyday value
Is it comfortable, affordable and practical enough to keep wearing? Fit, battery life, price and ease all count here.
Three numbers, on one map
Clinical power vs. patient control, sized by everyday fit
One dot per device. Left to right is its clinical value; bottom to top is its empowerment value, meaning how much control you have over the data. Bigger dots fit daily life better. The best devices sit toward the top-right. Use the filters below to show one class or category at a time, or flip to "Best only".
