Which wearables work best for a treatment program?

Simple bands like the Garmin Vivosmart line are the lightest way in — affordable, week-long batteries, and people forget they're wearing them. Fitbit bands add nightly HRV at a band price, full watches add richer metrics, and the Oura ring suits people who won't wear a wrist device. The right choice depends on which signals your program wants, battery tolerance, and budget — not on any one brand.

For programs buying devices in volume, the practical criteria are: which signals the device actually reports (sleep stages, resting heart rate, HRV, respiration, stress), how long the battery lasts (charging is the number-one adherence killer), how it wears (a slim band beats a smartwatch for people who don't want one more screen), and total cost.

NavixPulse maintains a free public device guide at navixpulse.com/devices with exactly this comparison: every supported device, the precise signals it feeds, honest pros and cons, and plain purchase links that earn the project nothing — no affiliate incentives, so the recommendations stay honest.

Programs don't need to standardize on one device. Because every signal is read against the wearer's own baseline, a mixed fleet — bands for most, rings for some — works fine; the comparisons are within-person, never across devices.
