Which wearable should your program buy?
Every device below works with NavixPulse. They differ in which signals they provide, how they wear, and what they cost — the chips on each card show exactly what feeds the algorithm. Checkout happens on Amazon; we don't handle payment.
Simple bands
Vivosmart 5
The lightest way in: a slim band people forget they're wearing, feeding the core overnight signals.
- · Comfortable enough for true 24/7 wear
- · Simple for people who don't want a smartwatch
- · Most affordable full-signal option
- · No HRV or skin temperature
- · Small monochrome screen
Charge 6
A familiar band with nightly HRV and temperature variation — note that some analytics sit behind Fitbit Premium.
HRV: nightly · Stress: EDA-based score, not continuous · Skin temp: nightly variation · Readiness: requires Fitbit Premium
- · Nightly HRV and temp variation at a band price
- · Familiar to many wearers
- · Some metrics need a Fitbit Premium subscription
- · Stress model differs from Garmin's

- · Invisible under clothing; no screen to fixate on
- · Monthly membership on top of purchase
- · Sizing kit adds an onboarding step
