What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Lightweight, slim form factor that wears comfortably all day and night without intruding on daily activities
- Rich health-monitoring suite — Body Battery, sleep staging with sleep score, respiration rate, stress tracking, and SpO2 — drawn from Garmin's higher-end line
- Physical button is a clear improvement over the previous haptic button, giving tactile, reliable navigation
Reviewers push back
- Monochrome screen with low pixel density can look washed out in bright sunlight and makes notifications harder to read
- No built-in GPS — outdoor route and distance tracking requires carrying a paired phone
- Heart rate sensor takes several minutes to lock on accurately at the start of vigorous exercise, introducing early-workout lag
Reviewers broadly agree the Vivosmart 5 is a capable, comfortable fitness tracker with strong health-monitoring depth, held back by a monochrome screen, no built-in GPS, and a heart rate sensor that lags at workout onset.
Screen readability in daylight divided reviewers: CNET found it bright and usable in practice despite initial surprise at the monochrome choice, while The Wearableist sometimes needed several seconds to read it while running outdoors
