Third-party reviews

Based on 247 buyer reviews from online shops.
Reviews last updated: June 2026 · How we calculate this

What we like about Misfit Ray

  • Sleek, minimalist design that looks like jewelry rather than a fitness tracker
  • Exceptional 6-month battery life using replaceable button cells, eliminating frequent charging
  • Water-resistant up to 50 meters, suitable for swimming and showering
  • Lightweight and comfortable for all-day and overnight wear
  • Automatic tracking for activity and sleep cycles
  • Discreet vibration alerts for incoming calls and texts

What we don't like about Misfit Ray

  • Lacks a digital display or clock, requiring a smartphone to check detailed progress
  • Activity and distance tracking can be less accurate than higher-end competitors
  • The companion app lacks some advanced features and third-party integrations (e.g., Strava)
  • Some users find the tubular aluminum design uncomfortable on certain wrist shapes
  • Basic sports band may feel thin or less durable compared to leather options
  • No built-in heart rate monitor

Verdict

The Misfit Ray is a minimalist, 8-gram, 12mm x 38mm cylindrical anodized aluminum tracker that utilizes a 3-axis accelerometer to track steps, calories, and sleep, offering 50-meter water resistance. Powered by replaceable batteries lasting up to 6 months, its key advantages include a versatile, jewelry-like design with interchangeable 8mm bands, always-on tracking, and a multicolor notification LED. Limitations include the lack of a screen or heart rate sensor, a finicky battery replacement process, and variable, sometimes inaccurate, tracking results.
