Pros

  • Effective blood oxygen measurement and sleep apnea event tracking—features many other rings lack

  • Supports both Android and iOS, with effective GPS tracking for locating the ring

Cons

  • The ring runs small; sizing up may still be tight and requires using the provided sizer for an accurate fit
  • Finish can scratch easily, especially on the inside surface
  • Sleep and step count accuracy are moderate; some users report higher step counts than other devices
  • Does not integrate with Apple Health or other native health apps, which may limit data sharing for Apple users
  • The sensor may not be as accurate as dedicated medical devices or highend competitors for sleep apnea detection
  • Lonerm durability and battery health concerns based on some user reports
  • The ring's thin profile may not be suitable for those who prefer a bulkier or more rugged device
  • Water resistance is good but not recommended for prolonged exposure or showering without removal
  • Some users find the tracking and monitoring features less reliable over extended use

Bottom Line

The RingConn Gen 2 stands out as a stylish, durable, and highly functional smart ring with sleep apnea monitoring and comprehensive health tracking—all without monthly fees. Its long battery life, comfort, and accurate measurements make it a solid choice for everyday health monitoring, especially if you want a discreet device that doubles as a fashion accessory. However, if you need ultra-precise medical-grade sleep apnea detection or seamless integration with Apple Health, you might want to explore dedicated sleep devices or competing rings like the Ultrahuman Ring Air, which offers longer battery life but may lack some of the fashionable appeal of the RingConn Gen 2.
