Frequently Asked Questions
Do these rings have built-in GPS?
No — these smart rings are GPS-lite. They estimate distance and rely on your phone’s GPS or internal motion sensors for route and distance estimates, so they’re great for heart-rate and sleep recovery but not for standalone route mapping.
How accurate is heart-rate and HRV data?
The rings provide continuous optical heart-rate, SpO2 and HRV tracking suitable for trend monitoring and recovery decisions. For clinical-grade accuracy or cycling power-based training, a chest strap or dedicated medical device is still recommended.
Will I need a subscription to use the app?
No — these FKGZJF models advertise lifetime app access with no subscription fees, so you can view daily, weekly and monthly metrics without recurring charges.
