HTC R02C Smart Ring Black 8
The HTC R02C is a smart ring sized for large fingers and finished in black. It tracks blood oxygen and heart rate for adults who want continuous health data without a wrist device. The 1.04 inch screen shows readings directly on the finger. Bluetooth connectivity sends data to a paired smartphone.
Thermals Noise Power
The ring has no fan or active cooling, so it runs silently and produces no noticeable heat during wear. Power comes from an internal battery charged by the supplied cable. Normal use lasts multiple days between charges. No external power supply is required.
Charging Cable Utility
The package includes a dedicated charging cable that plugs into the ring's proprietary connector. This cable is the only way to recharge the battery. No dock, adapter or additional accessories are bundled. The cable enables a full recharge in a single session.

Questions about this item
How do I install the HTC R02C smart ring and pair it with my smartphone?
Slide the ring onto your finger, then open Bluetooth settings on your phone and pair with the R02C. The step people miss is granting continuous background location and sensor permissions in the companion app so heart-rate and blood-oxygen data sync automatically.
What maintenance or replacement will the HTC R02C smart ring need over time?
Recharge using the supplied charging cable when the battery runs low. No user-replaceable parts are specified; if the sealed housing or sensors fail, the entire ring must be replaced.
What limit appears first during sustained all-day wear of the HTC R02C smart ring?
Battery endurance is the first constraint; continuous heart-rate and blood-oxygen monitoring will drain the cell faster than the waterproof seal or Bluetooth link degrades.
