HTC COLMI R02 Smart Ring Rose Gold 8#

The HTC COLMI R02 is a new smart ring designed for men and women who want continuous health insights without a recurring subscription. It tracks heart rate, blood oxygen levels and sleep duration through built-in sensors and connects to a smartphone via Bluetooth. The ring is supplied in size 8 with a rose gold finish.

Charging Case And Subscription-Free App

A compact charging case is included so the ring can be recharged away from a wall outlet. The companion app unlocks all tracking features immediately and requires no monthly fee, keeping long-term ownership costs at zero. Battery life varies between two and five days depending on the selected monitoring mode.

Sizing Kit Recommended For Fit

The manufacturer advises buyers to purchase a separate sizing kit or consult the size chart before ordering to ensure the correct finger fit. Choosing the wrong size is the most common reason for returns, so verifying measurements first avoids unnecessary exchanges.

Which mode gives the shortest battery life when the ring is worn continuously?

Enhanced Mode monitors heart rate in real time throughout the day and lasts 2-3 days before the ring must be placed back in its charging case.

How warm or noisy does the ring get during all-day wear?

The ring has no fan or moving parts and weighs 100 grams, so it runs silently and stays at skin temperature during continuous use.
