Colmi RING 2 Lubricated Ring Size 9 - Black

COLMI RING 2 combines a compact stainless-steel design with functions for monitoring health, sleep and daily activity. Sensors track heart rate, HRV, blood oxygen levels, stress and body temperature, with the collected measurements available through the Q Ring app. Built-in AI functions can analyse the recorded health, sleep and activity data and provide additional information based on the measurements.

Sleep tracking operates automatically and covers both nighttime sleep and daytime naps. RING 2 records periods of wakefulness as well as light, deep and REM sleep, while also measuring sleep onset time, sleep efficiency and nighttime awakenings.

For exercise, the ring supports sports modes including walking, running, cycling and swimming. During activities, it can record heart rate, steps, distance, calories burned and workout duration. Menstrual cycle tracking is also available through the app.

The Q Ring app includes additional social functions. Friends and Family Ranking allows users to compare step counts, while Space of Love provides features for couples, including anniversary records, relationship certificates, Love Reminder and Walking in Sync. Gesture control can also be used for selected functions such as photos, videos and games.

RING 2 is designed for continuous use during the day and while sleeping. Its 5 ATM water resistance allows use during activities such as hand washing and swimming. The battery provides approximately 3–5 days of use, while the included 200 mAh charging case with USB-C provides a convenient way to recharge the ring.
