Milavan TK20 Smart Health Ring, New Black, Sleep & Activity Tracking, IP68
Product description
For adults who want to keep tabs on daily wellness and workouts in a ring format, the Milavan TK20 brings activity tracking, sleep monitoring, and a New Black finish together in one wearable.
Its sensor tracks heart rate, stress, and other wellness metrics every 30 minutes, while automatic sleep monitoring follows sleep stages and awake periods. The companion app is free to use, with no subscription fees.
With support for iOS and Android, the ring syncs tracked activity to a smartphone. Its 7 mm width and polished inner surface are designed for comfortable daily wear and sports use.
Key features
The TK20 tracks heart rate, stress, and other daily wellness metrics automatically, giving you information to review in the app as part of your routine. These readings are for reference and are not intended for medical use. For sleep, its 24-hour automatic monitoring records deep sleep, light sleep, REM stages, and awake periods, offering a fuller view of rest than a tracker that only records at set times.
For workouts, the ring supports 187 sports modes, including running, walking, boxing, ball sports, and water and ice sports. Exercise data syncs to the app, where you can review your activity. GPS is provided via a smartphone, so location tracking uses the connected phone. The ring connects by Bluetooth and works with Android and iOS devices.
The ring has an IP68 waterproof rating and a listed water-resistance depth of 50 meters. Its 7 mm width, micro-matte finish, and polished inner surface support everyday wear and movement, while the included charging case and cable support recharging. The listed average battery life is 3 days, and charging time is 1 hour. The free app adds a way to review tracking without a subscription.
Size & fit
Choose the ring size using the size chart and measure your finger circumference before ordering. A well-matched fit helps keep the ring comfortable through everyday wear and exercise. The polished inner surface is designed for comfort, and the 7 mm width gives the ring a defined profile without changing its ring-style form factor.
Everyday use
Wear the TK20 to follow activity throughout the day, then use the app to review the data it records. During a run or walk, select the relevant sport mode to log workout information, after exercise, turn the mode off to help avoid excessive battery drain. For location-based activity information, the ring relies on GPS via the connected smartphone.
At night, automatic sleep monitoring follows sleep stages and awake periods, so sleep tracking does not require you to start a session manually. Compared with a wrist-worn tracker, this ring offers a screen-free wearable format: it has no display, and tracked information is viewed in the app. That makes it a practical fit for people who prefer ring-style wear and want wellness and workout records in one place.
