Milavan TK20 Smart Health Ring, New Gold, Sleep and Activity Tracking

Automatic heart rate and stress tracking gives the Milavan TK20 a practical role in everyday wellness routines. The slim smart ring records metrics throughout the day and syncs them to its free app.

Its 24-hour sleep monitoring tracks deep, light, and REM sleep, along with awake periods. That gives you a more detailed view of overnight patterns in one wearable.

With a New Gold finish, a 7 mm width, and support for iOS and Android, the ring brings fitness and wellness tracking into a compact, easy-to-wear format. It also works with a free app and has no subscription fees.

Everyday use

The TK20 automatically tracks heart rate, stress, and other daily wellness metrics every 30 minutes. You can review the information in the app and use it as a reference for your routine, these metrics are not intended for medical use. Bluetooth connects the ring to a compatible smartphone or tablet, while GPS relies on the connected smartphone rather than a built-in GPS receiver.

For sleep, automatic monitoring runs around the clock and records deep sleep, light sleep, REM stages, and awake periods. That makes the ring useful for keeping wellness and sleep information in the same wearable instead of relying on a wrist-based tracker. Its polished inner surface and micro-matte exterior are designed for comfortable daily wear, with a finish intended to help resist fingerprints and scratches.

Where it shines

The ring supports 187 sports modes, including running, walking, boxing, ball games, and water and ice sports. Activate a sport mode to record workout data, then sync the results to the app. For activities such as running, cycling, golf, or yoga, this lets you review exercise information alongside your everyday tracking. Turn off a sport mode after your workout to help prevent unnecessary battery drain.

Its waterproof design is listed for depths up to 50 meters, making it suited to water-based activities as well as daily wear. Before ordering, use the size chart and measure your finger circumference so you can choose a comfortable fit. A ring that fits well is especially important for a wearable intended to stay on through daily activities and sleep.

What matters most

The Milavan TK20 pairs a 5.0 sensor with an upgraded AB2026B3 chip. The product features describe the chip as supporting faster response and lower power use, while the sensor handles automatic wellness tracking. The ring’s 7 mm width and New Gold finish give it a distinct, jewelry-style look without changing its role as a fitness tracker.

Battery life is listed at an average of three days, with a one-hour charging time. The ring uses Bluetooth to sync with Android and iOS devices, and the companion app is free with no subscription fee. In the box, the listed contents are the smart ring, charging case, charging cable, and user manual.

Is it worth it?

The TK20 brings sleep monitoring, wellness metrics, and sports tracking together in a ring format, with app access on both Android and iOS. It suits adults who want an alternative to a wrist-worn fitness tracker and prefer to review activity and sleep data through a smartphone app. For a daily routine that includes workouts, overnight tracking, and water activities, its 187 modes, 24-hour sleep monitoring, and 50-meter waterproof rating make it a practical wearable to consider.
