Milavan R11 Smart Ring, Gold Size 13, Sleep and Activity Tracking
Product description
At a slim 2 mm profile, the Milavan R11 is a Gold size 13 smart ring for everyday wellness and activity tracking. It records heart rate, sleep patterns, and workout data in the companion app. Want to check your daily activity without wearing a wrist-based tracker? The ring format keeps those features in a discreet wearable.
Everyday use

Wear the ring to track heart rate automatically every 30 minutes, then review daily readings in the app for general reference. Sleep tracking records deep and light sleep, REM, and awake periods, giving you a view of your overnight patterns alongside daytime activity. These readings are for reference and are not intended for medical use.


For exercise, select a sport mode in the app and view activity details such as workout duration, steps, heart rate, speed, calories burned, and distance. Supported activities include running, cycling, jump rope, walking, hiking, yoga, dancing, and golf. The ring also supports remote photo control, while its care mode lets you share activity data with others. Bluetooth connects it to a compatible smartphone, and the app does not require a subscription to access its features.

What stands out
The R11 brings sleep, heart-rate, and activity tracking together in a ring rather than a wrist-worn device. Its polished inner surface and slim profile are designed for comfortable all-day wear and use during most sports activities. That makes it a practical format for people who want daily tracking in a small wearable, with app-based details available after a workout.

The activity features cover both exercise sessions and everyday movement, while sleep tracking adds an overnight view. Rather than relying on a separate tracker for each routine, you can review these categories through the ring’s app. Its stainless steel and resin construction, Gold finish, and size 13 designation also make it easy to identify the specific style and fit when choosing a ring.
When it makes sense
It makes sense if you want a ring-style tracker for everyday activity, sleep, and selected sports, and prefer checking your records in an app. Before ordering, use the size chart and measure your finger circumference to help choose a comfortable fit. Pair the ring with an Android 5.0+ or iOS 9.0 smartphone, then use Bluetooth and the app to review heart-rate readings, sleep stages, and workout information. With its Gold finish, size 13 fit, and subscription-free app access, the R11 suits people looking for a wearable that brings routine wellness tracking into a discreet ring format.
