BIEMHA VR11 Smart Ring Black 12 23 Day Battery

BIEMHA VR11 Smart Ring Black

The BIEMHA VR11 is a screenless activity tracker worn on the finger. It targets adults who want continuous health insights without a wristband or subscription fees. The ring uses Bluetooth to sync data with a companion app on Android devices. Its IP68 waterproof rating allows wear during swimming and showering.

Practical limits of Bluetooth sync

Heart rate is sampled automatically every 30 minutes while the ring is worn. Real-time streaming is not supported; data transfers when the ring connects to the paired phone. The 4.0 sensor array handles heart rate, blood pressure and sleep duration, but does not measure blood oxygen or skin temperature. No display means all readings must be reviewed in the app.

Check finger size and Android version before

Supplier size 12 corresponds to a 1.32 inch inner diameter; measure your finger circumference against the maker's chart to avoid fit issues. The ring requires an Android phone with Bluetooth for pairing; iOS compatibility is not confirmed in the specifications. A lithium-ion cell provides up to 23 days of use per charge cycle.
