## Long description

Powerton Smart Ring PRO in black is a wearable health tracker designed to monitor heart rate, measure stress levels and track sleep patterns. Sized 12, the compact ring houses optical and motion sensors that collect continuous physiological data and synchronize with a companion mobile app. The device records resting and active heart-rate trends, stress indicators derived from heart-rate variability, and sleep stages to support daily health tracking and recovery assessment.
Advantages
The Powerton Smart Ring PRO provides continuous monitoring in a discreet, lightweight form factor that fits finger wear. Its integrated sensors enable round‑the‑clock heart-rate and stress measurements without requiring a chest strap. Sleep tracking captures duration and stages to help identify changes in sleep quality. Data synchronization with the companion app allows users to review trends and export or compare measurements over time.
Suitable for

How to use
Place the Powerton Smart Ring PRO on the finger that provides the most comfortable and stable fit (size 12). Ensure the ring sits snugly but not too tight so sensors maintain skin contact. Install and open the companion app on a compatible smartphone, pair the ring via the app’s setup flow and allow required permissions for data collection and synchronization. Wear the ring continuously for the most complete heart-rate, stress and sleep records; charge the ring as needed following the manufacturer’s charging procedure.
Usage recommendations
For reliable heart-rate and sleep measurements, wear the ring consistently during rest and sleep periods, keep the sensor area clean and dry, and ensure the companion app is regularly synchronized. If precise clinical measurements are required, consult a healthcare professional and use this device as a supplemental monitoring tool rather than a diagnostic instrument.
