Grids Gear

Accurate sizing is crucial for comfort and sensor performance. We provide a detailed printable size guide on our product pages. We recommend measuring your finger at the end of the day when fingers are at their largest. The rings are available in multiple standard sizes (e.g., US #8 to #13). If you are between sizes, we suggest choosing the larger one for comfort.

The smart ring is designed for all-day wear with minimal charging. A single full charge (which takes about 1 hour using the provided magnetic cable) delivers an average of 5-7 days of battery life, depending on usage of features like gesture control and heart rate monitoring.
