While it doesn’t have built-in GPS, it pairs with your phone via Bluetooth and integrates with many fitness apps, which can supplement location tracking.

The Oura Ring 4 is a sleek, gold-colored smart ring designed to track a wide range of health metrics, including heart rate, sleep, activity, stress, and women's health data. It excels in sleep tracking and continuous monitoring thanks to its Smart Sensing technology, which adapts to you throughout the day and night. The ring is water resistant up to 100 meters, making it safe for swimming and everyday wear. Battery life is impressive, offering up to 8 days of use on a single charge, which means less frequent charging compared to many wrist-based trackers.

GPS functionality is supported but only through your phone’s GPS, not built directly into the ring, so location-based tracking depends on carrying your phone. Compatibility is broad, working with both Android and iOS devices via Bluetooth.
