The Oura Ring Gen 4 Size 11 in Stealth Matte Black is a sleek and advanced activity tracker designed for both indoor and outdoor use. Made from durable titanium, this ring provides accurate heart rate monitoring and has a battery life of up to 7 days. Compatible with iOS and Android operating systems, it offers measurements in both decimal and imperial systems, making it a versatile tool for unisex adults interested in tracking their running and jogging activities. With its black colour and English language settings, the Oura Ring Gen 4 is a stylish and functional accessory for anyone looking to improve their fitness. I just bought the ring on May 15, 2025 but have chosen not to keep it so it is very new!!
