The Morning After: Oura's return to the smart ring fight

Oura's next-gen ring appears to be an upgrade in every way. It features a sleeker design, longer battery life and smarter sensors to offer deeper insights for wearers. Oura says Ring 4 has 18 signal pathways, up from eight in the Gen3, which is paired with its new Smart Sensing algorithm. New features include automatic heart rate and activity detection for up to 40 activities. All bar the Stealth is made of titanium. Oura Ring 4 is available to pre-order today, with shipping expected to begin on October 15, 2024.
