Ultrahuman is expanding its health monitoring ecosystem with the launch of a new flagship smart ring and a “biointelligence AI” platform upgrade. The Ring Pro is Ultrahuman’s third-generation smart ring, and promises up to 15 days of battery life before needing to recharge, alongside 250 days of on-device health history storage. Those are some significant improvements compared to its predecessor, the 2023 Ring Air , which provides 4-6 days of battery life and several days of offline data
