Ultrahuman on Friday unveiled a new smart ring with longer battery life and a redesigned form factor, as the Bengaluru-based wearable maker seeks to revive its U.S. business that was disrupted last year by a patent dispute with rival Oura.

The Ring Pro, Ultrahuman’s third-generation smart ring, offers up to 15 days of battery life — compared with four to six days on the Ring Air — and is priced at $479. It will be available for pre-orders globally, excluding the U.S., with shipments beginning in March.

Ultrahuman’s U.S. business was disrupted in October 2025 after the U.S. International Trade Commission — a federal agency that handles trade disputes — ruled in Oura’s favor in a patent dispute.
