Ultrahuman

Aina's titanium ring puts a small display and joystick on your finger, so you can say yes or no to AI tasks. Preorders are $399.

The ring built to get around Oura's patents is at Best Buy and Amazon. It costs $79 more than an Oura Ring 5 up front and needs no subscription.

Oura has filed a new patent suit in Texas over the Ultrahuman Ring Pro, the ring Ultrahuman reworked after losing the Ring Air in the US. The Ring Pro is still on sale while the case runs.

Ring Air and Ring Pro owners can now run a 60-second heart rhythm scan from the Ultrahuman app, built with FibriCheck. It's limited to supported markets in the UK, Europe, the Middle East and Asia-Pacific.

A second, smaller battery inside the ring body keeps the sensors running while the main module is off. Ultrahuman lodged the design in February 2025 and it published on August 20.

Ultrahuman released Jade to its whole user base as a software upgrade. The dual-core Ring Pro is what runs it on your finger.

Ultrahuman's new M2 Live tracks live glucose and over 100 blood markers in one place.
