I wear the Ultrahuman Ring Air every day, which makes me very excited to try the much-improved Ring Pro.

• Ultrahuman has released the highly anticipated Ring Pro for pre-order priced at AU$739 in Australia
• It improves battery life and heart rate tracking, but its charging case steals the show
• Availability and pricing in Singapore and New Zealand TBD

Just a day after Ultrahuman’s CEO broke his silence on the new Oura-beating smart ring, it has gone up for pre-order in most major markets for $479 / £419 / AU$739. That makes the new Ultrahuman Ring Pro significantly more expensive than the $349 / £329 / AU$599 Ring Air, but the many improvements it brings – including the promised 15-day battery life – seem to justify the premium.

Along with the better battery, improved sensors for better heart rate tracking, especially while sleeping, and an improved dual-core processor that allows for on-chip processing so the Ring Pro doesn’t need to rely on a paired phone. Ultrahuman also claims that the processor offers more accurate metrics thanks to machine learning.

It’s the new charging case that steals the show in my opinion. Not only does it extend the battery life of the smart ring up to 45 days, but it also has an LED light that gives you a clear visual indication of how much battery it still has.
