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 preorder with a price of AU$739 in Australia
• It improves on battery life and heart-rate tracking, but its charging case steals the show
• Singapore and New Zealand availability and price TBC

Just a day after Ultrahuman’s CEO broke his silence on the new Oura-beating smart ring, it went up for preorder in most major markets for $479 / £419 / AU$739. That makes the new Ultrahuman Ring Pro a lot pricier than the $349 / £329 / AU$599 Ring Air, but the several improvements its brings — including the promised 15-day battery life — does seem to justify the premium.

Alongside the better battery comes improved sensors for better heart-rate tracking, especially during sleep, and an upgraded dual-core CPU that enables on-chip processing so the Ring Pro doesn’t need to rely on a paired phone. Ultrahuman also says that the CPU offers more accurate metrics thanks to machine learning.

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