Ahead of MWC 2026, health tech company Ultrahuman unveils its Ring PRO
It's reportedly packing a best-in-class 15 days of battery life per charge, along with a clamshell case doubling as a smart alarm
It's also launching its AI 'biointelligence' called Jade, which Ultrahuman CEO Mohit Kumar believes could even order healthy food via Door Dash in the near future, based on the user's needs
Most of the best smart rings last for a little under a week between charges, but that's all about to change. Ultrahuman Ring Pro (styled as PRO) has just been revealed ahead of the MWC 2026 tech show next
The Ultrahuman Ring PRO is going to be most notable for offering double the battery life of its competitors, at up to 15 days between charges.
In an interview with Tech Radar, Ultrahuman CEO Mohit Kumar said, "Rings are incredibly small devices, really small batteries. The batteries are typically like 50 to 20 times smaller compared to a wrist device. So to get something to last for 15 days took us months of engineering effort".

An updated version of the Luna Ring with a slimmer design, better battery and useful tools – but nothing game-changing in a crowded smart ring market.
The Ring PRO also boasts a redesigned heart rate sensor array, four colors – Bionic Gold, Space Silver, Aster Black, and Raw Titanium – and a smart clamshell-style charging case (image below), which also doubles as a smart alarm clock, as you can leave it on your bedside table. With the case, Kumar says you'll be able to get two months out of the smart ring.

Ultrahuman is also launching Jade, an AI LLM health advisor service in the Ultrahuman app. Health advisory LLMs are common in the fitness app space, but Ultrahuman seems to be doing things a bit differently. Kumar tells me it's a purpose-built model rather than something based on Chat GPT or Claude, due to potential privacy issues.
"It could lead to inaccurate insights as well, because you might not be getting the entire context," said Kumar. "So first thing we wanted to ensure was that the data stays on secure servers. It doesn't go out, and it's completely deeply integrated with our own secure, compliant servers."
Jade is apparently more action-oriented than Q&A-based, and Kumar has hinted at its powerful decision-making, which will be in future updates. Kumar said, "In the future, Jade bio diligence would be able to take action on your behalf, even autonomously. It can understand your sleep, your recovery, your movement, your nutrition through your CGM data, and potentially can even place a food order for you, like from Door Dash, in the background.
"So it will understand what kind of food you should be eating at what time to make sure that you have enough time to digest the food before you go to sleep. So this autonomous nature of Jade is something that is new in the industry.
"We are taking it to the next level by making it anonymous and very, very action-oriented."
It certainly sounds powerful – although I'm not sure my wallet would appreciate an LLM ordering Door Dash on my behalf. Stay tuned, as we'll get hands-on with the Ultrahuman Ring PRO in the future.
