Oura Ring is now slimmer, slicker and more powerful – News | GadFit

November 30, 2017

Back in February this year, I found myself curiously attracted to the sleep metrics churned out by a ring I wear to bed every night. The Oura ring’s sleep algorithm was the first, and currently still the only, wearable to be independently validated by Stanford Research Institute.

Unfortunately the oversized ring was impractical for all day wear and short battery life that runs only 2-3 nights worth of sleep recording were some of its prominent shortcomings.

I’m happy to hear that the company is intending to release an improved version of their sleep tracking ring; one that has taken into consideration feedback from their initial wearable attempt at scientific sleep recording.

The new Oura ring is slimmer and 10 times more powerful than the previous edition. As it is, I was already impressed with the first generation Oura ring’s prowess – the company went on to add HRV tracking as a firmware update.

The new ring is also the first consumer-available wearable that offers guidance on how to improve your circadian alignment – optimal bedtimes, sleep improving habits along with personalised activity guidance will be provided. Sounds impressive doesn’t it?

Kinnunen, the Chief Scientist at Oura. “What makes this possible is our database of over a
million individual nights. We can utilize machine-learning to uncover previously hidden trends and patterns to serve individual people and help them understand themselves better.”
