Oura Ring 4 announced: sleeker design, updated sensors and redesigned app | Infinium-tech
The Ora Ring 4 is now official and it brings a number of improvements over the outgoing Gen 3 version from three years ago.
The Ora Ring 4 features a completely titanium exterior and interior except for the epoxy interior of its predecessor. The new device is 2.88 mm thick and weighs between 3.3 to 5.2 grams, depending on the ring size. It is also water resistant up to 100 meters.
The sensors inside are very thin at just 0.3mm compared to the Ring Gen 3’s 1.3mm and they don’t stick out. And while the sensors have shrunk, Ora is promising better accuracy.
The Ora claims a 120% improvement in blood oxygen (SpO2) measurements with a 30% increase in accuracy during sleep compared to the Ring Gen 3. The new ring also gets a more accurate heart rate sensor with less lag in day and night heart rate measurements. As well as improved breath delivery index (BDI) through its higher signal fidelity.
Aura has also addressed an inherent problem with smart rings by implementing an updated algorithm that accesses more signal paths from your finger at the optimal time.
The Ring 4 brings an updated automatic activity detection with support for over 40 modes and heart rate monitoring with heart rate zone breakdown. You also get sleep and stress tracking, as well as reproductive health trends. Automatic activity and stress tracking features are also coming to the older Ring Gen3.
The new Oura Ring still pairs via Bluetooth Low Energy to Android and iOS devices and comes with a redesigned Oura app offering a simpler interface and dynamic cards. The refreshed app will also work with the Oura Ring Gen3.
The Ring 4’s battery life is rated at up to 8 days on a single charge and charges via a new charging dock.
The Ora Ring comes in 4 Silver, Black, Brushed Silver, Stealth, Gold and Rose Gold colors and sizes 4-15. pricing begins $349/€399/£399 For Ring and you’ll also have to shell out an additional $/€/£5.99 per month ($/€/£69.99 per year) for the Ora subscription plan.
