Prior to the launching , Jason Russell , vice chairman of consumer software system product at Oura , talk to Digital Trends about the ring , giving us some interesting insights into what get it special .
The Oura Ring 4’s new design
“ We have improved the comfort for 24/7 wear , we ’ve expanded the sizing range , amend battery life story , and we have this incredible Modern sensing platform , ” Russell told Digital Trends , setting the view for the critical update .
The Oura Ring 4 is made of titanium , and this clock time , the metal extends to the underside of the ring , replacing the epoxy resin used for the former - generation models . The bean - like 1.3mm - high nubbin have been removed , and the sensors are practically flat at 0.3 mm high , increase overall comfort . The Oura Ring 4 weighs between 3.3 and 5.2 g , is 7.9 mm wide , and is 2.88 mm thick . It ’s now uncommitted in more size , ranging between size of it 4 and size 15 .
It ’s uncommitted in six different finishes : ash gray , grim , Stealth , gold , rise Au , and brush silver . The Stealth version has a ball field - comparable atomic number 6 ( DLC ) coating , while all the others have a physical vapour disposal ( PVD ) cake for toughness and scratch resistance . However , the undersurface of the ring is n’t cake , and titanium is hypoallergenic and cutis - friendly . The ring has 100 meters of water resistance and is suitable for swim . Oura claims the barrage fire will last for eight day , up from seven day for thethird - genesis Oura Ring , and it comes with its own charging pedestal , which should reload a flat electric battery amply in 80 minutes .
Upgraded sensors with better accuracy
You may be wondering how the recessed sensors have affected truth . Russell explained how accuracy has actually beenincreasedwith the new design .
“ We designed [ the bonce sensors ] five geezerhood ago because of their usefulness for truth , and we ’ve seen many smart ring makers leverage that same design . You also see some that do n’t utilize those dome , which really comes at the expense of truth . We ’re not uncoerced to sacrifice accuracy , and that ’s what ’s really singular about [ the Oura Ring 4 ] as we ’ve lour the domes , not just while defend accuracy , but really piss a Brobdingnagian leap forward using a rotatory Modern perception political platform squall Smart Sensing . ”
The Smart Sensing algorithm works with the sensors to gather information across 18 unlike pathways , up from the eight pathways on the Oura Ring Gen 3 . The algorithm dynamically adjusts to find the optimum path for increased truth . Oura ’s own subject area indicate the Smart Sensing platform will come back a 120 % improvement in blood oxygen sensing , a 15 % improvement in breathing disturbance accuracy , and few gap in heart rate transcription during the mean solar day and night . Russell told Digital Trends that the Oura Ring 4 has new light-emitting diode to go with the unexampled algorithm .
“ We really want [ the Oura Ring 4 ] to adapt to you , ” Russell continued . “ The ring can turn out 30 degrees in either direction , and we can still get a good sign . We address all varieties of finger’s breadth shape and size of it and get a good signal on them . The Ti interior is helpful for solace , but it ’s also helping for accuracy as it channels light in a more precise way , as it does n’t create light diffusion or absorb muse stray brightness that could occur with the epoxy textile and dome contour . ”
A redesigned Oura app
To go with the unexampled ring aim , Oura has also redesigned its associate app .
“ We have introduced 24 new features over the last 18 month , ” Russell reminded us . “ We ’re packing a lot in , and it can be overpowering . We have reorganize the app with that in mind , commit the direction on holistic health and connecting it with short - term metrics used for Readiness and nap activity and longer - term prosody like cardiovascular historic period . ”
There are three tabs along the bottom of the app : Today , vital organ , and My Health . Notably , shortcut tabs along the top of the Today sieve show familiar Readiness , Sleep , Activity , Heart Rate , Stress , and Menstrual Cycle wads , while the main section below shows current biostatistics and progression toward your end . The Vitals screen supply more in - depth data , while the My Health covert has long - condition wellness system of measurement such as Stress Resilience , Cardio Age , and ongoing tendency .
All features will be uncommitted for all Oura Ring members
There are some changes to survive feature , too . The Activity characteristic has gained machinelike heart charge per unit monitoring for 40 activities , up from just five before , complete with heart rate geographical zone tracking and V02 Max monitoring . The stress monitoring feature now include day-to-day movement and activities , plus manually added tag , for a more informatory overview of your day-after-day status . Tags can be added to a timeline , along with photo of meals , which the app will categorize mechanically for repast tracking .
Russell also mention that a rankness window feature will launch before long , and that all feature film will be available for all Oura Ring members . The new app will be made available to current Oura Ring owner over the coming week , and the previously iOS - onlyOura Labsfeature is now usable for Android owners too . Digital Trends also confirmed there is no change to the subscription price , which remains at $ 6 per month or $ 70 per year . The Oura Ring 4 come with one month ’s destitute access to the app .
Oura Ring 4 price and availability
The Oura Ring 4 starts at $ 349 and is available for preorder through Oura ’s on-line store today and will be quick for release on October 15 . It ’ll also be available through Amazon and in store include Best Buy , Target , and John Lewis in the U.K. Oura notes that the Oura Ring 3 will uphold to be uncommitted to buy until stock runs out , but we ’d advocate buying the latest version unless you find out it for a considerably lower price . Oura also has a newfangled sizing kit and recommends you use it even if you already own an Oura Ring , as it enunciate Oura Ring 4 sizes may be somewhat dissimilar .
Its arrival come after Samsung issue theGalaxy Ring , RingConn launched its updatedRingConn Gen 2 , and Circular made some changes to itsCircular Ring Slim . Oura has long been the bench mark for smart ring , and from what we can see at this stage , it has made meaning advancements in all area , from figure to accuracy , to help keep its position with the Oura Ring 4 .
