Everything about the ring is sleek and sophisticated. Before you purchase the ring, the brand sends you a sizing kit with plastic rings of all sizes, which we thought was super helpful as you do need to get the right fit for best results. When the ring is on, it looks just like a standard men’s wedding band, and you can choose from gold, silver, black or stealth (a very dark silver) finish. The ring itself comes packed in a slim white box, complete with ring, USB-C charging cable and cradle.
The ring is quite pretty, but it is much thicker than our normal rings, which took a little getting used to. We found the sensors in the inside of the ring to be virtually unnoticeable, and they didn’t affect comfort or wearability. We tested it in the shower, running, gardening and cooking, and it certainly didn’t feel uncomfortable or obstructive, and did not slip off or discolour.
TrackingThe accuracy of the sleep and readiness scores are impressive – although after a night of tossing and turning, no one needs an app to tell them they had a bad sleep. The data that is collected overnight and updates shortly after waking up on the app homepage in easily digestible scores. This was nice to check each morning, and the fact that it tracked your progress over time made us feel like we were in a sleep competition with ourselves. We found this element of gamification made us more committed to wearing the ring.
The ring is designed to be worn throughout the day, and we wore ours on the index finger mostly. We found that while it fit well at night on the index finger, during the day it was sometimes a bit too snug, so we swapped it to the ring finger.
InsightsThe insights are effectively what you’re paying for. Oura recommends wearing the ring for two weeks to establish baseline data that can then be used to monitor changes. The insights will tell you how well you slept, your readiness for the day, and track activity to determine if you’re staying active enough. The results certainly correlated with our personal energy levels. When readiness scores were high, we felt more alert and could concentrate more at work. When the score was low, we felt tired and unproductive.
We liked the sleep insights, which take a deep dive into everything including REM sleep (important in re-energising mind and body), deep sleep (the restorative kind that helps muscles repair, immune system refresh and brain flush out toxins) and latency (how long it took you to fall asleep). The recommended bedtime was also a bit like that best friend who’s always looking out for you – and it did give us an extra push to put our phone down and go to sleep.
Another feature is the period tracker and predictor. At the time of reviewing, you could manually add the dates of your last period in the app, and then tap the button to indicate when your next period starts. Once the ring gets two months of data, it will be able to predict your next cycle using the calendar method, however in the future it will use body temperature changes to make predictions. And for those tracking fertility, this may also be a game changer as the temperature sensors can track your basal body temperature changes as small as 0.1C, indicating when you’re ovulating.
AppThe Oura app is available for Apple and Android, however we did find that, at the time of reviewing, the latest version of the app was not compatible with our older model Android phone.
The daytime heart rate was fun to check at certain points throughout the day – such as during a stressful meeting or after a gym class. Why do we need this? Oura claims taking time to relax during the day can help you recover from physical and mental strain, and improve your ability to learn and retain information. But in practice, unless you’re an athlete, or need to know your heart rate for work purposes, this feels like a bit of a gimmick.
The social share feature also seemed a bit redundant, as even in the world of social oversharing, it’s unlikely we would feel the need to share our sleep score on the gram. There will be a new section in the app available later in the year with mediation and sleep videos and breathwork sessions – we think this could be great and make the membership fee more attractive, as the best stand-alone mediation apps like Headspace can be expensive. Hopefully these elements also provide more education around how to improve your sleep and activity, as we definitely feel the whole point behind the ring is not the data itself, but what we do with that data.
Connectivity and battery lifeThe ring lasted about six days of constant wear before it needed to be charged. Charging only took about two hours, and it slid easily onto the small charging dock. Plus, we could wear it comfortably in the shower, going for a run, typing and cooking. It connected quickly to Bluetooth, but, at the time of reviewing, the latest version of the app was not compatible with our older model Android phone.
PriceThe ring is priced at around £225 (US$299). But with the gen 3 ring, comes a new membership fee of around £4 (US$5.99) per month on top of that to access all of your data in the app. Existing Oura rings users who upgraded by 29 November 2022 received a free lifetime subscription, and any new users will get a six month’s free trial before they need to start paying. Basic users who don’t subscribe will only see three activity trackers – readiness, sleep, activity. Without being able to see all the new features in the app at the time of testing (as explained above), it’s hard to know if this is good value, but it will probably put off some potential users.
