Have you already pre-ordered the new Oura ring? The Pre-Order Updates section of our site is the place to check for new updates, important dates and exclusive sneak peeks. We’ll be publishing updates approximately every two weeks. In our third Pre-Order Update we answer the questions you’ve sent us – from the simple yet important to the unexpected.
There are two Oura rings: the first Oura ring that was launched in 2015 that’s no longer being sold. Then there’s the new Oura ring (announced in 2017). We call them the first Oura ring and the new Oura ring.
The first Oura ring was launched in 2015. We’re sharing the stories of people who have used the first Oura ring.
While not technically a question, we love the first Oura ring too! You don’t have to update to the new Oura ring if you don’t want to. The new app will work with the first Oura ring but some features will be unavailable and not every new feature update will be compatible with the first Oura ring. Please note that you can only use one ring per account, so if you decide to wear both the new ring and the first Oura ring you’ll basically need two phones and two accounts.
No. The rings are shipped on a first-come-first-served basis. If you were one of the first to pre-order, you’ll be one of the first to receive the new ring. The first rings will start shipping out in April. They will be shipped in batches during the spring and early summer.
We’ll send you more information related specifically to your order closer to the start of shipments. The new rings will be shipped out in batches and we can’t at this time estimate when exactly your ring will arrive. We’d rather wait a bit and make sure than set you up for a disappointment.
Please contact our customer care for changes at firstname.lastname@example.org.
At this stage we charge orders at the time of the order.
Sure. Here’s our return policy.
Not yet. We’ll send everyone an email that takes them to a page in which they can choose their size. We’ll send out these emails in batches, so if your friend gets the email before you do, it’s OK, yours is coming too. With the email you’ll also get more information and video instructions on how to choose the right size for you.
The Oura Sizing Kit is not the only option to find your ring size. You can visit a jewelry store, print 3D sizers, use your old Oura ring as a reference or order a sizing kit. You cannot order the sizing kit yet. The upcoming sizing email will have more information on how you can find out your size and how you can let us know which size you choose.
Yes and no. The size of your fingers changes throughout the day. Usually, your fingers are slightly swollen during the night and right after you wake up. When your fingers are cold, they’re usually the thinnest they get. When trying on the sizing rings, it’s best to warm up your hands. You can take a walk around the block, take the stairs or do some jumping jacks (remember to warm up for your warm up) and then try the sizing rings. It’s usually better to choose the bigger size if you’re having trouble choosing between two sizes. The ring should feel comfortable right after you wake up.
When the ring fits you perfectly, the chances of you wearing it continuously for years to come are the greatest. A good fit ensures you get the benefits of uninterrupted long-term data.
The smallest Oura ring size is US6. If it’s too big for you and you really want to wear the Oura ring, you could try adding some padding (inside and top) or wearing it on your thumb. We generally don’t recommend padding though because it adds a layer of friction to the otherwise smooth inner surface. Also, let us know if there’s a need for smaller sizes and we’ll promise to look into it. However, the size range for the foreseeable future is US6 to US13.
Drop us a line and let us know. We’ll look into extending the size range if there’s enough demand for the big sizes. However, the size range for the foreseeable future is US6 to US13.
You can wear it on any finger, on either hand. We usually recommend either the index, middle or ring finger.
Nope. The Oura ring is meant to be worn on a finger. That said, we’ve actually tried wearing it on a toe with some luck, but it’s not really designed for that.
No. The app is free and available for iOS and Android.
Yes. We’re continuously improving the Oura app and the ring firmware. The new ring opens up many new opportunities and we’ll be building and expanding the new features based on your feedback.
Not at first. There are plans to introduce more languages but right now it’s only English.
Many of the new features will be available also with the first Oura ring. On-demand resting heart rate is one of the new features that very likely won’t be compatible with the first Oura ring.
The on-demand resting heart rate and heart rate variability feature is meant to be used while meditating or during breathing exercises. The ring will also track restful moments, such as naps. You can start and stop tracking with the app. For the duration of the recording, the ring will send your heart rate and heart rate variability to the app, in which you can see it in real-time. The feature cannot be used during exercising. You also cannot cheat the system by leaving the recording on for the day.
Yes. It’s water resistant to 100 m. You can swim, shower and go snorkelling with the Oura ring. During our tests we haven’t been able to get water inside any of the rings but we’ll keep pushing the limits.
Yes, the ring can withstand hot temperatures.
Yes. Just keep your finger from freezing. The ring on it will be just fine.
We don’t recommend doing exercises in which the ring rubs against metal or other hard surfaces. There is also the risk of discomfort or hurting yourself if you wear a ring while lifting heavy weights.
No, not easily. The titanium with diamond-like coating (DLC) is resistant to scratches, but it has its limitations. And yes, the Oura ring can scratch softer metals like silver or gold. We don’t recommend wearing two rings next to each other.
Yes. And yes.
If you’re concerned about EMF, you can turn on the Airplane Mode in the new Oura ring. The ring collects data even if it’s in Airplane Mode but it won’t transmit anything. More info here.
We don’t recommend doing combat sports, martial arts or other impact sports with any ring.
Not really. There is no way to manually erase specific data from the app.
For sure. The Oura ring designs are unisex. Choose whichever ring catches your fancy. Many have reported getting compliments after they’ve started using the ring.
You can wear the Oura ring only at night if you choose. Alternatively, you can practise a smooth pocket move in which you remove the ring from your finger if you spot a potential mate. That said, the ring has turned out to be a great conversation starter. We’ve actually witnessed some wedding proposals with the Oura ring so it might actually help you too.
Technically yes. You’ll need two phones and two accounts, however.
Yes, it can be cut from it’s thinnest point, palm side of the finger with standard ring cutters.
The rings look different. The functionality is the same.
For images of the differences, check out this article.
You have to decide for yourself.
Yes, we wouldn’t have it any other way.
Nope. The chargers for the new Oura ring are size-specific and the charger and the ring need to make an accurate fit so that charging works optimally. Every Oura ring is shipped with a charger though.
To ensure optimal battery performance, instead of partial charging, charge the ring until the battery is full whenever possible.
No. You’ll have to charge the Oura ring with the Oura ring charger. A flat charging pad won’t work with the Oura ring.
Not as such. Only the new Oura ring charger can charge the Oura ring. However, if you phone charger has a USB-C connector going into your phone, it can equally well go to the Oura charger as well. Alternatively you can plug the Oura USB-C cable into your phone charger if there’s a place for it.
Yes. We’ll make the chargers available at ouraring.com as an accessory.
Sure, if that cable is a standard USB-C cable suitable for charging. We recommend using high quality cables to be safe.
Anything with a standard USB-A outlet, typically your laptop or a separate USB charger or dock.
Yes. The charger comes with a USB-A to USB-C cable. You can connect the charger to your laptop, for example.
Sleep Analysis, both the “in bed” and “asleep” time; “in bed” can contain more than one “asleep” period when Oura detects awake time while in bedHeart Rate, in this case the lowest resting heart rate during sleep.
Active Energy, i.e. calories burned in physical activity in addition to the Resting Energy (also known as idle burn or basal metabolic rate, BMR).
Weight, if you edit it in the app
Height, if you edit it in the app
Yes. The Clue app and Precise.ly.
Yes. Your privacy is a top concern for us. Your data is always handled securely.
This functionality is coming but not right at the shipment start.
Yes. The Oura Cloud API makes it easy to access the data the ring gathers and calculates. To use Oura Cloud API, you need an Oura account and you have to register your application. You can read the documentation here.
The new Oura app update will be published at the same time as the rings ship out. Sync your first Oura ring to the app. Your data will be stored in the Oura Cloud. Take the new ring into use with the updated Oura app. Your data will be synced from the Oura Cloud to the updated app. None of your historical data will be lost.
