The Oura Ring Product Overview

Oura RingWhen Kari Kivelä, Petteri Lahtela, and Hannu Kinnunen first pitched their smart ring through Kickstarter in 2015, they made it clear their product wasn’t just a gimmicky piece of tech. The Oura Ring was ultimately designed to be a wellness computer, but small and personal enough for anyone to use. The original goal for the Oura startup was $100,000. Oura’s creators ultimately raised $651,803 for their project, allowing them to bring their smart rings to the world. In 2016, Oura won the 2016 CES Innovation Award.

The Oura Ring collects highly accurate data about the body by measuring your blood temperature, blood volume pulse, and detecting both the amplitude and intensity of how your body moves. These measurements tell the ring when you’re asleep or awake and if you’re active or inactive. It collects initially this information over a period of days and sets a personal baseline from which to help you decide how well you sleep or if you’re meeting fitness goals.

Everything You Need to Know About the Oura Ring Sleep Tracker

Product Ratings

Category Rating What Users Are Saying
Ease of Use Good The ring and app work well at providing customers with useful information about sleep and fitness. There’s a lot of data, and some of it might be a bit more technical than some users are used to, but by reading the FAQs, it should help you understand how to read the collected insights. Once understood, the process of using the ring and app becomes straight-forward.
Sleep Tracking Accuracy Good Most customers felt the sleep tracking was very accurate and useful. Tracking might be impacted by connection issues.
Sleep Tracking Support Fair There were many complaints regarding difficulty syncing the ring to the app and the app not collecting data as a result of poor syncing. Oura seems to be working to improve support over a period of updates and by interacting directly with customers who’ve expressed concern.
Additional Features Fair Customers feel the Oura shines as a sleep tracker more so than as a fitness tracker. It is good at motivating less active customers by encouraging them to move after long periods of inactivity.
Price Good The ring provides a lot of useful information. Though premiumly-priced, the Oura competes with much larger fitness trackers by collecting as much information, but in a smaller form, which makes it easier to wear all day without interfering with your day-to-day life.
Battery Life Very Good Oura’s creators worked to improve the battery so it functions for longer, allowing more active customers to get the most out of the ring without having to charge it as frequently. When tracking highly active customers, the battery life can weaken over time.

Sleep Tracking

Oura’s overall primary function is to help you understand your sleep habits and find ways to improve. It does this by regularly tracking your sleep and restful behaviors. The smart ring begins by collecting data to create a baseline from which you can start to make improvements.

For example, the Oura Ring records your sleep patterns, keeping track of when you go to bed and wake up. The app examines your existing sleep schedule and how your body recovers from daily strains or a tough workout. It might determine after collecting so much data that you’re not getting to bed at an optimal time for sleep and recovery. What Oura will then do is recommend a sleep window that better suits your daily rhythms.

This sleep tracker doesn’t just tell you when you slept for how long; Oura collects information about your nightly sleep cycle. It tracks time spent in REM and deep sleep cycles as well as moments you woke up during the night. The app displays your daily, weekly, and monthly sleep quality, letting you measure improvements or issues over a long period of time and learn where you should make adjustments.

Perhaps even most useful, the app allows you to add notes and tags, allowing you to recall certain issues that might interfere with your day-to-day ability to get proper rest and recovery. Through monitoring and note-taking, Oura lets you both understand your individual sleep needs and be more accountable about how you track issues and make changes.

Fitness Tracking and Additional Features

The Oura Ring helps you keep track of your fitness level in two ways. It monitors your resting heart rate during sleep and rest by keeping track of your Blood Pulse Volume (PBV) to create a baseline measurement. Once that’s established, it makes note of elevations in your resting heart rate to determine if you’ve adequately recovered from heightened physical activities.

It also keeps track of how active you are during the day, counting each step you take and making note of long periods of inactivity. Oura uses this data to help you set daily fitness targets, which when combined with quality sleep, allows you to live a healthier lifestyle.


After you’ve placed your order, you’ll receive an email. In the email, click to confirm the ring size you’d like to order.

If you aren’t sure of your ring size, Oura provides a sizing kit, which you can send for when placing your ring order. You cannot order a sizing kit separately; its only available when you’ve purchased your Oura ring. It’s also possible to download 3D printing files for creating your own sizing kit. The file format is .stl.

You can wear the smart ring sleep tracker on any finger. The company does recommend wearing it on your index, middle, or ring fingers for fit and comfort. It’s important to make sure the ring is comfortable. For accuracy in sizing, you might want to measure your fingers in the morning, as they’re slightly bigger than they are later in the day.

If you’re between sizes, Oura recommends that you size up for assured comfort. For larger knuckles, choose the smallest size that slides easily over the knuckles. As of now, Oura is available in 8 sizes, ranging from US6 to US13. Although custom options aren’t available, by using the sizing kit, you can be sure that the ring you order is as close to custom-fitting as possible.


The Oura Ring is a top-tier wellness computer in a very small package. Because of this, the ring is on the more expensive end of sleep trackers. Oura is confident that its sleek design, combined with the seamless way in which the ring monitors and works to improve your overall health, justifies the premium pricing.

Battery Life

Oura’s creators worked hard to improve the battery life of their smart ring. Initially, the Oura Ring Sleep Tracker held its charge for two or three days. Now, with the second version of the Oura Ring, the product enjoys a battery that lasts up to a full week.

When you order the Oura Ring, it comes with a ring box that also functions as a charger. To charge, the ring must be placed so that the gold charging pads face the charging pins on the charger. The battery takes anywhere from 30 to 60 minutes to fully charge. While it’s charging, you’ll see a pulsating dim white light. When charging is complete, the light stop pulsating and glows with a solid white light.

By activating battery notifications in the Oura app, you’ll know when the ring’s battery needs to be charged and when charging is complete.


The newest version of the Oura Ring is compatible with most mobile devices running iOS 11.0 or later and Android 6.0 or later. The original Oura Ring Sleep Tracker works with iOS 10.0 or Android 5.0 and later.

Additional Considerations for the Oura Ring Fitness and Sleep Tracker

Care and Maintenance

The Oura Ring is made from titanium and a diamond-like carbon coating, allowing it to stand up to everyday wear and tear. It contains a non-allergenic, non-metallic inner molding. Additionally, the ring is water-resistant up to approx. 328 feet.

The Oura ring’s customer-centric design means that it will keep up with the most active of customers. That said, you should still take care to avoid direct contact with metal, ceramic, or stone surfaces as scuffing may occur.

It’s possible to wear the Oura Ring to the gym, though it’s not recommended to wear the ring while lifting weights. It might be possible to prevent scuffing during weight lifting by wearing gloves.

Shipping & Delivery

The Oura brand is based in Finland, so payments made by credit card might be subject to a foreign transaction. The company offers free shipping every day of the year.

Rings are available to be shipped to customers all over the world. For customers in Europe and the United States, Oura covers the cost of duties and taxes so that you’re only paying for the product itself. For international customers not placing orders from the United States or Europe, Oura will cover carriage to their location, however, the customers themselves are responsible costs related to import clearance.

Return Policy and Warranty

Customers can return their Oura purchases for any reason within 30 days from the date of purchase, provided the ring isn’t damaged and is still fully functional. To return your product, contact Oura’s Customer Care at [email protected] or [email protected] to get a Return Merchandise Authorization (RMA) number and the return address.

Oura suggests sending the ring back in its original packaging, but if that’s not available, make sure the smart ring and accompanying accessories are carefully packed to avoid damage during shipping. Make sure the RMA number is clearly visible on the outside of the package and that you ship to the address provided. Shipping and handling charges are non-refundable.
