The OURA ring is one of the most advanced wearable devices to date as of March 2019. It is essentially a ring that acts as a sleep tracker and a health monitor. Among others, the OURA ring helps with tracking various stages of sleep, resting heart rate, and heart rate variability. Additionally, it acts as a general activity and health tracker.
I have ordered the Oura ring on 30 November 2018 (silver Heritage), and a sizing kit. The sizing kit was shipped on the 1st of December, and I received it on the 6th of December. The same day I chose my ring size with the help of a kit, and the ring was delivered by 28th of January.
For now, I have had Oura ring for 1.5 months, and I can say that it is now hard to imagine life without the ring. Every morning, the ring shows you your overall “readiness score”, which takes a value between 0 and 100, depending on your health measurements tracked by the ring, previous day activity, and sleep, and so on. The most surprising thing for me was that sometimes in the morning I don’t feel great and rested at all, while the ring shows the opposite – that my readiness is high. Interestingly enough, more than 90% of the time the ring is right. The opposite is also true – sometimes I feel quite good and rested in the morning, while the Oura app shows that my readiness is not that high, so I should take it easy, and somewhere mid-day I start suddenly feeling more tired than usual. Overall, it is very useful to know, how your body feels in the mornings to be better prepared for the day.
1. Opening the box
The ring comes in a beautiful box with a premium feeling to it.
Inside the box, you have the ring itself, a wireless charger (USB to USB-C wire, the charging pad, and no A/C adapter), the ring itself, the user manual and a warranty.
That is how the ring looks on a charging pad:
The OURA ring comes in two main shapes: “heritage” and “balance”. Check out the photos below:

Both heritage and balance rings come in 3 main colors: silver, black, stealth, and rose. The silver ring color can also be chosen with a hint of luxury: diamonds.
The ring itself is made of titanium with scratch-resistant DLC (diamond-like carbon) coating and is water resistant up to 100 m.
The features of Oura ring can be summarized by the measurements and KPIs provided by the Oura app. The ring is quite easy to sync with an app.
The app has 4 main screens:
3.1 Features: home
The home screen currently looks like this on the latest iOS and Oura health app versions (as of 23. March 2019):
The home screen shows a summary: your readiness score (0-100), a summary of your previous night’s sleep and a resting heart rate, a summary of your daily activities, and some suggestions at the bottom of the screen (e.g. “the bedtime approaching, time to relax” and similar).
The readiness score and automatic suggestions that the app gives you is a very powerful feature. Knowing, how you feel, how your body responds to activities, and the quality of your sleep, the app is able to give you actionable insights into how to optimize your regime and activities in order for you to feel better. Super cool!
3.2 Features: readiness
The second screen in Oura app shows your readiness, and looks like this:
The readiness screen shows you the history of your readiness scores and resting heart rate at the top. Lower, you can see some of the health metrics that the ring is monitoring: resting heart rate, heart rate variability, body temperature, and respiratory rate (frequency of breathing).
Below, the app shows you some of the measurements that contribute to your overall readiness, the “readiness contributors”:
- Previous night sleep
- Sleep balance
- Previous day activity
- Activity balance
- Body temperature
- Resting heart rate
- Recovery index
This seems, like a pretty decent stack. Besides taking into account the measurements from the previous day, the app also takes into account the “balance” metrics: sleep balance and activity balance, which represent longer-term trends in your regime and health. If you have a messy sleep schedule, then after 2 nights of good sleep the chance is that you still will not feel very good.
3.4 Features: sleep
The third screen in Oura app shows the sleep data. You can see the screenshot below:
The top of the screen is very similar to the “readiness screen”, which shows some of the summary indicators of the sleep. I scrolled it down a bit to show some of the “sleep contributors” that the Oura ring helps to track. Overall, it seems to be a pretty good combination of sleep measurements to be able to track your sleep quality long-term. Personally, I find the measure “restfulness” to be very useful. Sometimes, it is not obvious at all, whether you are well
A little lower than these metrics, you can also see the graphs of your sleep stages at night, and when you have been waking up. It is not 100% precise, but nonetheless, it is definitely good enough to be useful.
Below the graph with the sleep stages, you can see, how your resting heart rate has been changing through the night, the average resting heart rate and the minimum.
3.4 Features: activity
The last screen in the app shows the activity summary and statistics.
The activity screen looks similar to the other screens; the structure is the same. One nice feature of the app is the suggestion to “Stretch your legs”, an activity alert, which is sent when you have been inactive for some time. It is, of course, optional and you can opt-out if you want to.
The activity tracking in the Oura app is manual. You have to choose the activity from the list, choose the activity intensity and timing. Would be cool, if Oura was integrated with some of the activity trackers, like Garmin or Endomondo.
4. Battery life
The battery charging is quick and painless – the charger is wireless, and charging does not take long. On my subjective experience, it took me between 30 and 50 minutes to charge the ring fully.
Typically, the battery lasts 3-4 days, which also depends on your usage of the ring.
The battery level is displayed on the app’s home screen in the top right corner.
Another very handy feature is that the app sends you an alert, when you need to charge the ring, so you don’t have to remember to charge it. Pretty cool.
Oura ring in-app support
In the Oura app, there is an option to send a support ticket straight from the app in a chat format, and receive a reply also in the app. I have had a few questions about the app, its features and planned releases, and I always received nice replies form their support staff.
Overall, I highly recommend Oura ring. My experience with is very positive: I was always able to know the status of the ring production and delivery tracking, the ring provides some very useful features for biohacking enthusiasts like me, which would certainly be very useful for those of you, who really want to know more about your health and to be able to improve it proactively.
I give the Oura ring 10/10.
