Oura Ring 5

Oura Ring 5Price, Where to Buy & Whether to Wait

Last updated

Oura pioneered the smart ring category in 2015 and remains the company every other smart ring is compared against. Ring 5 is its biggest hardware redesign since Ring 2, shrinking the device by 40%, improving sensor accuracy, and introducing Blood Pressure Signals. Finger-based sensing generally provides stronger PPG signals than wrist-worn devices, helping explain why smart rings excel at sleep and recovery tracking.

Quick answers

All FAQs

Quick answers

Oura Ring vs Samsung Galaxy Ring vs Ultrahuman (which is best)?
Oura leads on sleep tracking accuracy and clinical credibility. Samsung Galaxy Ring wins on no subscription fee and Samsung Health integration. Ultrahuman wins on metabolic health with built-in glucose monitoring options. Oura is the right choice if sleep and HRV are your primary metrics.
Which size Oura Ring should I get?
Order the Ring 5 Sizing Kit before buying, even if you owned a previous Oura Ring. Ring 5 is about 40% smaller than Ring 4 and its interior fits differently, so your Ring 4 size may not transfer.
Does Oura Ring work without a subscription?
A membership costs $5.99 a month or $69.99 a year, and your first month is free. Without one, Oura's more detailed health insights are locked.

No dedicated AFib or irregular-rhythm feature is documented for Oura Ring 5.

Oura has not published a dedicated AFib or irregular-rhythm detection feature for Ring 5. This is based on independent 2026 reviews because Oura's own medical-condition pages discuss arrhythmias but do not publish a simple AFib feature list.

Oura Ring 5

No new model soon

We don't expect a newer model soon, so there's no reason to wait for one.

Older model costs less

Oura Ring 4 is $50 cheaper. You'd give up things like ring battery rating.

Full price everywhere

None of the stores we check has it on sale yet.

What would make this a buy?

A drop to around $364 or less would automatically make this a Buy, as long as a replacement is not close.

How we read this
  • We read store prices every day and keep every read. The price shown is the newest read from the retailer named.
  • A read older than 36 hours is never shown as the current price. It reads "last seen" and carries no buy link.
  • “30-day low” is the lowest of our own reads for this product in the last 30 days, not a retailer’s claim. We print the number of reads beside it, and we say nothing about a low until a product has a week of reads.
  • “Lowest known”, where it appears, is older price history from published reports and imports. It is shown only when it is lower than the 30-day low, and it is not counted as reads.
  • The verdict is worked out from the price, the history and whether a newer model is coming. It never depends on who pays us.

Frequently asked questions

Questions about Oura Ring 5

Top questions

Oura Ring vs Samsung Galaxy Ring vs Ultrahuman (which is best)?
Oura leads on sleep tracking accuracy and clinical credibility. Samsung Galaxy Ring wins on no subscription fee and Samsung Health integration. Ultrahuman wins on metabolic health with built-in glucose monitoring options. Oura is the right choice if sleep and HRV are your primary metrics.
Which size Oura Ring should I get?
Order the Ring 5 Sizing Kit before buying, even if you owned a previous Oura Ring. Ring 5 is about 40% smaller than Ring 4 and its interior fits differently, so your Ring 4 size may not transfer.
Does Oura Ring work without a subscription?
A membership costs $5.99 a month or $69.99 a year, and your first month is free. Without one, Oura's more detailed health insights are locked.
Does the Oura Ring 5 come with a charger?
It comes with a size-specific standard charger and a USB-C cable. Oura's in-the-box list does not include a power adapter.
How accurate is Oura Ring sleep tracking?
Oura publishes 79% agreement with polysomnography for sleep staging, against roughly 60 to 65% for typical wrist wearables. Other trackers have peer-reviewed validation too; Oura's claim is accuracy, not exclusivity.
Does Oura Ring work with Apple Health and Google Fit?
Apple Health, yes. Google Fit, no: Oura says its Google Fit integration is no longer available. On Android, Oura syncs through Health Connect instead.
What is the Oura Ring 5 battery life?
6 to 9 days depending on ring size and settings. Smaller rings have less battery capacity, and larger sizes reach the 9-day end of the range.
Is there water resistance on Oura Ring 5?
Yes, up to 100 meters (328 feet), IP68 rated for water and dust. It's built to withstand saunas, ice baths and everyday water exposure.
Do you need a new sizing kit for the Oura Ring 5?
Yes, even if you own a Ring 4. Oura says Ring 5's sizing runs 6 to 13, while Ring 4 ran 4 to 15, and the interior fits differently, so choose the free sizing kit at checkout and confirm your size before the real ring ships.
What actually changed between the Oura Ring 4 and Ring 5?
It is smaller: about 40% less volume, thinner and lighter, with sizes 6 to 13 instead of the Ring 4's 4 to 15. Oura says the Ring 5 lasts a little longer on a charge than the Ring 4. Most of the new software features are also rolling out to the Ring 4 and Ring 3. A charging case is available separately for a full day of charge in about 10 minutes.
Why is my Oura ring glowing red?
Depends where the red is. A faint red glow through the ring while you wear it, especially at night, is the blood oxygen sensor working normally with red and infrared light. Red circles in the app just mean low battery. A blinking red light on the charging dock usually points to a problem with the dock itself, and contacting support is a reasonable next step.
How tight should an Oura ring be?
Snug, not tight. It should sit securely at the base of your finger and come off with a bit of soap and water, but not slide off on its own. Make a fist, and if you see a gap between the ring and your finger, size down. If it will not turn at all, it is too tight. Stuck between two sizes, size down, partly because the plastic sizer drags more than the finished ring does.
How does the Oura ring measure stress?
It infers it rather than measuring it. Daytime Stress is built from heart rate, heart rate variability, motion and average body temperature, compared against your own baseline. Nothing in the ring detects cortisol or reads your mood, and it skips workouts and sleep. A high reading means your body is working hard, which is not the same as feeling stressed.
Why won't my Oura ring connect?
Work through it in order. Update the phone and app, put the ring on the charger and check the light, keep the phone plugged in since power saving interferes with Bluetooth, and keep the two close together. If that fails, forget the device and re-pair. On Android, also check that Bluetooth and Nearby/location permissions are granted to the Oura app, since a missing permission is a common cause of a ring that won't connect.

Using it

How do I update it?
When enabled, your Oura Ring firmware will update automatically as soon as a new version becomes available, without requiring any action on your part.
Do I need a subscription?
A subscription is optional. Oura Membership costs $5.99 a month, and the first month is free. The ring still works without it, but the app then shows only your three daily scores. Membership adds sleep stages, HRV, body temperature and long-term trends.
What does it cost?
It costs $399 to $499. That is the list price, before any subscription.
Does it read blood glucose?
No, it has no glucose sensor. The maker has not published this, so treat it as a best guess.
Does it track sleep apnea?
It watches for breathing disturbances while you sleep. It is a signal to act on, not a diagnosis.
Does it have GPS?
No, it has no GPS. The maker has not published this, so treat it as a best guess.
Does it work with my phone?
Yes, it works with an iPhone or an Android phone.

What is it made of?
It is made of titanium.
What ring sizes does it come in?
It comes in US sizes 6 to 13. Order a sizing kit first, because it is not the same fit as a jewellery ring.
How big is it on the finger?
It is 6.09mm wide and 2.28mm thick. It is thin enough to wear next to another ring.
Does it work with GLP-1 medication?
Yes, it works with GLP-1 medication. There is a dedicated mode for tracking how the medication is affecting you.
Does it take an ECG?
No, it does not take an ECG. The maker has not published this, so treat it as a best guess.

Yes, it tracks your HRV.

Ring sizes 6 to 13. 6.09mm wide, 2.28mm thick (world's smallest)

You can wear your Oura Ring on any finger, but for the best accuracy, we recommend your index finger.

Battery and charging

How do I look after the battery?
Oura's lithium polymer batteries actually perform the best when they're at 25-80%.
How long does the battery last?
It runs 6 days to 9 days. That is 144 to 216 hours.

Water

How do I clean it?
We recommend cleaning the infrared LED sensors (the three small bumps) located on the interior of your Oura Ring approximately once a week. This can be done by wiping them down with the inside of your t-shirt or a piece of cloth, or by rinsing your ring with a small amount of mild dish soap and water.
Can it get wet (shower, pool, swimming)?
Yes, you can shower and swim in it. It is rated to 100m, and for snorkelling.
