Why compare them at all?
They do much the same job. Each is a screen-free tracker you wear day and night, and each reads your sleep, HRV and heart rate, plus blood oxygen and temperature, then sends it to an app on your phone. Both work with iPhone and Android, both are HSA/FSA eligible, and both come with a one-year warranty. With no display on either one, you check your numbers when you feel like it.
You keep a tracker like this for years, and its trends build over weeks and months of wear. That makes it a long purchase, so add the running cost to the price on the box from the first day you compare them. A small monthly fee adds up, and it keeps running for as long as you want the full app. Reason 4 has the three-year totals for both, down to the cent.

Reason 1: Hume's Free App Shows Your Biological Age and Pace of Aging
You'll see Biological Age in the Hume app with no plan at all, and Pace of Aging too. Both are wellness estimates built from what the band tracks. On the Oura side, Cardiovascular Age and Cardio Capacity need an active membership.

Buy the Hume Band once and the app gives you these scores with no monthly charge. Metabolic Momentum, Metabolic Capacity, Pace of Aging, Biological Age and Health Score all come with it. If you want AI coaching on top, that part is optional Hume Premium, starting at $8.99 a month.

- Biological Age plus Pace of Aging: two wellness estimates drawn from your band data
- Metabolic Capacity: your strain, recovery and readiness, scored each day
- Metabolic Momentum: a running score showing if your daily habits are helping or hurting

- Readiness, Sleep and Activity scores stay in the app with no membership
- Cardiovascular Age comes with Oura Membership, $5.99 a month or $69.99 a year
- Cardio Capacity gives you a VO2 max estimate with membership, and new members get month one included
If I bought a tracker for the long view, I'd want my aging scores in the app from day one with nothing to renew, and Hume puts them there. I'd take them as wellness estimates and follow the trend over months. If a VO2 max number mattered more to me, I'd look hard at Oura's Cardio Capacity and budget for the membership.
Reason 2: Skip the Membership and Oura Shows You Three Scores
We went through each company's own product and support pages and listed what its app shows with no paid plan running.


- No subscription is needed for the band itself or for your raw data
- Blood oxygen, skin temperature, HRV and heart rate stay in the free app
- Your health data belongs to you, and you can export it if you ever want a copy

- With no active membership you see Readiness, Activity and Sleep scores
- Ring battery, basic profile, app settings and Explore content stay open too
- Blood Oxygen Sensing, 24/7 heart rate, Daytime Stress and advanced temperature monitoring need a plan
Oura plays fair here. New members get the first month included, and if you cancel without deleting your account, your data stays saved and you can export it as a CSV through the Membership Hub. Years from now, I'd want 24/7 heart rate and blood oxygen in my app with no bill attached, and the free Hume app covers both.
Reason 3: The Band Runs Up to 14 Days a Charge, the Ring 6-9
We read both spec sheets. Oura calls this its longest-lasting ring yet, at up to 6-9 days. The Hume Band runs up to 14.


- With typical use, the band runs up to 14 days before it needs the charger
- 20 to 80 minutes on the charger, depending on battery level
- Frequent syncing and continuous tracking can trim that a little, so read 14 days as the top number

- Up to 6-9 days a charge, depending on ring size and usage
- A charge takes about 80 minutes, matching the band's upper end
- A Charging Case, sold separately, gives a full day of battery in 10 minutes
6-9 days is a lot for a ring that small. The Hume Band's up to 14 days would be my pick, because over a year it adds up to a lot fewer trips to the charger.
Reason 4: $249 vs. $608.97 or $708.97 After Three Years
We added up both price lists over 36 months, before tax, with the membership billed on its yearly plan.

- $249 once, which stays your three-year total on the free Hume app
- Hume Premium is optional and starts at $8.99 a month for AI coaching
- Premium at $8.99 for all 36 months brings Hume to $572.64

- $608.97 on Silver or Black: $399 plus three years at $69.99
- $708.97 on Gold, Deep Rose, Stealth or Brushed Silver: the $499 ring plus the same three payments
- With no membership it stays at $399 or $499, and the app shows three daily scores
I'd price the setup I'd keep using for years. On the free app, the Hume Band comes in $359.97 or $459.97 under a ring with three years of membership. If three daily scores were enough for me, the ring price would be the whole bill.
Reason 5: On Size, Water and Extras, Oura Comes Out Ahead
Oura calls this the world's smallest smart ring, and it leads here. We compared size, water rating and what each paid plan adds.

- A knit wrist band. Extra straps swap in seconds, $49 each
- IP68, rated to 1 meter for as long as 2 hours, fine for swimming
- Optional AI coaching through Hume Premium costs from $8.99 a month

- Titanium, 2.28 mm thick, 6.09 mm wide, weighing from 2 grams
- Waterproof to 100 meters (328 feet), with an IP68 rating
- Membership adds Oura Advisor, Cycle Insights and Daytime Stress
The ring is smaller and goes further underwater, so I give Oura the edge here. Its monthly membership costs less than Hume Premium and includes Pregnancy Insights and Cardio Capacity (VO2 max). The band's best reply is a strap I could change in seconds.
Reason 6: Fit, Returns, and Which One You Should Buy
We went through both return policies and how each one fits. A strap adjusts on the spot. A ring comes in sizes, and Oura offers a free kit to find yours. HSA/FSA is a tie, since both qualify.

- The knit strap adjusts across a wide range of wrists, with no sizing step before you buy
- 45-day returns, conditions apply: like-new, original packaging, bought from Hume
- You pay return shipping unless defective. 1-year warranty, optional 10-year at checkout

- Free Sizing Kit offered, sizes 6 to 13, and Ring 5 fits differently from Ring 4
- 30-day returns, and orders from Nov. 1 to Dec. 31, 2026 have until Jan. 31, 2027
- Prepaid label, one return or exchange per item, 1-year limited warranty
Oura's holiday return window and prepaid label are good. If smallest size or deep water came first for me, I'd buy the ring and keep the membership. If I wanted long-term trends with no ongoing fee, I'd buy the Hume Band.

Hume Band 2.0 takes it, 6 checks to 4
We read both spec sheets line by line, and we'd send most shoppers to the Hume Band 2.0. Oura Ring 5 earns its four checks, and they're good ones. With the membership, you get blood oxygen and temperature readings, Cycle Insights, Pregnancy Insights and a VO2 max estimate through Cardio Capacity. It's also titanium, waterproof to 100 meters, and what Oura calls the world's smallest smart ring. That's a lot of tracker for one finger.
Hume pulls ahead on cost and on what you keep with no paid plan. The band is $249 once. Oura comes to $608.97 or $708.97 over three years on the yearly plan, depending on the finish. Hume's free app holds the core metrics, plus Metabolic Capacity, Metabolic Momentum and wellness estimates of Biological Age and Pace of Aging. One charge can last up to 14 days, against up to 6-9 on the ring, and the adjustable strap means you skip the sizing step before you buy.
Pick by what you'd wear all day and what you'd pay each month. If you want something smaller on your body, water protection to 100 meters, or cycle and pregnancy insights, and $5.99 a month seems fair for that, buy the Oura Ring 5. If you want long-term health trends with no ongoing fee, the Hume Band 2.0 is our pick.

A screenless knit band you buy once for $249. The free app holds your core metrics and aging scores, and one charge can last up to 14 days. AI coaching is optional with Hume Premium, from $8.99/month. You get 45-day returns, and return conditions apply.

"I used to wear an Oura Ring, but after a while I wasn't finding it very helpful. My husband bought a Hume Band and loved it, so I gave it a try too. I've been hooked ever since."
"I used Whoop for a long time but tried the Hume Band because it didn't require a subscription. I was surprised by how much useful data and guidance I found about living healthier."
"I appreciate the updates that keep improving the product. The insights are incredibly helpful, and the strap feels much more comfortable to me."
