Ageon vs Oura: know how you're aging without a ring
Oura is a smart ring that's best known for sleep. Its membership adds readiness, Cardiovascular Age and more. Ageon is an iPhone app that scores six domains from three quick tests and Apple Health, estimates your age from the inputs that change most with age, then helps you test which habits move it.
| Ageon | Oura | |
|---|---|---|
| What you need | An iPhone. Apple Watch, rings and smart scales are optional. | An Oura ring, from $349. |
| Cost | Free to start. Premium is $5.99 a month or $34.99 a year, with a 7-day trial. | $5.99 a month or $69.99 a year membership, on top of the ring. |
| Age estimate | An Ageon Score across six domains, and an Ageon Age estimated from the inputs that change most with age, like VO2 max, push-ups and balance. | Cardiovascular Age, from heart data over about two weeks. It covers the heart only. |
| How it's calculated | Published, with every reference table, weight and source. | Described in Oura's help pages. Formula not published. |
| Strength and mobility | Sit-to-rise, push-ups and a 10-second balance test. The iPhone camera can count push-ups and time the balance test. | Not measured. |
| Daily tracking | Daily summaries from Apple Health. No device of its own. | Sleep stages, readiness, temperature, heart rate and HRV from the ring. |
| Testing what works | Try one change for 7 to 56 days and compare your readings with the four weeks before. It shows what changed, not proof of cause. | Tags you add to days, shown against your readings. |
Where Oura is the better pick
Sleep tracking is the main thing you want. A ring worn every night measures sleep closely, and Oura's sleep features are mature.
You want temperature trends or cycle insights. Ageon doesn't do either.
You're on Android. Ageon is iPhone only.
Where Ageon is different
The whole picture, not just the heart. Cardio is 30% of the Ageon Score. The rest is strength, sleep, activity, body composition, and mobility and balance.
No ring and no membership to start. The tests take a few minutes with a chair and a floor.
The method is public, down to each reference table and study.
Experiments compare your own readings before and during a change, so you can see what moved for you. They show a difference, not proof that the habit caused it.
Which should you choose?
Pick Oura if sleep is your focus and you'll wear a ring every night. Pick Ageon if you want an estimate of how you're aging across your whole body, and help finding what changes it, without new hardware. Oura can also write sleep and heart data to Apple Health, which Ageon reads.
Questions
Is there an Oura alternative without a subscription?
Ageon has a free tier that includes the Ageon Age estimate, Pace of Aging and Blood age. It needs no ring. Premium is optional.
What is Oura Cardiovascular Age?
An estimate of your heart's age from the ring's heart data, shown after about two weeks of wear. It looks at the heart only, not strength, balance or body composition.
Can I use Ageon with an Oura ring?
Yes. Turn on Apple Health sharing in the Oura app. Ageon reads what Oura writes there, such as sleep and heart rate.
Ageon gives wellness estimates, not diagnoses. No app or wearable measures biological aging directly. Prices are in US dollars and can change, so check each product's own page before you buy.
