What Oura Ring does well
Oura has earned its reputation, particularly for sleep tracking:
- Excellent sleep staging — The ring form factor sits closer to arteries, providing accurate sleep stage detection.
- Comfortable 24/7 wear — Many find a ring easier to sleep in than a watch.
- Temperature tracking — Skin temperature changes can predict illness and menstrual cycles.
- Discreet design — Looks like jewelry, not tech.
- Long battery life — 5-7 days between charges.
Why Apple Watch users choose My Bio Age instead
Biological age tracking
Oura provides readiness and sleep scores but doesn't calculate biological age. My Bio Age combines 12 health metrics—including VO₂max, which Oura can't measure—into the MyBioAge Index™ that shows your body's functional age and how it's trending over time.
VO₂max integration
VO₂max is the single strongest predictor of longevity. Apple Watch estimates VO₂max during outdoor workouts; Oura Ring cannot measure it at all. My Bio Age incorporates VO₂max as a primary biological age driver—something Oura simply can't offer.
No additional cost
If you already own an Apple Watch, My Bio Age is completely free. Adding Oura means $299-$549 upfront plus $72/year for the subscription. Over three years, that's $515-$765+ for data your Apple Watch already collects.
One device simplicity
Wearing both an Apple Watch and Oura Ring means two devices to charge, two data sources to reconcile, and two ecosystems to manage. My Bio Age consolidates everything into the device you're already wearing.
Complete privacy
Oura syncs all health data to their cloud servers. My Bio Age processes everything locally on your iPhone—your sleep, HRV, recovery scores, and AI conversations never leave your device.
When Oura Ring makes sense
Oura may still be worth considering if you:
- Don't own an Apple Watch and prefer ring form factor
- Find wearing a watch to bed uncomfortable
- Want dedicated temperature tracking for cycle prediction
- Prefer the discreet jewelry-like design
Can you use both?
Some users wear both Apple Watch and Oura Ring. If you go this route, My Bio Age can still provide value by synthesizing Apple Watch data (including VO₂max) into biological age insights that Oura doesn't offer. The apps serve complementary purposes.
However, most Apple Watch users find My Bio Age delivers the recovery and readiness insights they were seeking from Oura—plus biological age tracking—without the extra device and subscription.
