NEW Oura Ring 5: Didn't See That Coming!

Main summary

Key takeaways

Product Review

Product overview (what’s being discussed)

The video discusses the newly announced Oura Ring 5, focusing on what changes vs Oura Ring 4 and whether it improves heart-rate tracking during exercise. This is not yet a full review—the speaker is ordering units and planning a more scientific comparison.

Key new / changed features mentioned

1) Smaller, thinner, lighter ring

  • “Up to 40% thinner” and smaller/lighter (the exact context for the measurement isn’t specified).
  • Expected benefit: improved comfort during sleep, which could improve long-term wear consistency.
  • The speaker expects they’ll adapt quickly to the size, so comfort isn’t their main interest.

2) Health Radar / “blood pressure signals” (not true cuff BP)

  • A new feature called blood pressure signals.
  • The speaker emphasizes an important distinction: these are not direct blood pressure readings like 120/80.
  • Likely approach: Oura may use indirect signals (e.g., optical pulse wave/biometric trends) to detect cardiovascular strain or elevated risk, especially over sleep.
  • Key limitation: the ring signals cannot be compared to cuff-based readings in a straightforward way.
  • Planned testing ideas:
    • Compare against people with high BP, or
    • Correlate Oura signals vs repeated cuff measurements over days/weeks
  • The video suggests accuracy/meaningfulness depends on how Oura presents these results in the app.

3) Nighttime breathing

  • Adds a longer-term view of breathing patterns/disturbances during sleep.
  • Potential value: breathing disturbances can affect sleep quality and recovery.

4) Software / proactive health additions

  • Mentions:
    • GLP-1 insights
    • health record imports
    • more proactive health tools
  • Speaker’s view: these are largely software-layer features and may not mean the underlying sensors are more accurate. They could be added to older hardware but are being introduced with Ring 5.

5) Workout heart-rate tracking: redesigned sensor architecture

Oura’s claims:

  • Redesigned sensor architecture
  • More powerful LEDs
  • Improved skin contact

Online reports also suggest fewer signal pathways, e.g. “12 instead of 18.”

  • The speaker notes this could be counterintuitive, but better LED strength/contact and positioning could still improve signal quality.

6) Live activity / workout experience in the app

  • Adds more “real-time workout experience,” such as pace and distance.
  • But there’s a reported implication: the ring may not stream live heart rate like a chest strap.
  • If that’s accurate, the speaker suggests you might need an external monitor for live HR, potentially due to:
    • battery/streaming constraints, and/or
    • lower confidence in ring-based live HR or reliance on heavier post-processing.

Expected performance based on the speaker’s reasoning

Sleep tracking

  • The speaker expects no dramatic change from Ring 4.
  • Rationale: sleep is a “best case” for ring optical sensors (minimal movement).

  • They expect:

    • sleep HR/HRV
    • and sleep stage tracking to be similar or slightly better, not drastically different.

  • They reference past Oura performance: sleep stage algorithms have been among the better ones (including sleep lab experience mentioned).

Exercise heart-rate tracking

  • Biggest focus: whether Ring 5 improves optical HR during workouts.
  • Speaker is cautiously optimistic for steady-state activities such as:
    • running
    • walking
  • More skeptical for:
    • cycling (handlebar grip can interfere; ring PPG from the finger becomes harder)
    • weight training / rowing (motion/fatigue and PPG stability issues likely)
  • Main concern: ring HR can fail if the ring is:
    • slightly loose,
    • on the wrong finger,
    • rotated,
    • affected by temperature and changes in blood flow
  • Planned approach: test how forgiving the new design is across users and conditions.

Comparisons made

Against a chest strap reference: Polar H10 (ECG chest strap)

The speaker plans comparisons beyond simple averages, including:

  • lag
  • peak detection
  • dropouts
  • performance during intervals

Broader ecosystem context

  • Mentions Apple Watch expanding into hypertension / blood pressure notifications, making Oura’s cardiovascular push feel timely.

Pros / cons mentioned (as stated or implied)

Pros (potential)

  • More comfortable form factor (especially during sleep).
  • New cardiovascular-oriented insights (blood pressure signals, strain over time).
  • Nighttime breathing insights.
  • Potentially improved workout HR due to sensor redesign (LED power + skin contact).

Cons / limitations

  • Blood pressure signals are not true cuff-style systolic/diastolic values; testing and interpretation will differ.
  • Live workout HR might require an external monitor (if ring HR isn’t streamed live).
  • Exercise HR may still struggle in challenging sports vs chest straps/wrist monitors.
  • Software features don’t necessarily mean improved raw sensor accuracy.

Numerical / rating information

  • Numerical claims explicitly mentioned:
    • Up to 40% thinner
    • Sensor pathways reported: 12 instead of 18
  • No star ratings or review scores are given.

Overall verdict / recommendation (based on the video)

The launch is described as solid and logical, but not “spectacular.” There isn’t a single feature that clearly revolutionizes everything. The speaker’s main interest is conditional: wait for real data, especially whether Ring 5 improves heart-rate accuracy during cardio exercise versus an ECG chest strap (Polar H10).

Unique points mentioned (complete list from the subtitles)

  1. Oura Ring 5 is announced and is up to 40% thinner, smaller, lighter.
  2. Smaller ring could be more comfortable during sleep and improve wear consistency.
  3. Speaker expects to adapt to size quickly.
  4. Main question: what changed besides size vs Ring 4.
  5. No sample provided yet; speaker orders two Ring 5s themselves.
  6. New “Health Radar” feature: blood pressure signals.
  7. Blood pressure signals are not direct systolic/diastolic cuff readings.
  8. Ring likely detects cardiovascular strain/elevated BP risk indirectly, likely during sleep.
  9. Ring can’t directly compress artery like a cuff; measurement is indirect (optical pulse wave/biometric trends).
  10. Testing approach: compare against high-BP persons or correlate with repeated cuff readings.
  11. Added nighttime breathing insights.
  12. Software features: GLP-1 insights, health record imports, and proactive health tools.
  13. Speaker separates software features from whether sensors are more accurate.
  14. Ring 5 has redesigned finger optical HR sensor architecture: - more powerful LEDs - improved skin contact
  15. Reports suggest fewer signal pathways: 12 vs 18.
  16. Fewer pathways could still improve accuracy if signal quality is better.
  17. Exercise HR tracking is hard for rings due to motion, grip, blood flow/temperature, and fit.
  18. Running/walking might be easier than cycling, rowing, intervals.
  19. Speaker’s past experience: rings haven’t worked well on them for exercise HR.
  20. Speaker will test on other people to see variability/forgiveness.
  21. Live activity tracking adds pace and distance in-app.
  22. Possible limitation: ring may not provide live workout heart rate like a chest strap; might require external monitor.
  23. Hypotheses for that limitation: battery streaming constraints or uncertainty/processing needs.
  24. Oura historically strong for nighttime metrics (HR, sleep stages) because users are still.
  25. Speaker’s expectation: sleep stage tracking on Ring 5 remains very good/similar, possibly slightly better.
  26. Expect sleep HR/HRV and sleep stages to be similar (not dramatically different) if raw signals are similar.
  27. Overall: solid launch, logical, not revolutionary; includes smaller size, better battery claims, redesigned sensors, proactive health, more cardiovascular insight.
  28. Mention of Apple Watch hypertension/blood pressure notifications as industry timing.
  29. Biggest excitement/goal: whether sensors improve HR tracking during cardio (running/cycling).
  30. Planned detailed comparison vs Polar H10 using lag/peaks/dropouts and interval performance (not just averages).
  31. Expect improvement may be best for steady-state, but may still underperform wrist-based monitors.
  32. Skepticism for cycling (handlebar grip affects finger PPG).
  33. Lower hopes for weight training/rowing.
  34. Speaker will test sleep stage metrics (HRV, nighttime HR, sleep stages) and validate health signals vs physiology.
  35. Viewer prompt to subscribe for scientific review.
  36. Affiliate/discount messaging (not product performance, but mentioned).
  37. Mentions links to a cheaper “Fitbit Air” video and prior Oura Ring 4 review (context for comparisons).
