Oura Ring Gen 4

Rating: 4.2/5 ⭐⭐⭐⭐☆

I've been wearing the Oura Ring Gen 4 for 3 months after upgrading from Gen 3. At $349, this is Oura's most expensive ring yet. Here's whether the improvements justify the premium price.

First Impressions & Upgrades

The Gen 4 looks nearly identical to Gen 3 from the outside. Same titanium build, same color options, same general size. The real changes are internal - new sensors and improved algorithms.

Oura claims better accuracy, longer battery life, and new health features. After 3 months, some promises delivered, others didn't.

Build Quality & Design

What's The Same:

• Premium titanium construction

• Water resistance for swimming

• Comfortable all-day wear

• Scratch-resistant finish

• Same sizing system as Gen 3

What's Improved:

• Slightly better weight distribution

• More consistent sensor contact

• Refined charging dock design

• Better durability around sensor areas

If you own Gen 3, the physical differences are minimal. Build quality remains excellent but isn't a huge upgrade reason.

New Sensor Technology

This is where Gen 4 tries to justify its price increase.

Improved Heart Rate Monitoring: More accurate during workouts and daily activities. I compared it to my Apple Watch - Gen 4 tracks much closer than Gen 3 did.

Better Sleep Detection: Sleep/wake times are more precise. Catches short naps I take that Gen 3 missed completely.

Enhanced HRV Tracking: Heart rate variability readings seem more consistent and reliable for recovery insights.

New SpO2 Monitoring: Blood oxygen tracking is new for Oura. Works decently but not as accurate as dedicated pulse oximeters.

The sensor improvements are real, but incremental rather than revolutionary.

Battery Life Reality

Oura promised longer battery life. Here's what I actually get:

Gen 4 Performance: 5-7 days typical use, sometimes pushing 8 days with minimal features enabled.

vs Gen 3: Maybe 1-2 days longer on average. Not the dramatic improvement I expected.

Charging: Still takes 2-3 hours for full charge. New dock is slightly more stable but still easy to lose.

Battery improvement exists but isn't game-changing.

Sleep Tracking Accuracy

What's Better:

• More accurate sleep stage detection

• Better temperature tracking consistency

• Improved sleep onset detection

• Fewer "restless sleep" false positives

What's Similar:

• Still occasionally misses naps

• Travel/timezone changes still confuse it

• Alcohol detection remains hit-or-miss

Sleep tracking is noticeably better but not dramatically different from late Gen 3 firmware updates.

Fitness & Activity Tracking

Improvements:

• Heart rate during workouts is much more accurate

• Better step counting consistency

• Improved workout detection

• More reliable activity goals

Still Limited:

• No built-in GPS

• Manual workout starting required

• Can't replace a proper fitness watch

• Limited exercise types recognized

Gen 4 is better for fitness tracking but still not a Garmin or Apple Watch replacement.

The Subscription Model (Still $6/Month)

The controversial subscription remains unchanged.

What Requires Subscription:

• Detailed sleep insights

• Advanced recovery recommendations

• Workout heart rate zones

• Trend analysis beyond 7 days

• Most useful features

My Take: At $349 + $72/year, you're paying $421 the first year for a fitness tracker. That's Apple Watch Ultra territory with way more features.

The subscription model feels even more expensive now that the hardware costs more.

App Experience & New Features

App Improvements:

• Faster sync times

• Better data visualization

• More detailed insights

• Improved recommendations

New Health Features:

• Blood oxygen trends

• Enhanced stress monitoring

• Better meal timing insights

• Improved cycle tracking

The app experience is genuinely better, making the data more actionable.

3-Month Real World Use

Daily Comfort: Just as comfortable as Gen 3. Forget I'm wearing it most days.

Accuracy Improvements: Heart rate tracking during workouts is noticeably better. Sleep data feels more reliable.

Battery Consistency: Slightly better than Gen 3 but not dramatically. Still charging twice a week.

Durability: Holding up well to daily gym sessions and swimming.

Value Analysis at $349

This is the big question - is Gen 4 worth $349?

What You're Paying For:

• Better sensor accuracy

• Improved algorithms

• New health metrics

• Enhanced app experience

• Premium build quality

What You're Not Getting:

• Revolutionary new features

• Dramatically better battery life

• Freedom from subscription costs

• Fitness watch capabilities

Gen 3 vs Gen 4 Comparison

Should Gen 3 Users Upgrade? Honestly, probably not unless accuracy is crucial for you. The improvements are nice but not essential.

For New Users: If you're buying your first Oura ring, Gen 4 is worth the extra $150 over Gen 3 for better accuracy and future-proofing.

Competition Reality

vs Apple Watch SE ($249): Apple Watch has more features, better fitness tracking, but worse sleep monitoring and battery life.

vs Garmin Vivosmart 5 ($150): Garmin offers similar health insights without subscription but lacks Oura's sleep accuracy.

vs Fitbit Sense 2 ($200): Better value for most people unless you specifically want the ring form factor.

Who Should Buy Gen 4

Perfect For:

• First-time smart ring buyers

• Sleep optimization enthusiasts

• People who hate wearing watches

• Those wanting the latest health tracking

• Users who can easily afford the subscription

Skip This If:

• You own Gen 3 and it works fine

• $349 + subscription feels too expensive

• You need comprehensive fitness tracking

• You want GPS or smart notifications

• Budget is a primary concern

3-Month Verdict

The Oura Ring Gen 4 is incrementally better than Gen 3 in meaningful ways. Sleep tracking is more accurate, heart rate monitoring improved, and the app experience is enhanced.

But at $349, it's entering premium territory where competition offers more features for similar money.

For Existing Gen 3 Users: Skip the upgrade unless accuracy issues bother you daily.

For New Users: It's a solid choice if you want the ring form factor and can afford ongoing subscription costs.

Real Talk

Oura improved the right things with Gen 4 - accuracy and reliability. But they also increased the price significantly without adding revolutionary features.

The ring form factor remains unique and comfortable. Sleep tracking is genuinely excellent. But $349 + $72/year puts you in premium device territory.

I'm keeping mine because the improved accuracy matters for my health tracking goals. But I understand why many people will stick with Gen 3 or choose alternatives.

Final Thoughts

The Oura Ring Gen 4 is a solid evolution rather than revolution. Improvements are real but incremental. At $349, you're paying premium prices for premium health tracking in a unique form factor.

If sleep optimization is your priority and budget isn't a concern, Gen 4 delivers. But there are more cost-effective ways to get health insights if you're not committed to the ring format.

The subscription model remains the biggest value hurdle. Great hardware hampered by ongoing costs that feel expensive relative to alternatives.

Bottom Line: Better accuracy and features than Gen 3, but $349 + subscription makes it a premium purchase for a specific audience. Excellent if you can afford it, expensive if you can't.
