Oura Ring vs Apple Watch: Which Is the Better Health Tracker in 2025?
If you’ve been scrolling TikTok or browsing wellness blogs in the past year, chances are you’ve seen people raving about the Oura Ring and the Apple Watch. Both are considered some of the best fitness trackers on the market, and both claim to give you the most accurate information about your health, sleep, and activity.
But here’s the thing: while they complement each other beautifully, they’re actually designed with different needs in mind. If you’re stuck deciding between them, or wondering whether you should splurge on both, this guide will break down the main things you need to know.
I’ll share my real experience with both devices (the Oura Ring Gen 4 and the latest Apple Watch) and get into the nitty-gritty: from sleep tracking and HRV to step count, strength training, calorie burn accuracy, and even what happens if you lose weight and your Oura Ring stops fitting.
Let’s get into it.
First Things First: How They’re Different
-
The Oura Ring is a discreet smart ring designed for recovery, sleep, and overall wellness insights. It gives you data like your readiness score, heart rate variability, respiratory rate, skin temperature, body temperature trends, and detailed sleep stages. Think of it as the best smart ring for holistic health tracking.
-
The Apple Watch is a smartwatch that focuses heavily on fitness tracking, step count, activity scores, built-in GPS, workout apps, heart rate zones, and calorie burn. It’s part of the larger Apple ecosystem, so you get text messages, phone calls, watch faces, and easy access to third-party apps right on your wrist.
So while both fall into the “health tracker” category, they don’t exactly compete — they serve different features and different goals.
Fit Issues with the Oura Ring No One Tells You About
Here’s something I wish I knew before buying my Oura Ring: if you lose weight, your ring may not fit anymore.
The Oura app suggests wearing the ring on your index finger for the most accurate information. But when I lost 30 pounds, my Oura Ring quickly became too loose on my index finger, and it slipped around on my other fingers too. And unfortunately, Oura only offers a 30-day exchange program. After that, you’re stuck buying a brand-new ring — which is not cheap.
It’s also worth noting that ring sizers don’t work as a fix, since they block the sensors that track your health metrics. So if weight loss is part of your journey, consider that extra cost before committing.
Fitness Tracking: Apple Watch Takes the Lead
If your goal is weight loss, fitness, and calorie burn accuracy, the Apple Watch is the clear winner.
-
Step count: The Apple Watch consistently tracks more steps than the Oura Ring. The ring sometimes lags or doesn’t even recognize treadmill walks, while the Apple Watch picks them up instantly.
-
Calories burned: Apple’s fitness data is more reliable, especially when paired with heart rate monitoring during workouts.
-
Strength training: The Oura Ring can be uncomfortable because it pinches your finger against the weights and scratches very easily. (Weightlifting gloves help, but it’s still annoying.) Also, there have been any times I found the Oura ring did not pick up the strength training as activity despite how heavy I lift. The Apple Watch, on the other hand, tracks reps, sets, and calories with a workout app.
-
Built-in GPS: Perfect for runs and outdoor workouts. The Oura Ring doesn’t have this.
If you’re serious about activity tracking, workout apps, and accurate calorie burn, the Apple Watch is hands down the better choice.
Sleep Tracking: Oura Ring Does a Great Job
When it comes to sleep tracking, the Oura Ring shines.
-
It breaks down your sleep stages (light, deep sleep, REM sleep).
-
You’ll see your sleep score, which combines how much sleep, your restfulness, and recovery metrics.
-
It tracks heart rate variability (HRV), resting heart rate, respiratory rate, and even body temperature trends (helpful for spotting illness early).
-
Women love the Oura’s menstrual cycle and Natural Cycles/Flo integrations — it can actually help predict periods and ovulation using body temperature shifts and I’ve found it to be very accurate.
While the Apple Watch has made strides in sleep tracking, the Oura Ring feels more in-depth, consistent, and less distracting to wear overnight. Its long battery life (up to 5 days on a single charge realistically) also means you don’t have to worry about plugging it in every night, unlike the watch. It is also fully charged in less than an hour.
If sleep is your main focus, the Oura is the best smart ring and easily one of the best available sources of sleep data.
Comfort & Design: Ring vs Watch
-
Oura Ring: Extremely comfortable for all-day wear and while sleeping. You barely feel it’s there. The downside? It’s easy to scratch and not ideal during strength training or anything involving heavy weights. Some people also don’t like wearing it on the same hand as their wedding ring.
-
Apple Watch: Bulkier to sleep in, but versatile. You can change your watch face and bands to match your style. It’s water resistant, and the latest Apple Watch Series feels sleeker than older models. Plus, the added benefit of being able to check calls, texts, control your music, etc.
Terms of design, it really comes down to whether you prefer the discreet smart rings style or a more obvious smart device on your wrist.
Health Metrics & Wellness Features
Both devices give you health data and wellness features, but in different ways:
-
Oura Ring: Focused on recovery metrics like HRV, readiness score, sleep quality, and skin temperature. Great for monitoring stress levels, overall health, and recovery.
-
Apple Watch: Focused on real-time fitness tracking, heart rate zones, calorie burn, and activity scores. It also tracks blood oxygen levels, heart health, and even potential sleep apnea risks.
Both integrate into the Apple health app for easy access, and they can share fitness data if you use both devices.
Subscription Fees & Apps
-
Oura Ring requires a monthly subscription fee to unlock all its health metrics, readiness score, and wellness features. It’s $6/month.
-
Apple Watch doesn’t require a subscription for its core health tracking, though you can connect it with third-party apps or apple devices for extra features.
It’s a small but important difference if you’re comparing long-term costs.
Battery Life: Oura Ring vs Apple Watch
-
Oura Ring: Claims up to 7 days of use on a single charge. I find I get about 5 days.
-
Apple Watch: Around 18–36 hours, depending on the model. The Apple Watch Ultra has longer battery life, but you’ll still charge it much more often than the Oura.
So if you hate charging devices constantly, the Oura wins here.
Do They Work Together?
Yes — and honestly, they do a great job complementing each other. This ended up being the way I went.
The Oura Ring tracks recovery, sleep data, and readiness. The Apple Watch tracks workouts, step count, and calorie burn. If you connect them, the Oura app can integrate with what your Apple Watch tracks and they are extremely accurate together.
If you’re a wellness nerd like me, having both is amazing because you get real-time data from workouts + deeper recovery metrics from sleep.
Final Verdict: Oura Ring vs Apple Watch
So… which one should you buy?
-
For weight loss, fitness, and step count accuracy → Go with the Apple Watch. It’s the better choice if your goal is fat loss, calorie burn tracking, and staying active. It also doubles as a smart device for phone calls, text messages, and more. And you wont have to worry about it not fitting/replacing it in a few months if you lose weight.
-
For sleep tracking, recovery, cycle tracking, and stress levels → The Oura Ring is unmatched. It’s the best smart ring for sleep data, recovery metrics, and discreet health tracking.
-
For overall health → Honestly? If you can afford it, get both. They’re different devices that serve different purposes, and together they’re one of the best fitness trackers setups you can own.
At the end of the day, it comes down to your personal goals. If you want a clear winner for fitness and weight loss, the Apple Watch edges ahead. If you want to optimize recovery, sleep quality, and wellness, the Oura Ring is the better choice.
