In theory, health trackers should do the same thing: monitor your activity and provide easy-to-understand insights. However, in practice, these devices function very differently.
Take the Oura Ring and the Apple Watch, for example. You can exercise with both of them, wear them to bed, and keep them in the shower as they monitor your heart rate, body temperature, activity, stress, and sleep.

But they couldn’t be more different. The smart ring promises a discreet build and a few days of battery life (Aura says seven days max, but from my testing it’s closer to four or five). A smartwatch, on the other hand, is a bulky device that brings all the features of your smartphone to your wrist with a health and activity-minded twist.
So which one should you buy? I wear both devices regularly, because I enjoy the functions of each device for different reasons. Let’s sort out the differences.
You should buy Apple Watch if…
1. You want a smartphone assistant
The Apple Watch is like a mini version of your iPhone that tracks your health data. It can do many of the same things your phone does, but it acts as a bridge to your phone for functions like answering calls, replying to messages, and controlling music.
It still feels like an accessory for your smartphone, but Apple has definitely improved the health-tracking capabilities of the watch. For example, its recently announced FDA-approved hypertension detection feature is a first for the device.

Personally, I use mine apple watch series 11 To check the hourly forecast, respond to messages, set a timer when I’m cooking or working out, activate Siri when I have a question or order, and navigate directions. The Apple Watch notifies me when I’m in a noisy environment, and when I’ve been motionless for too long, it tells me to stand up.
For all these reasons, the Apple Watch is for people who want the same information they can get on their iPhone (albeit with a few more health-minded notifications and functions throughout the day) — but wrapped around their wrist instead. You may work in a busy environment where checking your phone throughout the day is looked down upon. An Apple Watch can keep you connected and in the loop even when you’re on the floor.
2. You care more about activity tracking than sleep tracking
As a recreational runner and gym goer, I’ve found the Apple Watch to really shine with activity tracking. It records my runs in the workout app with speed, heart rate, and active calories burned. It also notifies me of per-mile splits and tells me when I’ve closed my rings for the day.

But it’s not just running and walking; You can record a lot of workouts using the Apple Watch. In fact, the Apple Watch is great for swimmers and water-based activities, with the Apple Watch seeing significant improvements in water. First of all, the watch has a swim-proof design with 50-meter water resistance, so it’s a device that isn’t afraid of getting wet.
Its lap counting feature and custom workout feature let you set up your own circuits, while a depth gauge and a water temperature sensor provide specific insights. If you’re a surfer or regularly swim in the ocean, Apple has introduced a Tides app that provides tidal information, such as forecast for high and low tide, direction, and sunrise and sunset information.
Weight trainers will also get the most benefit from the Apple Watch as it doesn’t recommend lifting weights while wearing rings. Additionally, I’ve found the Apple Watch’s Training Load feature helpful in assessing my exertion rate during weight lifting sessions.

Activity tracking is at the heart of the Apple Watch: It pings you to take off your fitness ring, stand up, and keep moving after inactivity. While the Ora Ring also has activity tracking features, if you want exercise data at a glance or you’re in the water, the Apple Watch will be better for you.
3. You want a personalized wearable item
Unlike smart rings, which come in a maximum of three to five colors, the Apple Watch comes with a wristband that you can easily change, depending on what fabric, color and style you want to wear that day. Pair it with a sleek chain or down for a sweaty workout session. For these reasons, it is more customizable as a wearable technology.
Plus, Apple Watches come with all kinds of complications for customizing your watch face display. Some displays give smartwatches an analog feel, while others offer buttons to activate exercise, display parts of the screen and activity rings to check the weather forecast or heart rate history.
You should buy Ora Ring if…
1. You only care about health data tracking
The Oura Ring works really well as a health tracker, but it doesn’t offer all the bells and whistles of the Apple Watch. But as far as sleep tracking goes, I’d take my Aura ring over an Apple Watch any day of the week for all the comprehensive data it can provide.
Through Ora Ring, I’ve learned my sleep chronology, understood what causes physical stress throughout the day, understood when and why my heart rate drops at night, and benefited from the helpful summaries it provides each morning. As I’m writing this, Ora’s symptom radar feature is telling me that my body is showing major signs of stress — and it’s right. I have congestion and cough. It was discovered the morning I had my first symptoms.

While the Apple Watch provides numbers like how long you slept and the different stages of sleep, the Oura Ring provides the context behind those numbers with unmatched health data visualizations that anyone can understand. One of my favorite aspects of Ora Ring is the app’s ability to illustrate your health data in a way that doesn’t overwhelm but informs.
It also regularly introduces new features that have transformed the smart ring, as Aura’s CEO described it, into “a doctor in your pocket”, such as the aforementioned symptom radar feature.
2. You want more advanced sleep tracking
Wearing a watch in bed is not for everyone. There have been many nights when the bulky device on my wrist kept me awake. The Oura Ring, on the other hand, is lighter and more discreet as a sleep tracker. Plus, at seven days, its battery life is longer than the Apple Watch’s one or two days, so you don’t have to charge it as often or worry about it running out of power while collecting sleep data.
In my opinion, the sleep score is one of the most important data visualization features a sleep tracker can offer. Getting a rating on a 100-point scale is universally understandable and provides a benchmark against which you can improve. Ora offers many useful ways to improve your sleep, and the Sleep Score function is a good way to start.
The Apple Watch recently launched a sleep scoring feature, although you won’t get as detailed a breakdown of sleep as the Oura Ring provides. It evaluates sleep on a few things, (sleep consistency, duration, and interruptions) and it is much easier to get a higher sleep score on the Apple Watch than on the Oura Ring.

Just keep in mind that the sleep score is not an empirical indicator of sleep health. However, it does provide a useful overview with recommendations for maintaining or changing sleep habits for the best possible sleep.
3. You want to keep it a secret
The Apple Watch offers various customization options with a selection of different watch faces and bands. In contrast, smart rings are the opposite: their construction is discreet and lack any customization in physical form.

When I wear smart rings, most people are surprised to find out that they have any technological capabilities at all. Most smart rings come in gold, silver, or black varieties and are, for the most part, indistinguishable from regular rings (until they start glowing green or red to track my activity or sleep). This form factor makes them lighter, more comfortable, and with far fewer distractions.
author’s choice
The short answer is: it depends on what I’m looking for. I have tested both ora ring and this apple watchAnd find them useful for various things. For unobtrusive sleep tracking, I have to hand it to the Ora Ring. For activity tracking and training data, it’s pure Apple Watch.
For a discreet wearable that I don’t have to fiddle with or test, the Ora Ring takes the cake. For a convenient, mini iPhone that helps me check my messages, set timers, and query Siri when my phone isn’t around, the Apple Watch is the winner.
