Apple Watch Series 11 came out ahead in a Wall Street Journal health-and-fitness wearables comparison that measured sleep, heart-rate tracking and workout performance against Oura, Fitbit and Whoop. In the test, WSJ technology columnist Nicole Nguyen paired the $399 Apple Watch Series 11 against the similarly priced Oura Ring 5, the $100 Fitbit Air, and Whoop’s MG sensor, which requires a $199-per-year subscription.
The comparison matters because it puts Apple’s latest watch alongside devices built specifically around health tracking, and it does so with a clinical benchmark in the mix. As part of the analysis, Nguyen completed a sleep study with Stanford Health Care’s Sleep Medicine Center, giving the wearables a reference point beyond day-to-day use.
Apple Watch stood out in sleep tracking
According to Nguyen’s findings, Apple Watch was the strongest performer in the sleep category. The watch recorded the same sleep duration as the lab result, down to the minute: six hours and 52 minutes. Its sleep staging also aligned most closely with the results from the clinical study.
That detail is important because sleep tracking is one of the main reasons many people buy a wearable in the first place. Devices often promise a blend of convenience and insight, but accuracy can vary depending on the hardware and the algorithms behind it. In this comparison, Apple’s watch did best when its data was measured against a sleep lab rather than just compared casually with the other products.
Fitbit’s Air band was the next closest match in Nguyen’s report, with Oura following behind. The result suggests that Apple Watch Series 11 is not just a general-purpose smartwatch with health features attached, at least when it comes to overnight monitoring.
Heart-rate tracking favored Apple’s watch
Apple Watch also held up well in heart-rate monitoring and workout tracking. Nguyen reported that, during a bumpy outdoor bike ride and a relaxed walk with a stroller, only Apple Watch remained relatively accurate.
In another summary of the test, Nguyen wrote that the Apple Watch “excelled across every activity.” That is a strong statement for a mainstream smartwatch competing against devices that market themselves as purpose-built health tools. It also suggests Apple’s sensors and software continued to perform consistently when movement got messy, which is often where wearables can struggle.
The Whoop MG could match Apple Watch, Nguyen said, but only when the sensor was worn on the bicep. That detail is notable because it highlights how placement can affect results. A wrist-worn device, a ring and a strap-based sensor can all behave differently depending on the activity and where the sensor sits on the body.
By contrast, the Fitbit Air and Oura appeared to lose reliability during periods of high activity. Nguyen said both faltered when the pace increased, which suggests Apple Watch may have an edge for users who want a single device to cover both everyday wear and more demanding exercise sessions.
No subscription required for key data
Another advantage Apple Watch brought to the comparison is that it provides accurate results without requiring a paid subscription to unlock the data. That is a meaningful differentiator in a market where some wearables keep core insights behind monthly or annual fees.
Whoop, in particular, is built around a subscription model, with the MG sensor tied to a $199 annual plan. Oura also has paid tiers for some features, so Apple’s approach stands out as simpler for buyers who want to pay once for the hardware and still access the main health data they bought it for.
For many consumers, the subscription question is not just about cost, but also about the long-term ownership experience. A device can look cheaper up front and still become more expensive over time if important features sit behind a recurring payment. In Nguyen’s comparison, Apple Watch’s ability to deliver strong results without that recurring lock-in appears to have been part of its appeal.
How the four wearables compared
Nguyen’s test covered four devices with different form factors and pricing models:
- Apple Watch Series 11 — $399
- Oura Ring 5 — similarly priced to Apple Watch
- Fitbit Air — $100
- Whoop MG sensor — works with a $199/year subscription
The lineup is useful because it spans the most common wearables categories: a smartwatch, a smart ring, a lower-priced fitness band and a subscription-based sensor system. That makes the comparison less about a single head-to-head battle and more about how Apple’s all-purpose watch stacks up against specialists.
The outcome, at least in Nguyen’s reporting, was that Apple Watch Series 11 did best where accuracy mattered most. Sleep duration, sleep staging, heart rate and active workout tracking all seemed to favor Apple’s device, especially when the pace picked up or the movement became less predictable.
Why this comparison matters for Apple
Apple has spent years building health features into the Watch line, and comparisons like this one help show how that strategy performs outside Apple’s own marketing. The Series 11 is not simply competing on style or smartwatch convenience. It is also being measured against products that have earned followings by focusing almost entirely on wellness data.
That the Apple Watch performed favorably in a sleep study-backed comparison suggests the company’s health push remains one of its strongest differentiators. It also reinforces a broader point that has shaped the wearable market: the best device is not always the one dedicated to a single function, but the one that balances day-to-day usefulness with reliable tracking.
For someone choosing between these products, the trade-offs are now clearer. Oura offers a ring format that some users may prefer, Fitbit keeps the price low, and Whoop emphasizes a subscription-driven health platform. Apple Watch Series 11, meanwhile, appears to offer strong all-around performance without needing users to pay extra for the core data.
Current pricing and availability
Apple Watch Series 11 is currently priced from $299 on Amazon, which 9to5Mac notes is a 25% discount from the regular $399 price. That makes the device more accessible than its list price, while still leaving it above lower-cost fitness bands like Fitbit’s Air.
For buyers trying to decide whether to spend more on Apple’s watch or look to a cheaper or more specialized wearable, the WSJ comparison gives Apple a solid case. Its showing in sleep, activity and heart-rate tracking suggests that Apple Watch Series 11 can compete not just as a smartwatch, but as a serious health tracker as well.
