The 8 Best Sleep Trackers of 2025 According to Our Sleep Experts

Kettlebell enthusiasts will also appreciate that you don’t have to worry about removing or reorienting your band to protect your tracker before workouts. One issue however is that the Ring Air doesn’t track workouts automatically and the process needs to be initiated from within the accompanying app. Still, it’s a minor issue that’s outweighed by just how discrete the Ultrahuman Ring Air manages to be in daily use. Despite its discreet nature, the Ring Air can track your heart rate throughout the day and pick up on any potential anomalies therein. It can even be worn to bed as the Ring Air uses a temperature sensor to record the quality of your sleep, giving you a recovery score similar to what you’ll find on the Whoop Strap 4.0.

While the Garmin Fēnix 8 has the capabilities to track pretty much any metric you want tracked, the charging experience fell a bit short for Thorp. While the battery can last up to 29 days on low power mode, if you switch the GPS on, that number drops down to just under 24 hours of charge—a stark difference. Additionally, Thorp found the charging cord a bit short and keeps these USB-C charger extension cords on hand to charge his https://megagrass.com/community/question-and-answer/forums/4133-general-questions/topics/2805151-mad-muscles-for-fat-loss-anyone-tried-it Garmin.

In a test, we found that the battery had dropped to 9% after 18 hours of use, so if you’re traveling overnight, be sure to bring a charger. The Fitbit Charge series of fitness trackers have always been reliable in tracking steps and distance. In our 1-mile distance test, the Charge 6 was -0.02 miles off and had an error rate of 1.3% in our step-count test, performing just below our pick. After two days of use, our battery was at 68%, putting it slightly off pace with the company’s estimate of lasting seven days. We also evaluate features such as step counting and sleep monitoring, distance calculations, and when applicable, GPS and heart rate accuracy. And, we see how well a manufacturer’s battery life claims hold up in real-world testing.

The best fitness trackers and watches we’ve tested

And since Google bought Fitbit, there are more integrations with Google Maps, Google Wallet, and YouTube Music. Be aware that some features are locked behind a Fitbit Premium subscription, which costs $10 per month. Key specs include an extra-long battery life (Nothing promises 13 days), blood oxygen monitoring, stress tracking, and precise heart-rate monitoring and location tracking. For a smartwatch that often goes on sale for $79, that’s frankly hard to believe. Anthony Chavez, a master trainer at CorePower Yoga, is also a Whoop fan, and like Chatterjee, he appreciates the focus on overall health and behavior.

At NBC Select, we work with experts who have specialized knowledge and authority based on relevant training and/or experience. We also take steps to ensure all expert advice and recommendations are made independently and without undisclosed financial conflicts of interest. While you can use the Oura Ring without a subscription, you’ll be limited to the current day’s sleep, readiness and activity scores. If price is more important to you than features like dual-band GPS, Training Load and Training Readiness, the aforementioned Garmin Vivoactive 6 or make for great, cheaper alternatives. The most important are Training Readiness, Training Status and HRV (heart rate variability) Status, which work in tandem to help optimize your training and recovery.

Xiaomi Mi Smart Band 9

During our Oura ring Generation 3 review, we found that whenever we woke up feeling groggy and poorly rested, this sleek wearable was able to show us exactly when our rest had been disturbed and how it had affected our REM sleep. The Amazfit Active is light, comfortable to wear and packed to the brim with useful features (including GPS navigation, compass and Alexa voice assistant), but it only costs $89. This durable GPS smartwatch has some of the best sports modes and fitness tracking features money can buy, and it looks great, too.

She wore it for working out, commuting, sleeping, and every activity in between. Prior to testing the Ultra, she was already very familiar with Apple Watches—she’d owned the Series 4, 6, and 7. The latest Forerunner 265 impresses with its vibrant AMOLED display and size options, according to Tom’s Guide, while delivering precise GPS tracking and sophisticated training analytics.

The Whoop MG packs medical-grade ECG and daily blood-pressure tracking into a sleek, screenless band. But the hefty subscription and occasional auto-tracking blind spots mean it’s a luxury. The Whoop MG (buy now) packs medical-grade ECG and daily blood-pressure tracking into a sleek, screenless band.

A Smartwatch That Detects Movements Automatically

Are you a hardcore data cruncher, or is it more about staying active in general? The Garmin Connect app is less intuitive than apps from competitors like Fitbit and Apple — give yourself time to get used to it before dismissing it outright. In an effort to try as many options as possible, we contacted and received products from many brands, including (but not limited to) the ones on this list. News and World Report points out that the Plus version acts as a mini command center for your digital life, handling everything from music control and calendar checks to contactless payments and hands-free calls via Bluetooth.

They sound better, deliver a superior noise cancellation experience, enable a bunch of AI-powered conveniences, and even throw a heart rate sensor into the mix. The display on the Forerunner 265 also got a huge upgrade from its predecessor, as it ditched the MIP (memory-in-pixel) display for a modern AMOLED with 416 x 416 resolution. That means everything is easy to read, blacks are black, and colors are super vibrant and pop out at you.

The ScanWatch Light can track over 40 workouts (some automatically), although data is generally limited to heart rate (including zones), steps, distance and pace. The Whoop is less of a fitness tracker and more of a 24/7 personal coach—if your coach were a data-obsessed genius. After wearing it for several months, I realized its greatest asset is its ability to help you optimize your overall performance and recovery. Its strain and recovery scores are the type of feedback that can move the needle in terms of meeting your goals, especially if you’re the type who struggles to know when to push harder or when to rest.

She also liked that she was able to sync the monitor to her treadmill to have more accurate heart rate readings during her treadmill runs. To test each watch’s health tracking, I wore each tracker to sleep, to the gym and during every activity or rest period in between. This gave me a comprehensive view of each tracker’s capabilities and accuracy. When analyzing health tracking, I examined the types of insights each tracker provided about my sleep, cycle and stress levels, and the specificity of each.

At this point, almost every tracker goes past splash and sweat resistance to hit a 5 ATM rating, meaning the device can withstand pressure equivalent up to 50 meters (164 feet). These should be fine to wear in the shower, in the ocean, or in a hot tub. Look for a tracker with built-in GPS that can not only follow you underwater but also accurately track your laps and pace.
