Are you concerned that you may not get quality sleep? Short of going to an actual sleep clinic for medical testing, you can monitor your sleep right at home with a variety of sleep trackers.
Sleep trackers use data gathered from your resting heart rate, heart rate variability and breathing to determine how long you rest and how much time is spent in each sleep stage. Combined, this data can provide valuable insights into the quality of rest you’re actually getting.
There are many types of sleep trackers, and whether you opt for a small wearable like the Oura Ring 4 or an armband-style tracker like the Garmin Index Sleep Monitor, you can see your sleep habits and find ways to improve them to get better rest.

Given the many types of sleep trackers, we aimed to include a diverse array of devices to accommodate people with different preferences. For example, we considered ring, wristband-style, smartwatch, sleep pad and armband wearables for our top picks. We ensured that every pick delivers high-quality, reliable sleep tracking to help customers understand their sleep habits.
There are four primary types of sleep trackers, each with its own pros and cons. It’s a matter of preference, as all can be fairly accurate under the right conditions. Here’s a quick look at all four:
Ring
Smart rings, such as the Oura Ring 4, are the least cumbersome type of wearable sleep tracker. You can sleep comfortably while wearing it without worrying about it slipping off, but there’s no screen to view data, so it’s all accessible only through your smartphone.
Watch
Smartwatches offer solid sleep-tracking accuracy given the right circumstances, and many high-end models, such as the Apple Watch Series 11 and Fitbit Charge 6, provide detailed breakdowns of key metrics, including time spent in sleep stages. However, they can feel a bit clunky to wear while you sleep, and accidental shifting may yield less-than-accurate results.
Under-mattress
Under-mattress trackers, such as the Withings Sleep Tracker, are the least restrictive as they don’t even make contact with your body. They’re excellent for analyzing long-term trends and are easy to set up, requiring only that you place them under your mattress and sync them with your phone. However, they’re generally slightly less accurate than wearables and can be affected significantly by factors such as mattress type and thickness.
Armband
Armband sleep trackers such as the Garmin Index Sleep Monitor are a great alternative for those who don’t like smartwatches or rings, and they usually offer much better battery life. You can typically get up to a week’s worth of sleep data on a single charge, and because your arms move less than your wrist while you sleep, results can be more accurate. However, comfort varies by model, and they typically have fewer sensors than smartwatches, which can lead to less-accurate readings under certain conditions.
Sleep tracking
Although sleep trackers aren’t as precise as medical-grade equipment, they’re usually accurate within 20 to 40 minutes for total sleep time. Accuracy for sleep stages dips considerably because sleep trackers primarily use heart-rate variability and resting heart rate to infer which sleep stage you’re in. Medical-grade devices, on the other hand, use brain waves to track time spent in sleep stages in real time, making them the most accurate method.
Most sleep trackers provide data on various metrics that can help you gain insights into your sleep quality. They vary by device, but generally you’ll get data regarding total sleep time, sleep stages, resting heart rate, heart-rate variability, breathing rate, restlessness, blood oxygen and skin temperature. However, as previously mentioned, heart rate variability and resting heart rate are the two primary indicators for recovery and overall stress.
Overall health tracking
Smartwatches and rings function as complete health and fitness trackers in most cases, meaning you can get readings on various metrics. It depends on the model, but many offer calorie-tracking, breathing rate, blood oxygen, skin temperature and heart-rate monitoring at rest and during workouts.
Sleep stage analyses and calorie burn are the least reliable with wearables, while heart rate, heart-rate variability and step counting are highly accurate. Breath rate and total sleep time can vary depending on sensor accuracy, but the key is to use all readings over time to identify meaningful trends and make adjustments to improve sleep and fitness.
Sleep trackers provide data on total sleep time, heart-rate variability, and time spent in sleep stages. That data can be used to generate trend reports that indicate your overall sleep quality, providing insights into how to improve it. Some sleep trackers offer advice and tips to help you fall asleep faster and optimize sleep recovery.
Battery life varies widely across wearables such as smartwatches, armbands and rings, but many offer up to a week of nightly tracking on a single charge. For example, the Fitbit Charge 6 can last up to six days on a full charge, while the Apple Watch Series 11 typically lasts only a day or two with minimal use. Under-mattress sleep trackers, such as the Withings Sleep Tracker, plug directly into a power outlet, so you don’t need to worry about charging them.
Smart rings look just like your everyday jewelry ring, but they’re very basic and comfortable if you get the correct size for your finger. Smartwatches, on the other hand, vary in size and design. Wristband-style trackers, such as the Fitbit Charge 6, are lightweight and comfortable enough for all-day wear. The Apple Watch Series 11 is also relatively sleek compared to other, bulkier smartwatches. Armbands are thin, and you won’t really feel them as you sleep, although they may feel slightly awkward at first and may take some getting used to.
Under-mattress trackers look like large rectangular pads, but they don’t make any contact with your body. As long as they’re compatible with your mattress, you won’t need to worry about them compromising your comfort.
Many sleep trackers provide basic data reports, but some offer a more comprehensive analysis via paid subscriptions. This is typically true of many smartwatch trackers, such as the Fitbit Charge 6, which also offers features like guided meditations, readiness scores, sleep coaching, and more. Other devices, such as the Withing Sleep Tracker, don’t require any additional subscriptions and provide enough data to gain insights into sleep patterns.
Subscription costs for additional tracking services vary, but they generally range from $5 to $15 per month. They’re optional, but helpful if you want a deeper analysis of your sleep habits.
Sleep trackers collect sensitive health data, and most devices store it in the cloud to sync with your phone. That means your information is present on company servers, not just on the device itself.
In most cases, the risk isn’t anything to worry about. However, it’s worth noting that companies may use data for research or product improvement, and any cloud storage carries some risk of data breaches. If you’re concerned about privacy, it’s best to review the brand’s privacy policy before buying or using a sleep tracker.
A. Smartwatches and rings with reliable sleep-tracking capabilities typically cost anywhere from $150 to $350. Dedicated armband and under-mattress sleep trackers are in the ballpark of $100 to $250.
A. Apart from concerns about cloud privacy breaches, sleep trackers are safe and do not pose any physical health risks. However, there are some reports of users experiencing increased anxiety or stress over sleep habits once they start tracking, which in turn can lead to poorer sleep and overall quality of life.
