Best Sleep Trackers 2024 – Top 8 Tested & Reviewed
I used to wake up exhausted, wondering why eight hours in bed felt like four. To find out what was actually happening after I closed my eyes, I spent the last month testing eight different sleep trackers. From smart rings and wristbands to sensor mats that slide under your mattress, I wanted to see which devices provide actionable data rather than just a confusing graph of light and deep sleep. Testing these wasn’t just about reading spec sheets; it meant wearing multiple devices to bed, comparing their data against how rested I actually felt the next morning, and seeing which apps gave the most useful advice.
The Fitbit Sense 2 quickly became my top recommendation for its deep dive into stress and recovery metrics. If you hate wearing a watch to bed, the Oura Ring Gen3 Horizon is incredibly comfortable, while the Withings Sleep mat removes wearables from the equation entirely. For those on a strict budget, the Amazfit Band 7 and Xiaomi Mi Smart Band 10 offer surprising accuracy for under $50. Athletes who need to know exactly how hard they can push their bodies will get the most out of the Surundo Whoop Band 4.0, and the Garmin Venu Sq 2 is a great middle-ground for runners. Finally, the Muse 2 Headband offers a highly unique, brain-sensing approach for those focused on active meditation before bed.
Top Picks
Welcome to our “Top Picks” for sleep trackers, where we’ve handpicked and tested the best devices to help you catch those Z’s and wake up refreshed. Discover why these standout options made the cut for their accuracy, comfort, and user-friendly features.
Fitbit Sense 2
The Fitbit Sense 2 is a health-focused smartwatch that prioritizes stress and recovery metrics over standard smartwatch notifications. It utilizes an EDA (electrodermal activity) sensor to monitor physical signs of stress, combining that data with your sleep scores to give you a holistic view of your daily readiness. The bright AMOLED display makes checking your morning sleep score incredibly easy before you even get out of bed.
With a 336 mAh battery, the Sense 2 reliably lasted me about five to six days between charges, which is a massive advantage over daily-charge devices like the Apple Watch. At 45.9 grams, it’s light enough that I didn’t find it bothersome overnight. The 1.58-inch screen is crisp, and the updated physical button on the side is a huge improvement over the original Sense’s finicky capacitive groove.
During my testing, the Sense 2’s sleep staging was incredibly accurate. I wore it during a particularly stressful product launch week at work, and the EDA sensor actually caught my physical stress spikes during the day, which directly correlated with a drop in my deep sleep that night. The Fitbit app’s sleep profile feature accurately pegged my sleep style as a “Tortoise” (slow to fall asleep but solid once there). My only real gripe was the built-in GPS; it consistently took about 30 to 45 seconds to lock onto a signal when I started my morning runs.
Verdict
Best Overall. If you want deep stress and sleep analysis on your wrist, the Sense 2 delivers. It lacks the deep third-party app ecosystem of an Apple Watch, but for pure health and sleep tracking, it’s one of the most comprehensive tools available.
Oura Ring Gen3 Horizon
The Oura Ring Gen3 Horizon packs advanced health monitoring into a discreet piece of jewelry. It completely eliminates the distraction of a glowing screen in bed, relying instead on tiny infrared LED sensors, a temperature sensor, and an accelerometer to track your heart rate, HRV, and sleep stages from your finger—where pulse readings are often stronger than on the wrist.
Depending on the size you need, the ring weighs just 4 to 6 grams. I found the battery reliably lasted about six days, and it charges quickly on its proprietary puck. Because it lacks a screen, you rely entirely on the Oura smartphone app to view your daily Readiness, Sleep, and Activity scores. It’s a much more passive tracking experience compared to a traditional fitness tracker.
I usually hate wearing watches to bed, so swapping to the Oura Ring was a massive relief. I barely noticed the titanium band while sleeping. The temperature sensor was particularly impressive; it detected a 1.2-degree spike in my body temperature two days before I actually felt the symptoms of a cold, tanking my Readiness score and warning me to rest. It did, however, log me as taking a “nap” when I was just reading a book on the couch for an hour, and it occasionally counted aggressive typing as steps.
Verdict
Best Premium. Ideal if you hate sleeping with a watch on. It’s a significant investment—especially factoring in the monthly subscription fee—but the comfort, unobtrusive design, and accuracy of the recovery data are unmatched.
Withings Sleep
The Withings Sleep is a set-it-and-forget-it mat that slides under your mattress, offering a completely non-wearable solution. It uses pneumatic sensors to measure your heart rate, breathing rate, and movements through the mattress, syncing the data via Wi-Fi to the Withings Health Mate app as soon as you get out of bed.
The mat measures 25 inches long and requires continuous power from a wall outlet, meaning you never have to worry about charging it. It also features an integrated sound sensor to detect snoring. Because it connects via Wi-Fi rather than Bluetooth, you don’t need your phone nearby for it to log your sleep data.
I was highly skeptical that a mat could read my heart rate through a 10-inch memory foam mattress, but during my two-week test, it matched my wrist tracker’s heart rate data within 2-3 BPM every single night. It was incredibly freeing to just get into bed without strapping anything to my body. The snoring detection was eye-opening (and a bit humbling). The main drawback is the setup: getting the mat calibrated the first time took three tries, and if you share a bed, you’ll need two mats if both partners want their sleep tracked.
Verdict
Best Non-Wearable. The ultimate low-maintenance tracker. If you have an accessible power outlet near your bed and absolutely refuse to wear a device to sleep, this is the easiest and most reliable way to track your rest.
Amazfit Band 7
The Amazfit Band 7 proves you don’t need to spend hundreds of dollars to get reliable sleep data. It’s a budget-friendly fitness tracker that covers all the basics—heart rate, SpO2, and sleep stages—while boasting a battery life that puts premium smartwatches to shame.
The 1.47-inch AMOLED display is surprisingly vibrant for the price point. Weighing just 28 grams, it’s very comfortable for overnight wear. The standout feature is the 232mAh battery; Amazfit claims up to 18 days of battery life, which drastically reduces the chances of the device dying in the middle of the night and ruining your sleep data.
For under $50, I didn’t expect much, but the battery life is real. I charged it exactly once during my entire three-week test period, even with continuous heart rate monitoring turned on. I wore it alongside a Fitbit Inspire 2, and the total sleep duration matched up almost perfectly. However, the Amazfit did struggle with context; it logged me as “sleeping” while I was just sitting still watching a movie on the couch. The heart rate sensor also lagged by a few seconds during high-intensity interval workouts, though it was perfectly fine for resting overnight heart rates.
Verdict
Best Budget. A fantastic entry-level tracker. The battery life alone makes it worth the price, and while the sleep staging isn’t flawless, it provides a great baseline for anyone looking to understand their sleep habits without breaking the bank.
Surundo Whoop Band 4.0
The Surundo Whoop Band 4.0 is built specifically for athletes who want to optimize their training and recovery. It doesn’t count steps or show you text messages; instead, it constantly monitors your heart rate variability (HRV), resting heart rate, and respiratory rate to calculate exactly how much strain your body can handle each day.
The Whoop 4.0 is a screenless fabric band that weighs 27 grams. It features a unique battery pack that slides over the sensor, allowing you to charge the device while wearing it, so you never have to take it off and miss a night of data. All your metrics are viewed in the Whoop app, which requires an ongoing monthly subscription to access.
During a heavy training block for a half-marathon, Whoop’s recovery metrics became my daily guide. After a grueling 10-mile run in the heat, my sleep was restless. The next morning, the app showed my recovery at just 34% (in the “red” zone), prompting me to skip a planned heavy lifting session. I listened, and it likely saved me from overtraining. The sleep coach feature is also brilliant, telling you exactly what time to go to bed to achieve your desired peak performance. The lack of a screen takes getting used to, but it completely removes the urge to check your wrist in the middle of the night.
Verdict
Best for Athletes. The subscription model is pricey, but if you need highly actionable data on how hard to push your body today based on how you slept last night, Whoop is in a league of its own.
Garmin Venu Sq 2
The Garmin Venu Sq 2 balances everyday smartwatch features with the deep health metrics Garmin is known for. It features a square 1.41-inch AMOLED display and includes Garmin’s “Body Battery” metric, which combines your sleep quality, stress levels, and daily activity to show your energy reserves on a scale of 1 to 100.
Weighing 38 grams, it’s comfortable enough for 24/7 wear. The battery life is a major selling point, lasting up to 11 days in smartwatch mode. It includes a pulse ox sensor for tracking blood oxygen levels during sleep, which is crucial for identifying potential breathing disturbances.
I wore the Venu Sq 2 on my left wrist alongside the Fitbit Sense 2 on my right. The Garmin’s SpO2 tracking during sleep felt highly consistent, and waking up to see my Body Battery recharge to 95% after a good night’s rest was incredibly motivating. The built-in GPS was fast and accurate for my outdoor runs. However, digging through the on-watch menus to find my detailed morning sleep score felt a bit clunky compared to the more intuitive Fitbit interface, and the screen was slightly harder to read in direct afternoon sunlight.
Verdict
Best for Smartwatch Features. A great middle-ground for active users who want reliable GPS for their workouts and detailed sleep tracking without having to charge their watch every single night.
Muse 2 Headband
The Muse 2 Headband takes a completely different approach to sleep and relaxation, using EEG sensors to monitor your actual brain activity. Rather than just tracking your movement in bed, it acts as a personal meditation assistant, playing real-time audio feedback (like the sound of a rainstorm) that calms down as your mind settles.
The device weighs 43 grams and rests across your forehead, hooking behind your ears. Because it’s actively reading brainwaves, heart rate, and breathing, the battery life is limited to about 5 hours. It connects via Bluetooth to your phone, where the companion app guides you through various sleep and meditation programs.
Sleeping with a plastic headband takes some getting used to, and I found it best for falling asleep rather than wearing all night. The real-time audio feedback was genuinely effective; hearing the “weather” get stormy when my mind started racing about work deadlines helped me consciously refocus my breathing until the audio shifted back to calm birdsong. However, if you are an active sleeper, the device will likely slip off your head. It fell off twice during my testing, making it better suited for pre-sleep meditation or power naps than full overnight tracking.
Verdict
Best for Meditation and Sleep. Best suited for active meditation and short naps rather than full overnight tracking. If racing thoughts are the main reason you can’t fall asleep, the biofeedback from the Muse 2 is incredibly helpful.
Xiaomi Mi Smart Band 10
The Xiaomi Mi Smart Band 10 delivers a vibrant screen and solid tracking for a fraction of the cost of premium models. It features a pill-shaped design that snaps into a silicone band, offering continuous heart rate monitoring, SpO2 tracking, and detailed sleep stage analysis.
The 1.56-inch AMOLED display is bright and easy to navigate. Powered by a 250 mAh battery, it easily lasted me two full weeks on a single charge. At just 24 grams, it’s one of the lightest wrist wearables available, and the 5ATM water resistance means you can wear it in the shower or pool without a second thought.
During my overnight tests, the Mi Smart Band 10 was so light I forgot I was wearing it. The baseline heart rate data was surprisingly accurate when compared to a chest strap monitor. However, it did consistently overestimate my REM sleep compared to the Oura ring, logging vivid dream states when I was actually just tossing and turning. I also took it into the shower, and the water droplets caused the touchscreen to swipe wildly on its own, so you’ll want to utilize the screen lock feature when wet.
Verdict
Best Value. A highly capable tracker for the price. It provides a great entry point into sleep tracking, offering long battery life and a bright screen, provided you don’t mind slightly exaggerated REM data.
Buying Guide
Form Factor Matters (Wrist vs. Finger vs. Mattress)
The best sleep tracker is the one you will actually use every night. If you find wearing a watch to bed restrictive or uncomfortable, wrist-based trackers like the Garmin or Fitbit will end up sitting on your nightstand. Smart rings, like the Oura Ring, offer a much less intrusive experience and often capture stronger pulse signals from the blood vessels in your finger. If you want zero wearables, under-mattress sensors like the Withings Sleep are excellent, though they cannot track your data if you sleep in a hotel or on the couch.
Understanding the Metrics (HRV, SpO2, and Sleep Stages)
Don’t just look for a device that tells you how long you slept. Look for trackers that measure Heart Rate Variability (HRV) and SpO2 (blood oxygen). HRV is a key indicator of your nervous system’s recovery; a higher HRV generally means your body is well-rested and ready for strain. SpO2 sensors are vital for detecting breathing disturbances overnight, which can be an early warning sign for conditions like sleep apnea. Check out our guide on understanding health metrics for a deeper dive into these terms.
Battery Life and Sleep Tracking
Battery life is arguably the most important spec for a sleep tracker. Devices that require daily charging (like many premium smartwatches) often end up on the charger right when you go to bed. Look for devices with at least a 4-to-5 day battery life, ensuring you can wear them overnight and charge them briefly while you shower or work at your desk.
Watch Out for Subscription Fees
The upfront cost of a sleep tracker isn’t always the final price. Devices like the Whoop 4.0 and the Oura Ring require ongoing monthly subscription fees (ranging from $6 to $30/month) to access your detailed sleep data and personalized insights. Fitbit also locks some of its long-term trend data behind its Fitbit Premium paywall. Always factor in the annual cost of the app when comparing budget vs. premium models.
Conclusion
Finding the right sleep tracker comes down to balancing comfort, data accuracy, and your budget. The Fitbit Sense 2 remains our top recommendation for its excellent blend of stress tracking and sleep staging. If you want a screen-free experience, the Oura Ring Gen3 Horizon is incredibly comfortable, while the Withings Sleep mat is the ultimate low-maintenance option. Whichever you choose, the real value comes from using the data to make small, consistent changes to your bedtime routine.
Frequently Asked Questions
Do sleep trackers emit harmful radiation?
No. Consumer sleep trackers use Bluetooth Low Energy (BLE) to sync data, which emits non-ionizing radiation at levels vastly lower than your smartphone. The optical sensors used to track heart rate (the green or red flashing lights) are just standard LEDs and are completely safe for skin contact.
Can a sleep tracker diagnose sleep apnea?
No consumer sleep tracker can officially diagnose sleep apnea or any other medical condition. However, devices equipped with SpO2 (blood oxygen) sensors can detect significant drops in your oxygen levels overnight. If your tracker consistently shows high breathing disturbances, it is a good data point to share with a doctor or sleep specialist.
How accurate are wrist-based sleep trackers compared to sleep labs?
While they have improved significantly, wrist-based trackers are generally about 70% to 80% accurate at identifying specific sleep stages (Light, Deep, REM) compared to clinical polysomnography (PSG) used in sleep labs. They are, however, highly accurate at determining total sleep time and resting heart rate.
Do I have to pay a monthly fee to use a sleep tracker?
It depends on the brand. Garmin, Amazfit, and Withings offer full access to your sleep data without any recurring fees. Brands like Whoop and Oura require a monthly subscription to view your daily readiness and sleep metrics, while Fitbit offers basic data for free but charges for advanced insights.
Why does my tracker think I’m asleep when I’m just watching TV?
Most wrist-based trackers rely heavily on accelerometers (movement sensors) and a lowered heart rate to guess when you fall asleep. If you are sitting perfectly still on the couch with a low resting heart rate, the algorithm may misinterpret this lack of movement as the first stage of light sleep.
