Best sleep trackers and monitors iMore 2021

If you find yourself waking up every day still feeling very tired and unrested, you could be having sleep troubles you may not know about, and the best sleep trackers could help you get some answers. If you're looking for some at-home analysis about your sleeping habits, try investing in a sleep tracker or monitor. Many of the best fitness trackers have sleep tracking capabilities, making them the best sleep trackers for most people; however, they aren't your only option. Here are the best sleep trackers you can buy.

Fitbit Charge 4

Fitness and sleep tracker: Fitbit Charge 4 (black)

Staff Favorite

The Fitbit Charge 4 can automatically detect when you fall asleep, meaning you don't have to worry about switching modes before you turn out the lights. As you sleep, the Charge 4 monitors your heartbeat and sleep patterns throughout the night, displaying the data in the graphical form on the Fitbit app for your phone. While the Fitbit doesn't track the exact stage of sleep you are in, it does let you know how long you were restless and gives you a total of your time spent in peaceful sleep.

Tons of sleep data: Withings Sleep

Although Withings Sleep is only a pad you put under the mattress, it can give you a ton of data about your sleep. This handy pad measures a plethora of data, which can help determine why you feel so unrested. The pad can measure your heartbeat, bed temperature, air conditions, how many times you roll over, what stage of sleep you're in, and more. All this data is collected and then synced to your phone with a free app, giving you a chance to review it every morning.

Simmons BeautyRest tracker

Personalized sleep coaching: Beautyrest Sleeptracker Monitor

The Beautyrest is a high-tech sleep tracker that features two pads and a processor. The pads go under your mattress on each side to get a better picture of your motion while you sleep. The processor compiles all the data and transmits your sleep details each night to the app. The sensors are so sensitive and accurate that they can monitor respiration and heart rate. Plus, the sleep cycle alarm determines the best time to wake you up so that you feel refreshed. The processor learns your sleep patterns over time so that it can help to provide you with the best sleep coaching possible via the app.

SleepScore Max

Bedside table tacker: SleepScore Max sleep tracking device

If you don't like the idea of having a pad on your mattress, the SleepScore Max will help you get all the data you need from resting on your beside the table. While it can't measure your heart rate, it can still track how deep or light you sleep, based on your movement and breathing throughout the night. Plus, SleepScore will give you a score each night on how well you sleep and coach you through ways to improve that score over time.

Apple Watch Series 6 Blue Aluminum

Best smartwatch with sleep tracking: Apple Watch Series 6 — aluminum case

Adding a blood oxygen sensor and always-on altimeter doesn't seem like a big upgrade, but when paired with everything else the Apple Watch does, this is the most significant upgrade since the Series 4. Plus, with watchOS 7, you can track your sleep every night, set multiple sleep schedules, and even get ready for bed with Wind Down.

Polar M430 in White

Great for runners: Polar M430 (black)

While you may think of the Polar M430 as a great running wearable (because it is), its Polar Sleep Plus system is pretty handy to track your shut-eye. It uses the watch's accelerometer to deliver feedback, and it's quite accurate since it gives you actual sleep time, so your results won't be skewed just by lying in bed. Plus, it will track any interruptions and provide data on continuous sleep periods.

Basic data vs advanced data

Sleep is vital for everybody, but tracking your sleep data at home can be simple or advanced, depending on what you require. Basic sleep data like general sleep quality, time spent in deep sleep, and your sleeping heart rate can be tracked from a wearable. If you're looking for more in-depth, more meaningful data, you'll likely need a device that is on or near your bed. Either way, the best sleep trackers will help you figure out how you sleep and can even help you change your sleep habits so that you can get more meaningful rest.

I find that if you don't need super-advanced insight into your sleep and are just looking for a baseline of how much you toss and turn, the Fitbit Charge 4 fits the bill nicely. It's comfortable to wear, and its battery life is long enough that wearing it to bed won't mean you have to charge it first thing in the morning.

If you crave more in-depth data into your sleeping habits and are looking to improve your sleep, the Beautyrest Sleeptracker is about as advanced as it gets and can even provide personalized sleep coaching to help you get the best rest.

Lastly, we absolutely love Apple Watch Series 6 in our Apple Watch Series 6 review; we mentioned just how happy we are that watchOS 7 added sleep tracking to our favorite smartwatch. It's the best smartwatch with sleep tracking you can buy right now.
