Sleep Tracker Buying Guide
What is a Sleep Tracker – and How Does it Work?
A sleep tracker is an advanced machine that detects your sleep patterns to offer insight into improving your sleep quality.
While lab-based sleep tests detect these patterns by observing your brain activity, sleep trackers rely on sensors that observe physical data like heart rate, breathing, and body movements.
So how does a sleep tracker work?
A wearable sleep tracking device senses physical signs like the heartbeat, breathing rate, and body movements, while a non-wearable tracker uses echolocation to obtain this data unobtrusively.
Nearly all sleep trackers upload this data to a device that runs it through an algorithm to analyze and determine when you are asleep or awake.
Sleep trackers provide accurate and consistent results, so you can obtain a personalized sleep pattern from the comfort of your home without having to spend a night at a laboratory.
Why Buy a Sleep Tracker?
A sleep tracker is a smart and convenient way to obtain accurate sleep analysis. You can use the data to adopt better sleep habits to wake up refreshed and well-rested.
Here are some other reasons why you should buy one:
Improve sleep quality
You can use your sleep tracking device to keep track of your sleep cycle. With this information, you can devise strategies to improve the quality of your sleep. Developing a good night-time routine allows you to sleep deeply so that you wake up feeling fresh and recharged.
Track hours of sleep
The primary task of a sleep tracker is to track your hours of sleep. The hours of sleep that a person needs per night varies, and monitoring your sleep shows you the ideal number of hours you personally need each night.
Troubled sleep really decreases your productivity the following day. Using a sleep tracker helps improve your productivity by ensuring that you get adequate and restful sleep.
Sleep trackers with smart alarms also wake you up gently so you do not feel groggy.
Help address sleep-related issues
While it is not diagnostic, a sleep monitor’s tracking capabilities can detect snoring and demonstrate patterns of restless sleep cycles. You can use the data to conduct important conversations with your doctors to screen for sleep apnea and other sleep-related concerns.
Types of Sleep Trackers
While there are many models and variations of sleep trackers available on the market, they can be widely categorized into two categories; wearable sleep trackers and non-wearable sleep trackers.
Wearable Sleep Trackers
As the name suggests, wearable sleep trackers are devices that you put on your body. They are available as watches, rings, wristbands, and headbands. Many of these often double as fitness trackers to record your physical activities throughout the day.
Non-wearable sleep trackers don’t go over your body. Instead, they either go underneath your bed or stay on the side table to record your sleep cycle.
You can choose between pads, sensing devices, and even sleep monitoring mattresses. They usually connect with your smartphone via apps to display the data.
What to Look for in a Sleep Tracker
Given the different forms of sleep trackers available, it can be hard to settle on one. To make things easier, below are a few features you need to look for when buying a sleep tracker.
As mentioned above, sleep trackers are of 2 types: wearable and non-wearable. Your choice depends on whether you want to wear the sleep tracker on your body or have it record the data unobtrusively.
Many people believe wearable sleep trackers are more accurate, but there’s no concrete evidence or studies that back this up. So, it all comes down to your comfort.
If you are comfortable wearing something on your wrist, finger, or head, then go for a wearable sleep tracker. But if you find such sleep accessories inconvenient, you can invest your money in a non-contact sleep tracker.
Nearly all sleep monitoring devices have small display screens to show metrics.
Meanwhile, non-wearable bed monitors come with compatible smartphone apps where you can view your complete sleep analysis.
When choosing the best wearable sleep monitoring device, ensure that the display screen is large enough to understand the data.
As for contact-free sleep trackers, make sure that the accompanying smartphone app is compatible with your phone and boasts a user-friendly interface with good reviews.
Most sleep trackers sync with their compatible apps to send you daily notifications about your sleep quality and routine. For this purpose, some require you to pay a monthly subscription fee, while others are free to download.
Devices that offer helpful insight to improve your sleep routine and overall sleep quality offer more value, even if they come for a small cost. Most of the free trackers only provide limited, unactionable information, so you can’t really do anything about it.
The build material of a sleep monitor is very important to consider, especially when it comes to a wearable model.
Before making the purchase, make sure that the device is comfortable to wear 24/7. Most feature a minimal design with adjustable wristbands in a variety of colors. But make sure that the material is non-irritating and you are not allergic to anything.
On the other hand, most non-wearables are either a thin strip, fabric pad, or a thin cover that lies on your mattress. Make sure it is comfortable to lie on and does not change your mattress’s feel.
Similarly, sleep trackers that sit on your bed stand should be sturdy and durable enough to withstand accidental falls.
Most wearable sleep trackers are battery-operated. Meanwhile, most non-wearable ones require a power outlet, while a few require USB charging.
If you only want to use your sleep monitoring device for sleep tracking, there’s nothing to worry about, as most are designed to last at least through the night.
However, if you plan to use the device to track your activity throughout the day, then you need to consider the battery life.
Sleep trackers record an array of data to predict your sleep pattern. This includes heart rate, heart rate variability, respiration, snoring, time awake, time sleeping, sleep interruptions, and body temperature.
Some high-end units also detect room temperature, humidity, noise level, and light. Using the data, they also provide tips for the most restful sleep.
When shopping for a suitable sleep tracking device, pay attention to the specific product details to find an option that collects the information you are interested in the most.
Benefits of Using Sleep Trackers
Sleep trackers tell you the state of your sleep and offer you insight on how you can get a more restful one. Here are some more benefits of using one:
- Enables you to practice a better sleeping routine
- It helps you learn about your optimum hours of sleep per night

Frequently Asked Questions
Does a sleep tracker record data if the power goes out briefly overnight?
Unfortunately, electrically-powered sleep trackers cannot work during a power outage. These devices need to stay plugged in to record data ad require a continuous, uninterrupted power supply.
However, if you have a battery-operated sleep tracker, then a power outage won’t affect its functioning. It will continue to record data normally unless, of course, if the battery dies.
Does my phone need to be in the same room as my sleep monitoring device to track my sleep?
No, your phone does not necessarily have to be in the same room as your sleep tracker to monitor your sleep, and you can even put it away in a separate room. As long as both are synced with each other and have network connectivity, the devices will continue to collaborate to track your sleep cycles.
Do I have to wear a specific device to bed for using my sleep tracker?
It really depends upon the type of sleep tracker you have.
A wearable sleep tracker can be a ring, a watch, a wristband, a sock, or a headband that you have to wear to bed.
Meanwhile, a no-contact sleep tracker slips under the bed or sets it on the nightstand to monitor your sleep.
Will the sleep tracker data be affected if a partner shares my bed?
Again, this depends upon the type of sleep tracker you have.
In the case of a wearable sleep tracker, sharing the bed with a partner won’t significantly impact the data it records. But if you have a non-wearable one, your partner’s physical signs may affect the data collection.
Final Verdict: What is the Best Sleep Tracker Sold Today?
Although sleep trackers are not medical diagnostic devices, they can help facilitate underlying medical issues.
After looking at the vast range of sleep tracking devices, we believe that the Fitbit Versa 2 is the best sleep tracker that provides accurate sleep analysis.
Meanwhile, the Withings Sleep – Sleep Tracking Pad is one of the best and most accurate non-wearable sleep trackers.
Lastly, if you want a sleep monitor for your baby, Owlet – Smart Sock 3 Monitor is a good option that is easy to use and provides prompt alerts.
