Best Sleep Tracker

Countless people do not listen to their internal clock and do not go to bed in time. The next morning, they hardly get up and feel tired and tired all day. With a sleep tracker, which records the sleeping habits exactly, this can be remedied quickly.

Therefore, the 70-head editorial team of the well-known and our neutral consumer portal has collected and analyzed many examinations, studies and customer opinions online in order to list the best sleep trackers in a clear comparison table. Benefit from the findings and find the right sleep tracker for restful sleep.

What is the best sleep tracker and how does it work?

Sleep tracker is a device that allows you to monitor sleep. The device recognizes and records how many times you have awakened during the night, how many hours you slept, when you went to bed, how often you got up or how often you have turned. In short: A sleep tracker documents the complete sleep behavior. The devices are even capable of between the different sleep phases, such as the sleep phase, the light sleep phase, the deep sleep phase and the REM phase to differentiate. Some sleep trackers have a built-in alarm clock, which uses the data on different sleep phases to wake us up at a convenient moment, rather than taking us out of deep sleep.

In addition to the documentation of information about our sleep behavior, many sleep trackers also have the appropriate programs that analyze the data, rate and sometimes even make recommendations. The sleep trackers get to the data for our sleep behavior, for example by using motion sensors. The pulse rate and blood pressure are recorded by many sleep trackers. Professional devices even measure the brain waves. External factors such as the brightness or the sounds around us are also captured by some sleep trackers. In some cases, the sleep trackers have internal software that can evaluate the data, but sometimes they have to go to a smartphone or a computer.

Applications – Sleep tracker in use

Sleep trackers are usually used at night, but can also be used the whole day if they are portable. The sleep trackers can be used for sleep disorders, but can also be used by people who are convinced that they have a good night’s sleep. Apart from the sleep monitoring function, many sleep trackers also have a function that can provide other relevant information about our sleep patterns, such as caffeine or alcohol consumption. Some trackers can also record and assess the activity behavior in addition to the sleep behavior. For example, they count stepsor calculate our general fitness level. This is a combination of sleep and activity trackers.

What types of sleep trackers are there?

1. Sleep tracker as a bracelet

best Sleep tracker as a bracelet

Sleep tracker as a bracelet is similar to a clock, with the portable sleep tracker modeled after the fitness watches. Worn on the wrist, the pulse can be continuously monitored and also other bodily functions and activities are recorded with them. Often, this type – the best sleep tracker and he has an integrated activity tracker, so steps or the like are checked as well. Some of the bracelet trackers work only in combination with the smartphone, which should always be within reach.

2. Sleep tracker for the mattress

If it is too uncomfortable at night to carry something on your arm, you can switch to a sleep tracker for the mattress. This type of sleep tracker can be attached either under the bed sheet or between slatted frame and mattress. The test comparison shows that the trackers have a sensitive motion sensor, with which, for example, nocturnal rolling around and getting up are registered.

3. Sleep tracker for the smartphone

Sleep trackers for smartphones work by recording all sounds from the environment as well as the sleeping person. The smartphone is simply placed next to the pillow. Based on the sound record noise sources are found, which could disturb a healthy sleep. Even the snoring or self-talk during sleep are registered by the app. A sleep phase alarm is often based on heart rate and respiratory rhythm measurements, or it works by using a motion sensor. Compared to a sleep tracker, a sleep phase alarm clock is only interested in awakening us in as favorable a phase as possible. Our sleep behavior is evaluated by such an alarm clock only for this purpose. In the test, however, it becomes clear that several sleep trackers have a sleep phase alarm clock.

This is how best sleep trackers are tested

In a  test comparison of the best sleep tracker different models are selected by various manufacturers and subjected to a comparison. For this purpose, the first test criteria are determined, which serve as a basis for the comparison. The test criteria consider those aspects that are important when buying the best sleep tracker from the customer’s point of view. A comparison table compares the test criteria for each tested model individually. In this way, potential buyers can also talk about individual quickly and easily gain an overview of test criteria . Similarities and similarities between the tested sleep trackers are immediately noticeable. Of course, even in the test comparison itself an evaluation is made and a test winner determined. Of course, in a test comparison, evaluations of a practice test can also be taken into account, because an exclusive comparison of the manufacturer’s information does not say anything about the actual functionality of a product. For this purpose, for example, an analysis of the customer’s opinions can be carried out. Unlike a test in a lab carried out , the customer reviews and reviews also include aspects that only become apparent after long-term use . One of the first steps in one test comparison is the definition of the test criteria, as these are the starting point for the comparison. In the following, we will briefly introduce and explain the test criteria for sleep trackers.

1. Test criterion heart rate and pulse

This test criterion looks to see if the sleep tracker measures heart rate and/or heart rate. Based on the heart rate can be assessed in which sleep phase someone is currently. Because, in the phase of light sleep, the heart rate slows down automatically. Even if it is a sleep tracker with integrated fitness function, the test criterion is an important factor. In this way you can, for example, at monitor his heart rate, endurance sports. Mostly, the heart rate is measured directly on the wrist.

2. Test criterion Measurement of environmental factors

The test criterion “environmental factors” includes aspects that can prevent us from sleeping peacefully. If you live near a busy street, the sounds of passing cars could have a negative effect on your sleep behavior. Create there are scattered sunrays or lantern light through your curtains, the light could also disturb your quiet sleep. The ambient temperature or the humidity are also detected by some of the best sleep trackers. The test criterion is therefore important if you want to know if the conditions under which you sleep might be optimized.

3. Test criterion respiratory rhythm

Just like the heart rate , the test criterion “breathing rhythm” can also tell you which sleep phase you are currently in. In addition, this feature monitors the regularity of your breath, which can be a problem especially with snorers who suffer from short-term respiratory arrest (sleep apnea).

4. Test criterion motion sensor

The motion sensor can tell how often we get up at night, how often we turn around and how much time we spend quietly in our bed. The test criterion is not only of interest, if you want to know how calm you sleep. Rather, it can also be used as an indicator of which sleep phase we are currently in.

5. Test criterion functions

What do you expect from your best sleep tracker? Should he only monitor your sleep? Or should he also wake you up in a particularly favorable phase? Would you like the tracker to monitor and evaluate your activities?

6. Test criterion battery life

This test criterion compares how long the batteries or the battery last. This aspect is particularly important for those who are accompanied by their sleep tracker day and night because you want to use it as an activity tracker or want to monitor their heart rate 24 hours a day.

7. Test criterion memory and evaluation

Some devices have internal memory and evaluate the data themselves, while others only work with an associated app, others require software to be installed on the computer. Also in terms of storage capacity, there are differences that are considered in this test criterion. The evaluation may also vary in the test comparison of one device to another, and this also depends on the analyzed measurement criteria. Common flaws and vulnerabilities – I must pay attention to this when buying a sleep tracker!

 


Evaluations and tables incomprehensible

Buyers of their best sleep trackers criticize that the evaluations of the different sleep data are incomprehensible. Instead of concrete recommendations or an indication of what is negligible in terms of sleep behavior, tables and diagrams are obtained that are not very meaningful or that require specialist knowledge in order to be able to classify the results. It is also criticized that the evaluations on the smartphone are hardly recognizable given the screen size. So if you want a concrete statement about your sleep behavior, without having to analyze the tables yourself, you should inform yourself in a test comparison before buying  .

Motion sensor inaccurate

In many of the best sleep trackers, the pedometer does not work exactly. For example, you state that you have taken several steps while sleeping, even if you have not gotten out of bed at all. For the user therefore is completely unclear for what reasons come to the error. For example, the device could have misinterpreted movements in bed. Other buyers criticize that the device did not recognize when they woke up or turned. In order to obtain the most accurate results on the sleep behavior, it is, therefore, useful to make sure in the test comparison that the sleep tracker uses different aspects for the assessment, instead of relying solely on the motion sensor.

Device stops measurements

Another weakness in the equipment concerns crashes in the measurements. Some sleep trackers stop the measurement as soon as you get out of bed. Of course, this is inconvenient for those who get up at night to use the bathroom. Other shoppers complain that the device stops monitoring as soon as the Internet connection or connection to the cell phone breaks down. Sometimes there’s no reason why the sleep tracker interrupted the recording. Unfortunately, such deficiencies can often only be detected in the practice test . Again, it is therefore advisable to look at the experiences of previous buyers.

Sleep is not detected automatically

In some reviews, one finds that the sleep tracker hardly fulfills the desired function of sleep monitoring . Devices are advertised as sleep trackers that recognize neither sleep, let alone sleep phases. Instead, you have to manually set the tracker to sleep mode. When you get up in the morning, you have to quit the sleep mode and the device indicates in percent or in hours how long you slept and how long you should have slept. Wake up phases or other evaluations are not considered. In general, such small information and records on sleep behavior are more likely to be on devices that are primarily intended to serve as a fitness bracelet. So if you want to buy a fitness bracelet, in which the sleep analysis is just an extra, should pay close attention to what the tracker measures exactly. In the  test comparison  , you can check this on different criteria. Because only an evaluation of the hours, which one spent daily in the bed, is probably for most persons a little bit information.


Worth knowing & advice

The evolution of the sleep tracker over time

For the development of sleep trackers, two inventions can be considered authoritative. On the one hand, the idea of sleep trackers is based on the so-called sleep laboratories, in which the sleep behavior of people with insomnia is observed in a professional manner. On the other hand,  sleep trackers have become popular  on the market since fitness bracelets have spread successfully. In the late 1960s, the world’s first sleep laboratory was opened at Stanford University , located in Palo Alto, California. The laboratory was set up by the scientist and pioneer in the field of sleep research William C. Dement. Although there have been previous studies on the sleep behavior of humans, these were only carried out for scientific purposes. However, Stanford University’s sleep lab was also focused on diagnosis and treatment. In Germany, the first sleep laboratory was built a little later in the early 1970s. It was housed in the Neurological Clinic of the Hessian Diaconal Center Hephata. The German Society for Sleep Research and Sleep Medicine (DGSM) is still based there. In sleep laboratories, people are medically evaluated during their sleep. Various measurements such as brain activity, movements, heart rate or respiratory rhythm are performed. Sleep trackers make it possible to monitor sleep in a significantly reduced form.
