A great merit in this belongs to the SLEEP STAGES functions. It allows you to see how much time you spent at each stage of sleep: in the surface, deep and phase of the rapid movement of the eyes. By itself, this information carries little meaning, but here the other technology will come to the rescue - Sleep Insights. It will help advice how to improve sleep quality and will explain how each indicator is affected on well-being. In addition, in the application you will get access to statistics, which will compare your indicators with other users from your age group.

And now let's talk about specific devices.

Fitbit Inspire HR is a thin stylish and very clever bracelet. It will be a good choice thanks to a decent line of autonomous service (up to five days) and the functions of round-the-clock monitoring of heart rate. CCC data is stored at intervals of one second, accurate both in physical exertion mode and in calm state.

Wearable products from Xiaomi are in demand due to an affordable price and good characteristics. Mi Band 4 is one of the best sleep trackers in the price range up to 5 thousand rubles.

It is thin and easy enough to not cause discomfort in a dream. Like FitBit Inspire HR, the new MI BAND offers cardiac rhythm monitoring in 24/7 mode and gives a sleep estimate based on how much time you spend in deep, surface and fast phases. He also provides a sleep quality analysis and reminds of the importance of regular recreation. But compared with expensive alternatives, his informativeness is a bit limited.

The MI FIT application itself is also not perfect. The main inconvenience is that the developers have distributed user history for several menu items instead of place it in one tab. However, MI Band can send data to other similar applications, such as Google Fit and Sleep AS Android. Try each and select the one that will seem more convenient.

Before other Mi Band 4 trackers, it has another advantage - it is able to work up to 20 days from one charge. It also knows how to identify the main types of physical activity, check the steps and calculate the amount of calories spent. It does not have its GPS, MI Band 4 geolocation data takes from a smartphone via Bluetooth.

This device monitors respiratory performance with echolocation, that is, a contactless way, absolutely not disturbing you.

Radio waves of low length scan the human body 16 times per second and even the slightest movements. Like other trackers in this list, Sleepscore Max recognizes sleep stages, provides general information about the quality quality with the assessment. But the key feature is a set of sensors for environmental monitoring.

But all these nuances are insignificant, considering how accurate and informative is the device.
