Tracker weighs only 21 grams, so it almost does not feel on the hand, even during sleep. We provide examples of SMA B2 people with different dimensions: adult men strap is no pressure, the bracelet does not fall with the most slender girls. All comfortable.
To SMA B2 should be almost no stranger: in a couple of hours, I had forgotten that I go to the tracker at hand. Therefore, such a watch is difficult to forget at home, because they do not need to be removed to arm "rested".
it is necessary to pull out the strap, then insert into any USB-port for charging an "internal" bracelet. This means that no wires to carry with you do not need: it is enough to remove the tracker to get the "stuffing" and insert it into the nearest laptop.
Main functions
Let's start with the fact that we can see directly on the tracker screen. Indicators are accompanied by symbols, and animations: do not need to understand, everything is clear from the first turn.
A few words on the screen: bright lights, the characters are unreadable when a very strong light. Apparently, the tracker is integrated gyroscope: the screen of the wrist turn on him, he illuminates itself, no need to press the button. Conveniently!
At SMA B2 displayed seven screens:
- Main. It shows the time, date and day of the week, as well as Bluetooth status and battery life.
- Screen pedometer. Shows steps passed, and when you long press a single button - the distance in kilometers and the approximate number of calories burned.
- Screen pulse. Your heart rate, expressed in bpm.

Also, the bracelet can vibrate for incoming calls and messages are received, and it means that the phone can be removed from the pocket in the backpack without fear of anything to miss. More functions - in the application.

To measure pressure, you need to remove the bracelet from the arm and attach the sensor to the pad of your finger. Then proceed to a pressure screen and hold down one button. After 10-15 seconds, pressure indicators appear on the screen and in the tracker application.
Developers emphasize that measuring blood pressure - the technically complicated process requiring special equipment, and that the error results SMA B2 can be 10-20%. In addition, you must comply with all the conditions, as well as the measurement of classical tonometer: sit back, relax, do not cross your legs and do not talk.
SMA B2 is not a medical device. Based fitness tracker performance and without medical supervision should not take the drug.
But to make a decision about going to the doctor, guided by SMA B2 indicators possible. Remember, if your age is 20-40 years, the pressure should be 120-130 70-80.
Using the application
The application displays the statistics of activity and exercise, heart rate, pressure, and sleep quality. You can view the data for any day that you are wearing a tracker. If you exercise, the SMA B2 will provide ample opportunities for analysts: for example, after a treadmill workout you can see at what speed and frequency of steps you ran, how many calories burned and how to change your heart rate during running. Given the fact that athletes should always monitor the heart rate during exercise, it is a very useful feature.
Here you can also set the alarm clock and set the data refresh rate pulse. From it depends on how quickly discharged your tracker.

I'm testing a bracelet in a week, and discharged while he obviously does not intend to.
