Our team has studied the market of modern fitness gadgets and now can talk about the most worthy activity trackers & wristbands models for every taste and budget on Amazon through 2018! An active lifestyle and regular exercising have become the latest fashion trend. People are increasingly beginning to change a comfortable chair to the gym. This allows you to make the body beautiful and health strong. There is no way without progressive gadgets that should always be with you. Fitness trackers collect critical information about the state of the body and then demonstrate the results to the user.
Modern technologies not only simplify our lives, but some of them are also created to take care of the health and fitness of their users. For example, fitness trackers that track physical activity, measure the pulse and monitor the phases of sleep. Therefore, they can immediately identify problems. On April 7, World Health Day, we decided to remind you how important it is to take care of your health and prepared a rating of 7 good fitness trackers that will not hit the wallet a lot.
The devices allow you to track your physical activity, such as walking, jogging, cycling and more. In particular, it is possible to find out how many steps you have walked, how long you have played football or skied.

What can be measured

• time;
• number of steps;
• calories;
• distance (not for an exercise bike);
• weight (to start it must be entered manually).
  Fill out a profile to get information about how many kilometers you have traveled and how many calories you have burned.

Before proceeding to the consideration of specific models, it is necessary to determine the selection criteria by which you can compare devices with each other and filter out inappropriate options.

1. Price
   There are many devices on the market with a variety of prices, and there are excellent options in the price range up to 100 US dollars. It is important to determine the necessary functions that you really will use and not overpay for excessive functionality.
2. Platform
   A full-fledged OS is built only in a smartwatch. Trackers are often synchronized with smartphones and display all the information in a mobile application. Therefore, compatibility is an important point to pay attention to before buying.
3. Functionality
   The basic functionality is almost identical in all devices: the number of steps, the distance traveled, calories burned. For many, this is more than enough. In more expensive models, there are additional indicators: heart rate, diet, and weight tracking, GPS support and the ability to answer calls.
4. Autonomy
   Battery life is very important for mobile devices. Smartwatches due to their more powerful filling and display are much smaller than conventional fitness bracelets. The latter work from one charge for about a month, whereas with the clock everything is not so optimistic. A smart gadget will have to be charged, if not every day, then at least once every 2-3 days.
