Evaluating the feedback from users and also reflecting on the version of the new device, the creators managed to achieve outstanding results.

In fact, the menu is controlled by a swipe up and down and also has the function of a touch tapping on the screen. If the user needs to return to the previous menu, this can be done with the help of a button on the screen. The main innovation is also the fact that the novelty has a color AMOLED-display, which primarily makes the gadget more informative, presentable, and enjoyable to use.

It is also worth noting that if in the previous version of the notification gadget from various applications it was not very easy to read, then in the new version of the tracker each notification from different applications has its own icon and helps the user to identify their purpose quickly.

This, in turn, makes it much faster to understand which of the functions are activated in the settings (they are marked in green) and also to see the functions of the cancel buttons which are indicated in red, respectively.

In the updated version of the fitness tracker, management has become somewhat more comfortable as the swipes to the left and to the right are no longer used.

However, as in previous versions, this device has an incredibly high autonomy battery life.



Fitness Tracking Workout Modes

Despite the fact that modern treadmills always contain such useful functions as the calculation of speed, calories burned, and pulse, these data are often not accurate. That is why Xiaomi Mi Band comes to the rescue here. Based on this, it is worthwhile to more thoroughly understand why the fitness tracking function of this gadget is incredibly convenient and accurate for everyone who plays sports.

Treadmill & GYM Exercises
