The latter two come with heart rate sensor, barometric altimeter which gives you more insight on your intensity helping you know when to scale up or down your intensity, and is also great choices for tracking climbing activities. However, the Vivofit 4 being a basic activity tracker lacks some fitness tracking features present on the Vivosport and Vivosmart 4. Each of these three can track your steps, distance, sleep, calories burned and as well can remind you after a long period of inactivity.

The major difference between these three is in the available sensors and subsequently fitness tracking features. The Vivosmart 4 also has the most stylish design with the aluminum bezel lining the top that leaves it with a more decent appearance, while also weighing a bit less than the other two which no doubt makes it the most befitting wear. Although, the display of the later two are easier to read outdoors compared to the Vivosmart 4. However, the Vivosmart 4 powered by OLED has a more interactive display compared to the transflective memory-in-pixel display powering the Vivosport and Vivofit 4. In general, each of these three is lightweight, sleek and very comfortable to wear which are all the attributes of a nice fitness smartband.
