• Design


Both the versa 2 and Charge 4 look decent and stylish too. Each of these two is sleek and elegant – attributes of a perfect wearable and fitness tracker. However, the Versa 2 has a more sophisticated design than the Charge 4. Both devices have cases made of aluminum, while corning Gorilla glass mounts their respective screens. However, the Versa 2 at 11mm thick is slimmer than the Charge 4 which makes it sleeker. Although, Charge 4 weighs a little less than the Versa.

A look at the display, while full-color AMOLED powers the display of the Versa 2, monochrome OLED is for the Charge 4. Thus, the Charge 4 is easier to read outdoors, but the Versa 2 display is richer, more interactive and with ambient light available, it can also be read easily outdoors.

So, from the design section, each of these two has got a nice design, but Versa 2 certainly has the upper hand.

• Activity Tracking


Each of these two features the very best of Fitbit fitness tracking technology and as such can track a whole lot of activities which includes,

– Track your heart rate continuously including resting heart rate and heart rate zones which gives you a clear picture of your intensity during training.

– Track your complete sleep cycle which includes REM, deep and light, and time spent in each.

The difference though, is that Charge 4 now has inbuilt GPS just like the ionic which allows you to track outdoor activities such as routes, distance, real-time pace and locations without carrying your phone along. But with the Versa 2, you’ll need to carry your phone along.

– However, the Versa 2 features onscreen workout that coach you through your favorite moves (subscription-based). The Charge 4 lacks this feature.

Moreover, Versa 2 with a microphone that supports Amazon Alexa that enables voice assistant features.
