The Fitbit Charge 3 was launched in 2019 and the Charge 4 in 2020. Although they look pretty much identical, the Charge 4 has some additional features that made it well worth for some people to upgrade their device. One of these features is the GPS, which allows you to track all activities such as walks, runs, swims, bike rides and more.


When these devices were first launched they were given the same price range, however the Fitbit Charge 4 is now cheaper than the Charge 3.

Given that the Charge 4 has a number of new features at a cheaper price than the Charge 3, the cost alone makes the Charge 4 the clear winner!


Look-wise both trackers look very similar, though the Fitbit Charge 3 has a case made from aluminum, while the Charge 4’s is made from plastic resin.

Weight-wise the Charge 3 weighs 29 grams, whereas the Charge 4 weighs 30 grams.

Both devices feature Fitbit Pay, however this feature is only available with the Charge 3 special edition, whereas when you buy a Fitbit Charge 4, you get Fitbit Pay even if you have bought the standard version of the device.

The Fitbit Charge 4 has full on-board GPS, which is not available on the Charge 3. However, they both offer automatic workout detection.
Both have heart-rate monitoring and also SpO2 sensor.

Both the Charge 3 and Charge 4 have a mindfulness app that will lead you through a deep breathing exercise if you really feel stressed out.

Fitbit Charge 4 vs Charge 3: Who Is The Winner?

We personally recommend the Fitbit Charge 4 as you get to have an upgraded device at a cheaper price.

They both are outstanding health and fitness trackers which are very similar in look and features, but having the option to use the GPS at no extra cost is definitely something that is nice to have.

On the plus size, you get to use Fitbit Pay even if purchasing the standard Charge 4, rather than having to pay more for a Charge 3 special edition.
