Conclusion
Fitbit Charge 4 is no doubt a fantastic watch, although looks more like a smartband. The design is decent with added fitness tracking features that makes it a more comprehensive fitness tracker than Charge 3. If you already own Charge 3, I don’t think an upgrade is really necessary. Otherwise, if you have to choose between these two, Charge 4 is a better bargain.
