Fitbit Charge 3 Overview



  • Comfortable to wear
  • Many useful functions
  • Great display


  • A little overpriced
  • Heart rate monitoring isn’t the most extensive

It’s true that the Fitbit Charge 3 doesn’t deliver a function or doesn’t have a feature that is exclusive to it. However, it takes all those that already exist and packs them into a refined package, with a more sleek design, and more affordability of price relative to the performance it has to deliver.

Fitbit Ionic Overview

Fitbit Ionic


  • The ability to make payments
  • Great display
  • Superb screen resolution
  • 15 built-in sport apps


  • No built-in music storage
  • Doesn’t have a multi-sport mode

The Fitbit Ionic would fit the category of fitness trackers more than smarwatches. It does have online payments and bilt-in GPS, but for the same price tag, you can get another device that offers a lot more. It’s worth mentioning that is has a nice display and a solid battery life, so it’s still a good value for the money.

Design, Display, and Colors

Fitbit Charge 3

The Charge 3 looks a lot like its predecessor: The Charge 2.

The screen is vertical, and the shape and size are pretty much the same as the those of the Charge 2’s.

Its aluminum body and Gorilla Glass 3 that are similar to the of the Versa’s and Ionic’s give it an advantage over the former. Its display is also a splendid touchscreen that supports grayscale colors and not just the black and white colors.

Its screen size is also 40% bigger in area than that of the Charge 2.

You can get the Charge 3 in a woven material in black or blue, or the special edition in a perforated white or lavender sports band for a couple of extra dollars.

Fitbit Ionic

The Fitbit Ionic’s dimension 1.9 x 4 x 8.7 inches and it weighs 1.7 ounces, which isn’t the lightest of fitness trackers. Compromising some of the portability for the sake of the amazing color LCD touchscreen seems reasonable.

Its high-resolution display that reaches up to 1000 nits and is protected by strong Gorilla Glass 3 like the Charge 3.

It shows you the fitness stats you need like calories burned and floors climbed and it has 17 clock faces you can choose from to suit your style best.

Winner: The Fitbit Ionic.

Fitbit Charge 3

Which Is Better The Fitbit Charge 3 or Ionic? Final Words:

Bottom line, From the practical point of view, the Fitbit Charge 3 still performs as strongly as the Charge 2 but with more features and a more solid battery life.

And compared to the Fitbit Ionic, it only lacks a couple of features that may easily be overlooked if your main concern with the tracker is the exercise features but it comes at a quite more affordable price.

The Ionic, on the other hand, may seem a little overpriced seeing the little difference in features, but its stunning display and how big and clear that stats appear on it compensate for the difference in price.
