The Fitbit Charge 4 includes a few new fitness features that the Charge 3 won’t be getting. Both models are also swimproof up to 50 meters. The Charge 4 makes NFC standard for Fitbit Pay (previously it was limited to the SE model) and also adds built-in GPS, a first for a Fitbit tracker. The Charge 3 already had an array of powerful sensors, and the Charge 4 only builds on it. If you’re coming from a Charge 2, it’ll take some getting used to, but it’s vastly improved over the physical button and tap-screen on the Charge 2. The screen is fully touch-enabled for taps and swipes, and the divot on the left side is actually a haptic inductive button that acts as a shortcut to the settings, dismisses alarms, and activates Fitbit Pay. Navigationįitbit introduced a whole new navigation with the Charge 3, and nothing has changed on the Charge 4.

However, the Charge 4’s screen is slightly more advanced due to better backlighting that adjusts to different lighting conditions. With a very similar body, the Charge 4 also has the exact same high-resolution (100×160) 1-inch greyscale OLED display with the Fitbit logo underneath.

Even with larger dimensions, the Fitbit Charge 4 won’t look or feel much bigger than the Charge 3.
