Our review sample was the Fitbit Charge 4 Special Edition, which is supplied with two straps: one black silicone, and one reflective woven nylon, which looks a little like tweed, and makes a smart alternative for more formal occasions. The Fitbit Charge 4 Standard Edition is supplied with a robust silicone strap in black, rosewood (a shade of purple) or storm blue/black. The Fitbit Charge 4 has a very similar design to its predecessor in terms of shape and size, with the slim, rectangular face we've come to expect. The device is water resistant to a depth of 50 meters, making it suitable for swimming, showering and sweating, but Fitbit advises taking a moment to dry the band afterwards.

NFC allows you to use the Fitbit Charge 4 for contactless payments through Fitbit Pay, and you can control the Spotify app on your phone via Bluetooth. It also features an altimeter for measuring stairs climbed. †Premium content and features subject to change.The Fitbit Charge 4 has a narrow rectangular case and slim band (Image credit: Future)īuilt-in GPS is a real game-changer for the Fitbit Charge 4, and makes it a viable alternative to dedicated fitness trackers for anyone who enjoys running, cycling and swimming for general fitness, but doesn't need the wealth of data provided by a dedicated Garmin watch or Polar.
