Fitbit has launched the new charge 5 with a rounded design and a colour screen

Fitbit is officially announcing the Charge 5, the company’s latest fitness tracker, and it marks one of the biggest design changes to the popular Charge family since the first Charge HR, which came out in 2015. The Charge 5 shaves down the hard angles that have defined the Charge trackers for a more rounded look, and more significantly, it’s the first Charge with a color AMOLED display. The Charge 5’s screen is 10 percent larger than the Charge 4’s, and can get up to 450 nits bright, up from the Charge 4’s 200 nits. Like the recently-released Fitbit Luxe, the Charge 5 also has a buttonless design, meaning you’ll interact with the device entirely from the touch screen. The silver rails on the side of the Charge 5 might look like buttons, but they’re actually sensors that let you take electrocardiogram (ECG) readings to check for signs of atrial fibrillation and electrodermal activity (EDA) readings to check your body’s response to stress. The new features and design on the Charge 5 come at an increased cost. The Charge 5, which comes in black, silver, and gold colour variants, costs $179.95.
