The intuitive interface is easy for anyone to use, with a simple touchscreen and built-in NFC for use with Fitbit Pay whenever you’re out and about. With 24/7 heart rate monitoring, your Fitbit Charge 4 will recognise when you’re in a period of high intensity exercise and track when you enter peak, cardio, and fat burning stages. You can also track your steps, distance, floors climbed, and calories burned, while also getting reminders throughout the day to keep moving. You can also work on forming better sleeping habits with sleep tracking, silent alarms, and sleep scores.
