Fitbit Charge 5

The fifth iteration of the Fitbit Charge is less angular than its predecessor, and has introduced a stainless-steel case to proceedings, but the real visible change is in the screen quality: an always-on colour AMOLED touch display, which only the brand’s pricier models have boasted before this point. Beyond that, it’s added plenty of cool health apps like the electrodermal activity (EDA) sensor, which reports levels of stress, as well as the electrocardiogram (ECG) app, which checks for irregular heart rhythm. As a fitness tracker, it’s up there with the very best.
