Fitbit has launched a new fitness tracker that aims to offer a more fashion-conscious styling than other wearable tracking devices, with a slimline bangle-style appearance. The Fitbit Alta is a thinner tracker compared to others in the Fitbit range, using a narrow OLED tap display inside a sweat and splashproof stainless steel and elastomer band, but it still retains the same activity tracking capabilities as its stablemates.
