Fitbit finally launches a smartwatch in bid to reclaim wearables crown

Long-time wearables king Fitbit has belatedly got into the smartwatch game in a bid to fight back against Apple and Xiaomi.
As you would expect, the Fitbit Ionic comes at the smartwatch category with a distinctly health-and-fitness bias. A prominent feature is an SpO2 (peripheral oxygen saturation) sensor, which can apparently tell how much oxygen there is in your blood. This seems to be the sort of thing health/fitness fanatics like to obsess over so it’s likely to be a crowd-pleaser.
