Fitbit Aria

The Wi-fi-connected Aria looks the business in black or white glass. Once it’s synced to your Fitbit account it streams weight, BMI and fat percentage info directly to it. And it recognises up to eight users, so your stats are safe from prying.

The app is simplistic but good for quick updates, checking that you’re hitting daily goals and inputting calorie info, if that’s your thing.

If you’ve invested in a Fitbit health tracker and want a better idea of your overall health, then the Aria is an ideal option. The combination of activity, weight and fat data builds up a useful health profile. STUFF SAYS ★★★★, The Aria is the easiest way to track your vital statistics
