The Fitbit Aria 2 Smart Scale

Expert’s Rating: 4 STAR
The Fitbit Aria 2 scales works seamlessly with Fitbit’s dashboard and mobile apps, plus all its activity trackers, such as the Aria, Charge 2 and Ionic. You could use it without the trackers but together they make a great fitness or weight-loss team.

Aria 2 shows less stats than the more expensive Nokia Body Cardio, but everything you need to know at weigh in. It measures weight, Body Fat Percentage and Body Mass Index, and syncs this data wirelessly and automatically to your Fitbit account. If weight loss is one of your fitness goals the Aria 2 is a great tool to combine with your Fitbit activity tracker.

Fitbit might be a market leader in wearable tech but one of its products cannot be worn on the body. If you did, you’d be using it as weights rather than it reading your weight.

The Fitbit Aria 2 is a smart scale that measures your weight, body fat percentage, BMI and lean mass. It wirelessly syncs these stats with your Fitbit Dashboard and mobile apps, and is a great partner for the Fitbit activity trackers.

The Aria 2, you won’t be surprised to learn, replaces the original Aria that was released a few years ago. There aren’t many functional changes to the first Aria. Instead it has been “reengineered for greater accuracy, easy setup and an improved interface”.

Registering and recognising multiple (up to 8) users is easier, and each is given an icon so you can recognise that you have indeed just weighed yourself rather than your weight being recorded for another person. This was possible too with the Aria 1 but is a neater setup with the 2.

The Aria 2 also has improved grip on its feet. Don’t put the scales on carpet as the accuracy will be compromised if the ground isn’t a hard surface. And always weigh yourself in bare feet to allow for the Body Fat and BMI calculations.

There aren’t many tech gadgets that you stand on but the Fitbit Aria 2 is one of them. See our round up of the Best Digital Smart Scales.

Powered by four AA batteries (the scales will tell you when the batteries need replacing) the Aria is certainly one of the most stylish scales available. It is available in chic black or white, topped by 0.3 inches of glass.

The LED display is clear and can be read easily even through blurry just-woke-up eyes. The Aria 2 has a new digital interface, but the main difference to the Aria 1 is the icons for different users, and a wavy logo when it’s doing its calculations.

Your Aria stats sync wirelessly (and privately) to the Fitbit app. You can set a weight goal and monitor your progress in the Fitbit app, and you’ll gain awards and badges as you go.

Body fat percentage is the total mass of fat divided by total body mass; body fat includes essential body fat and storage body fat. For most women, 14-31% is a healthy range. For men it’s closer to 6-24%.

The Aria measures body fat percentage by using a body impedance method. It has four sets of ITO electrodes that shoot a small 180 micro amp current up one leg and down other to measure body impedance.

(Electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied. Body impedance uses a current to ascertain body fat percentage. Pregnant women and people with heart pacemakers shouldn’t use such digital scales.)

No electronic scale is going to be super accurate at body fat percentage rating, but the Aria will give you a decent idea. Because this measurement can be subjective, the Aria’s body fat reading may not match other scales or the results of manual methods such as calipers, says Fitbit.

The esteemed writer Kirk McElhearn, who has been using digital scales for a couple of years, thinks you might get more accurate body fat readings after a shower and light foot towelling as the humidity on feet makes for better contact.

BMI stands for body mass index. It looks at body fat in relation to height and weight and tells you if you’re in the healthy range.
