Fitbit has become synonymous with fitness technology for everyday people with accessible, easy-to-use gadgets that track progress and encourage exercise; the Aria Air is Fitbit's answer to the digital scale, syncing with the Fitbit app and providing Fitbit designed to provide data to a collection of information collected via a smartwatch.

The Aria Air is an attractive Bluetooth scale that measures your weight and calculates your BMI. Although you do not need to have a fitness tracking watch to use the Aria Air, this scale is best intended as a companion device to one of Fitbits. That said, the Aria Air does not have metrics for body fat, muscle mass, bone mass, or water content. Still, it remains one of the best smart scales on the market; read our review of the Fitbit Aria Air here.

The Aria Air retails for $49.95 and is available on Fitbit's website, Amazon, Best Buy, and other stores.

One of the most striking features of the Aria Air is its attractive design. It is minimalist, clean, and fits into any bathroom. It is available in white or black, with rounded corners and a sleek display screen. At 11.8 inches wide, 11.8 inches long, and 1 inch thick, it is slim enough to slide onto a counter, dresser, or under a bed, while still having enough room for anyone of any foot size to stand on the scale.

The scales are made of tempered glass and covered with ABS plastic, which is known for its impact resistance, sturdiness, and rigidity (for reference, it is the material from Lego bricks).

The display is a backlit LED screen that shows weight in pounds, kilograms, or stones. While there is no rounding to the nearest 0.2 pound, as is common with digital scales, I found the scale to be accurate. When I stepped on the scale, the weight was immediately displayed and immediately synced to my Fitbit account.

The Aria Air does not use bioelectrical impedance, so it cannot measure body composition such as body fat or muscle mass. This is an advantage for people with implanted devices such as pacemakers or who are pregnant, but consult your health care provider to be sure.

Setting up the Aria Air was easy even for non-technically oriented people. The first step is to download the Fitbit app if you do not already have it. The app can be downloaded for free from the Apple App Store or the Google Play Store. If you do not yet have a Fitbit account, you will be asked to enter personal information such as date of birth, weight, height, gender, etc.

Next, turn the scale over to find the battery compartment and pull the plastic tab to turn the scale on. You will then need to set up the Aria Air using the Fitbit app; tap the Today tab, then tap your profile picture to set up the device. Instructions to connect to the scale will appear on the screen.

At this point, you can tap the button on the back of the scale to select your preferred unit of measure and switch between kilograms, stones, or pounds.

Weighing yourself is easy. Place the scale on a flat, hard surface. Avoid carpeting as it will interfere with proper measurement. Before stepping on the scale, open the Fitbit app and tap the "Today" tab. Once you step off the scale, your weight will be automatically synced via Bluetooth. Tap "Save" and your weight will be recorded in your Fitbit profile. Your profile stores your previously recorded weight and allows you to view your progress in graphical form.

If someone in your family wishes to use the Aria Air, each user must have a Fitbit account; you can send an invitation from the Fitbit app using their Fitbit profile or email address. My partner found this process to be quick and easy to complete.

The scale requires 3 AAA batteries to power the scale.

The Fitbit app used for the Aria Air is the same one available for any Fitbit device. This makes the scale attractive to those who are already Fitbit technology fans (like me). It's a one-stop shop for tracking your steps, exercise information, and even where to track your food intake and emissions to see how many calories you're taking in and out.

The addition of the scale allows you to see how these habits affect your weight, giving you a clearer picture of your overall success toward your goals. I found this feature very useful because it brings all the abstract data together into a coherent big picture. I found that a week of less sleep interfered with my activity level, made it harder to tolerate snacking, and resulted in a slight weight gain. Fortunately, the Fitbit app has programs to help me stay on track toward my goals with prompts, plans, and personal reports.

The app allows users to set goals for weight, calorie intake and emissions, sleep, and exercise. Having all this information in one place makes it easy to find out what is working and what is not. For example, if you use one of the fitness trackers and also track your sleep, you can see how your activity and sleep patterns affect your weight for that week, month, etc.

There is also a community of Fitbit users to motivate you. Weekly progress emails are sent to your inbox, detailing all metrics and changes from the previous week, including weight changes.

Note that it is possible to manually enter weight into the Fitbit app without the Aria Air scale.

Although the Aria Air is intended to be used with the Fitbit app, it can be linked and connected through Fitbit to a wider range of other apps: MyFitnessPal, Google Fit, Lose It, etc. for the Fitbit family of products, Dozens more apps are supported.

For those who want to enjoy Fitbit's easy-to-use integration in one app, the Aria Air is a solid choice; Fitbit's programming, community, and statistical data logs are excellent tools that can provide motivation and support to keep you working toward your goals.

However, it is worth noting that other digital smart scales can and will automatically sync to the Fitbit app without having to purchase a Fitbit-branded scale. For example, the Renpho scale automatically syncs weight and body fat to your Fitbit profile. This does not require any configuration and appears to be done automatically.

If you have a large family with children and don't mind measuring body composition, the Aria Air is a great choice. Its sturdy construction, sleek design, and ease of use make it a worthwhile purchase if you already own a Fitbit device. Without additional Fitbit products, this scale is not a particularly standout choice.
