The breakdown

We're a virtual company made up of tech experts from across the globe. We know scales are for more than just tracking weight — they can be a powerful health tool, and the right smart scale can be huge for your fitness journey. Our top pick is the Withings Body+. The largest difference between the Withings Body+ and the Fitbit Aria 2 is the number of measurements each scale tracks. While the Fitbit Aria 2 is an excellent simple scale for Fitbit users, it's missing some key smart scale measurements that the Withings Body+ tracks quite well.

Weight Yes Yes
BMI Yes Yes
Body fat % Yes Yes
Lean mass Yes No
Bone mass No Yes
Muscle mass No Yes
Water weight No Yes
Number of users it can track eight eight
Pregnancy Tracker No Yes
Baby Mode No Yes
Nutrition Tracking No Yes

As you can see from the above table, the Body+ just measures more, offering a better total picture of your weight. It even gives you the local weather so that you can plan your day.

The Withings Body+ is geared toward need specific measurements such as water weight, bone mass, muscle mass, and nutrition tracking. It's also great for growing families, with the Pregnancy Tracker and Baby Mode. The Fitbit Aria 2 is more of an "everyone" scale. It measures and tracks the aspects of your body that are important for everyday health, like BMI and body fat percentage. The accompanying Withings Health Mate app syncs with over 100 other health apps, including Apple Health, MyFitnessPal, and RunKeeper.

The Aria 2's measurements are more than good enough for anyone wanting to track weight loss and progressive fitness, without getting unnecessarily in-depth. If you already own a Fitbit, you'll already have the Fitbit app you need to use with the scale.

Fitbit Aria 2

Straightforward

Great for Fitbit tracker users

While the Fitbit Aria 2 is missing some major metrics found in the Withings Body+, it doesn't need them to appeal to "regular" Fitbit users. It's simply great for anyone looking to get more fit while tracking a little more than just weight.

More features

In-depth weight tracking

While the Withings Body+ is great for everyone, it truly benefits athletes and fitness fanatics who are looking for more in-depth weight metrics, like muscle mass. Plus, it's $30 cheaper than the Aria 2, so it may be altogether more attractive.
