Fitbit Aria 2

Withings Body+

Full-featured

The Fitbit Aria 2 works well with your Fitbit tracker to help paint a better overall picture of your health. It may not measure as much as some of the other smart scales, but what it does measure it measures well. Plus, it syncs flawlessly and recognizes individual users extremely well.

Pros

  • Wi-Fi syncing with your Fitbit app.
  • Supports up to eight users.
  • Keeps your data private from other users.

Cons

  • A bit pricey.
  • Doesn't track as much as some of the competition.

The Withings (Nokia) Body+ is one of the best smart scales money can buy. It measures and displays the important metrics (more than the Aria 2) and it automatically syncs over Wi-Fi, so you don't need your phone on you at the weigh-in.

Cons

  • App isn't the most intuitive.

The breakdown

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 excellent for Fitbit users, it's missing some key smart scale measurements that the Withings Body+ tracks quite well.

Fitbit Aria 2 Withings Body+
Weight Yes Yes
BMI Yes No
Body fat % Yes Yes
Lean mass Yes No
Bone mass No Yes
Muscle mass No Yes
Water weight No Yes

As you can see from the above table, the Body+ just measures more, offering a better total picture of your weight. But just because it measures more doesn't mean it's altogether better — it's just targeted toward a different user.

The Withings Body+ is geared more toward athletes who actually need to track body water percentage and muscle mass (or, I suppose, non-athletes who are just curious). 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 Aria 2's measurements are more than good enough for anyone wanting to track weight loss and progressive fitness, without getting unnecessarily in-depth.

Great for everyone

Fitbit Aria 2

Great for Fitbit tracker users and anyone wanting more in a scale.

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

Great for athletes

Withings Body+

The Body+ offers 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. That being said, it's $30 cheaper than the Aria 2, so it may be altogether more attractive.
