The Fitbit Aria 2 Wi-Fi Smart Scale is an attractive-looking scale that easily pairs with phones and effectively tracks fitness goals. However, compared to other options, it may not be worth the cost unless you’re already a Fitbit user.

Best answer: Nope — anyone can step on the scale and it’ll give you an accurate reading. If you want to keep track of your weight, you’ll need the Fitbit app on your smartphone.

No electronic scale is going to be super accurate at body fat percentage rating, but the Aria 2 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.

I get weighed on a medical grade body composition scale once weekly and the body fat measurement is usually within ~. 1% of my Aria. If you don’t move the scale, after a few weigh-ins it’ll calibrate, and weight is pretty accurate.

“The body fat scales you can buy online are safe and convenient, but they aren’t accurate,” says Dr. Woolcott, who adds that studies on these devices aren’t reliable because they’re tested on a small number of people. “The scales underestimate or overestimate body fat percentage by quite a lot.

Are they accurate? Body fat scales provide a rough estimate of a person’s BFP. However, they are not very accurate. A 2016 study found that the BIA method of measuring body composition is accurate when using standard, published mathematical formulas.

Overall, the Withings Body Plus is the best smart scale. It sports an attractive design, gathers more information than any other scale and presents the data in an easy-to-understand app. Each and every weigh-in appears in the companion Health Mate app automatically, via Wi-Fi or Bluetooth sync.

Korescale readings are only accurate if you have a solid, level floor. If you don’t use this Kore scale with the app, it will only measure your weight.
