If you are using Fitbit watches or wristbands and tracking results on the Fitbit app, it’s a natural next step to purchase a smart scale and start syncing your weight and BMI too. Getting everything into one fitness tracking ecosystem is exciting for the data-hungry fitness freak. Now, you’ll be happy to know that Fitbit actually manufacture their own smart scale, the Fitbit Aria. But don’t jump to any conclusions – it’s not your only option as there are actually other cheaper smart scales that also work with Fitbit.

About Fitbit

Fitbit is the market leader for activity trackers and wearable technology for fitness tracking. Users of Fitbit have the ability to log their food intake, weight, quality of sleep and of course track activities. They can also use Fitbit to set daily and weekly goals for themselves. In addition to their range of activity trackers, Fitbit also have a website and mobile app for iOS, Android and Windows 10 mobile. FitBit is headquartered in San Francisco.

Features to compare in a smart scale

Not all smart scales are the same. The vary in functionality and in price. These are some important factors to consider:

What do you want to measure – do you just want to measure your weight and BMI or are you interested in advanced metrics like body fat percentage, body mass, and lean mass?

Connectivity – do you want a smart scale that uses Bluetooth to send data directly to your phone or do you want a Wifi enabled smart scale that requires a good internet connection in the bathroom. Bluetooth is easier to set up but you need to ensure the scale is compatible with your phone. Wifi smart scales work by sending data to the cloud which in turns updates your fitness app. You would need to have  a good connection in your bathroom.

Price – obviously you want something in your budget. If you are going for a scale with advanced metrics you will definitely pay more.

Other features – there are smart scales with all kinds of unique functionality. They are scales that show trends, display smiley faces with your weight (assuming you’ve made progress), athlete modes, and even modes specific for pregnant women.

3 Smart scales compatible with Fitbit

Just to clarify, by ‘compatible with Fitbit’ this essentially means that these smart scales have ‘native apps’ that can integrate with the Fitbit app. So the smart scales basically send data to their native app which then send the data to Fitbit. The result is the same whether you use a 3rd party scale and app or you use the Fitbit Aria which would send data directly to the Fitbit app.

Fitbit Aria 2
