Garmin Index Smart Scale vs. Fitbit Aria 2: Which should you buy?

The breakdown

With the higher price of both of these scales, they're really best suited to folks who are already using fitness trackers from either company. The Garmin Connect app lets you see all of your stats from your Vivo tracker and metrics from the Index scale in one convenient spot, just like the Fitbit app lets you see tracker and Aria 2 measurements in your dashboard.

Basically, if you have a Garmin fitness tracker, go with the Index smart scale. If you have a Fitbit tracker, go with the Aria 2. If you have neither, then carefully consider other options.

In terms of overall feature sets, the Garmin Index smart scale does have the Fitbit Aria 2 beat in terms of the number of metrics it measures. It gives you a deeper look into your overall weight, so if you're an intense athlete, it's the best option in this case (if you can get past the alleged initial syncing issues).

While the Aria 2 may lack certain features, it does focus on the things it does well, which is great syncing, recognizing multiple users well, and being consistent and accurate. It's a smart scale that's better suited to a family home and not for the Olympian in training.
