Fitbit Aria Air review

The Aria Air is the simplest scale on this list. It shows your weight on the scale and sends it over Bluetooth to the Google Health app, which calculates BMI from your profile and charts long-term trends. Its main appeal is the ecosystem: weight sits next to the activity, sleep and food data from Fitbit trackers and watches, so you can compare calories in and out in one dashboard. Setup runs through the app, and anyone in the house can use the scale by opening their own Google Health app and stepping on. What it lacks is body composition. There is no body fat, muscle or water reading, so it does not fit this list's audience of people tracking composition as well as weight. Syncing also needs your phone nearby. At $49.95 on the Google Store it costs the same as the Wyze Scale Ultra, which adds Wi-Fi and 13 metrics, so we rank it last.
