Fitbit Aria vs Aria 2 (2026): What They Were & What to Buy Now
If you’re comparing the Fitbit Aria and Aria 2 smart scales, here’s the key thing to know first: both are discontinued. Fitbit no longer sells the Aria line, so while it’s useful to understand how they differed, anyone shopping today should look at a current smart scale instead. Below is the honest summary, plus our recommended alternative.
How the Aria and Aria 2 compared
Both were Wi-Fi smart scales that measured weight, body fat percentage and BMI and synced to the Fitbit app for up to eight users. The Aria 2 improved on the original with:
- Better weight and body-fat accuracy
- Easier setup (Bluetooth-assisted onboarding)
- Water-resistant feet
- A clearer display with trend info
| Feature | Fitbit Aria | Fitbit Aria 2 |
|---|---|---|
| Metrics | Weight, body fat, BMI | Weight, body fat, BMI |
| Accuracy | Good | Improved |
| Setup | Wi-Fi only | Bluetooth-assisted |
| Status | Discontinued | Discontinued |
So the Aria 2 was the better scale — but that’s a historical verdict now.
What to buy instead in 2026
With the Aria line gone, the strongest current option is the Withings Body Smart: a Wi-Fi/Bluetooth scale that tracks weight and full body composition, syncs to the Withings Health Mate app (and Apple Health), supports multiple users, and runs over a year on batteries.
Withings Body Smart Scale
- ✓Accurate weight and body-composition metrics
- ✓Syncs with Health Mate and Apple Health
- ✓Multi-user with auto-recognition
- ✓Long battery life
- ✕Body-composition uses bioimpedance (see note below)
- ✕App features tier up to a subscription
Health note: smart scales measure body composition using bioimpedance (a small electrical current). If you have a pacemaker or other implanted cardiac device, this is one feature to avoid unless cleared by your doctor — see our guide on wearing a tracker with a pacemaker.
