Key Features to Consider Before You Buy
When choosing a smart scale in 2025, here’s what to look for:
1. Metrics Measured
Some scales only provide weight and BMI. Others offer up to 18+ body measurements, including visceral fat, skeletal muscle, and body water percentage.
2. Accuracy
Look for models with clinical or medical validation, especially if you’re using it for health monitoring.
3. App Ecosystem
The app should show trends, compare results over time, and ideally sync with Apple Health, Google Fit, or third-party health apps.
4. User Profiles
If you live with family or roommates, multi-user recognition is a must. Some models auto-recognize different users, while others require app toggling.
5. Battery & Charging
- Rechargeable (like Withings Body Scan): eco-friendly and convenient
- Replaceable batteries: cheaper upfront, less sustainable
6. Connectivity
Most smart scales use Bluetooth; some also offer Wi-Fi, which is ideal if you want to sync data without opening the app every time.
