The number on a regular scale only tells part of the story. When you lose fat and build muscle, your weight may barely change while your body shape improves. Smart scales estimate body fat, muscle and water, and sync everything to an app so you can see trends over time.
Below are popular, widely available smart scales and what each is best for. We have not personally tested these products; picks are based on features, app support and design.
Quick answer
Smart scales use bioelectrical impedance to estimate body composition. The numbers are not precise, but they are useful for tracking trends if you weigh at the same time each day. Choose one with a good app, sync with your health apps and multi-user support. Do not use them if you have a pacemaker or other implanted electronic device.
Smart scales send a tiny, painless electrical current through your feet. Because fat, muscle and water conduct electricity differently, the scale estimates your body composition. Readings can change with hydration, meals, exercise and time of day, so a single reading can be off by several percentage points.
Best practice: weigh first thing in the morning, after using the bathroom, before eating or drinking, and focus on the weekly trend rather than daily numbers.
What to look for
- App quality: clear charts and trends matter more than dozens of metrics.
- Syncing: works with Apple Health, Google Fit, Fitbit or your favourite app.
- Multi-user: recognises different family members automatically.
- Connection: Bluetooth is fine; Wi-Fi syncs without your phone nearby.
- Safety: check manufacturer warnings for pacemakers, implants and pregnancy.
