Best Smart Scales for 2025 — Guide & Top Picks
A smart scale does more than show your weight. It measures body fat, muscle mass, water percentage and more, then syncs data to your phone so you can track trends over time. The right scale provides insights and helps you stay consistent — but choose features that fit your routine.

Smart scale safety
Weighing yourself can be helpful, but avoid defining self-worth by the number. Muscle can increase weight even as you get leaner. Some scales provide extra metrics (like visceral fat) that give a fuller picture. Dr. Anne Swift (University of Cambridge) warns that frequent weighing may cause fixation on small daily fluctuations; focus on trends, how clothes fit, and how you feel.
Research is mixed: a 2016 meta-analysis suggested potential negative psychological effects from self-weighing, while a 2018 study found regular weigh-ins may help with weight loss. Be careful and patient — change takes time.
What to look for in a smart scale
- Weight: Clinical scales are more accurate; use trends rather than single readings.
- Connectivity: Bluetooth scales may require your phone nearby; Wi‑Fi models upload data to the cloud. Check security and privacy.
- Bone density: Some scales estimate bone mass via bioelectrical impedance.
- Body fat & muscle mass: Look for BIA-based body composition and athlete modes for more tailored readings.
- BMI: Common but imperfect. Useful in clinical contexts but often misleading for individuals.
- Advanced metrics: Some high-end scales offer Pulse Wave Velocity (arterial stiffness), segmental body composition, ECG or neuropathy screening.
- Wearables & integration: Check compatibility with Apple Health, Fitbit, Garmin and other platforms.
- Display: Choose a clear, high-contrast display if you’ll weigh yourself without glasses.
- App & subscriptions: Test the companion app — premium subscriptions may add insights and coaching.
- Data portability: Export to CSV is common; importing varies by platform.
- Power: Battery type (disposable vs built-in) affects cost and lifespan.

Multi-user support: Most scales identify users by weight range and measurements; apps let you set up profiles and confirm matches when ambiguous.
