How to choose
- Pregnancy Mode and BIA Safety. Some smart scales use Bioelectrical Impedance Analysis (BIA), which sends a weak electrical current through the body. For pregnancy, look for scales with a specific pregnancy mode that disables BIA, or consult your doctor before using any BIA scale.
- Accuracy of Weight and Body Composition. During pregnancy, hydration and body composition change rapidly. Choose a scale known for consistent weight readings, as body fat percentages can be less reliable. Look for scales with good reviews for stability and repeatability.
- App Integration and Data Tracking. A good app helps you track weight trends, set goals, and sync with other health apps. Ensure the scale’s app is compatible with your smartphone and offers easy to read charts for monitoring gradual changes.
- Multi User Support and Family Sharing. Pregnancy involves the whole family. Scales that auto recognize multiple users allow your partner to also track their health without manual switching, making it convenient for shared use.
- Display Readability and Stability. A large, backlit display makes reading weight easy, especially when bending down is uncomfortable. Also, a scale with a wide, non slip platform provides stability and safety during pregnancy.
Frequently asked questions
Is it safe to use a smart scale during pregnancy?
Most smart scales that use BIA are considered safe for pregnancy, but it's best to choose a scale with a dedicated pregnancy mode that disables the electrical current. Always consult your healthcare provider if you have concerns or a high risk pregnancy.
Can I use a smart scale to track weight gain during pregnancy?
Yes, smart scales are excellent for tracking weight gain trends. Ensure the scale is accurate and consistent. Many apps also allow you to set pregnancy specific goals and track progress week by week.

High quality smart scales like those from Withings and Garmin are very accurate for weight, typically within 0.2 pounds. Budget models may have slight variations, but they are sufficient for monitoring trends.
