How to choose
Frequently asked questions
How accurate are smart scales compared to medical equipment?
Smart scales provide reliable estimates for tracking trends over time but are generally less precise than clinical DEXA scans used in medical settings. They are best used for monitoring relative changes in your body composition rather than obtaining absolute medical-grade accuracy for diagnosis.
Do I need to have my phone connected to get a reading?
Most scales will display your weight on their screen even if your phone is not connected nearby or is out of range. However, you typically need your phone nearby and Bluetooth enabled to sync the detailed body composition data to the app for tracking.
Can smart scales measure body fat percentage?
Yes, these devices use bioelectrical impedance analysis by sending a small, imperceptible current through your feet. This method estimates body fat percentage based on the resistance the current encounters as it travels through different body tissues.
What is the benefit of WiFi over Bluetooth connectivity?
WiFi allows scales to sync data to the cloud automatically without requiring your phone to be present or the app to be open. Bluetooth usually requires you to have your phone near the scale with the app active for the data to transfer successfully.
Are smart scales safe for people with pacemakers?
Manufacturers generally advise that individuals with implanted medical devices like pacemakers should not use smart scales. The bioelectrical impedance analysis uses electrical currents that could potentially interfere with the operation of a pacemaker or other medical implants.
How often should I weigh myself on a smart scale?
Experts generally recommend weighing yourself once a week at the same time of day for the most consistent long-term data tracking. Daily weigh-ins can be useful for some but may show frustrating fluctuations due to water retention and other factors.
