Frequently Asked Questions

What does the Wireless Scale measure?

The Wireless Scale measures your weight and Body Mass Index (BMI). BMI is relative to both your weight and height, and helps you know whether your weight is healthy for your height. It is usually considered that a normal BMI is within 18.5 and 25. Both these data are displayed by the scale and get synced with your app and Withings account.

What is the Position Control™ feature?

Position Control™ is a patent-pending technology developed by Withings. It helps you properly position your body for a high-accuracy weight measurement. Digital scales such as the Wireless Scale usually feature four weight sensors and are calibrated during the production process with a load equally distributed across these sensors. For the weight measurement to reach a high-accuracy level, it is important that your body weight also gets distributed equally across the scale's weight sensors each time you weigh. The Position Control™ feature uses the scale's display to give you a visual feedback on your body position and help you reach this balanced, high-accuracy weighing position.

What is the Wireless Scale's weight limit?

The Wireless Scale's weight limit is 180 kg (396 lb).

Can I use the Wireless Scale if I have a pacemaker?

Yes, the Wireless Scale is absolutely safe to use even if you wear a pacemaker as it does not circulate any electrical current through your body.

What weight units does the Wireless Scale work with?

The Wireless Scale displays weight in kilogram (kg), pound (lb) or stone (st). You can easily switch to the unit of your choice by pressing the unit button underneath the scale.

How do I upload my readings to the app?

You don't need to do a thing. The Wireless Scale will automatically upload your readings as soon as you step off the scale. If you do not have a Wi-Fi network, the scale will connect to your iPhone, iPad or iPod touch in Bluetooth; you just need your iOS device to be in range of the scale (within approximately 20 metres).

Can the Wireless Scale be kept up-to-date with new software?

Yes, Wireless Scale is a smart and updateable device. It can be updated with new software to add new features, make it compatible with new apps or devices, or fix issues that our users have reported. If you have a Wi-Fi network, software update will occur automatically at night as soon as an update is available. If you don't have a Wi-Fi network, the Withings app will advise you when an update is available and provide update instructions.
