ANT+ Weight Scale Display is a free app to use with any ANT-compatible device. With it, you can easily check the body composition of your entire family, from infants to adults. Just download it from the Play Store, and you're ready to go.

First, you need to make sure that your device is connected to the internet and that it is set as an ANT+ device in the settings. Next, select the device you want to use with the app. You can choose from your Android device or iPhone. The iPhone version is a little different from the Android version, so we'll explain the differences for you.

Once you have selected the device, you need to start the measurement. If you are using an iPhone, you need to start the measurement with an iPhone. To do that, tap the screen to start the measurement.

Once the measurement is done, you can see the results in the form of a graph. The graph is automatically generated and can be exported to other devices.

If you want to check the body composition of your child, simply select the child you want to check and tap the screen to start the measurement.
