ANT+ Weight Scale Display displays the body composition readings that are transmitted wirelessly from ANT™ scales.
The app is free to try: test weight and body fat percentage to check communication with the scale.
Once you know it works fine with your scale, you can buy the premium version. The premium version displays all the measured values, as well as export these values to Garmin Connect (all values), Strava (weight), Fitbit (weight and fat percentage), Sporttracks (all values) and TrainingPeaks (weight, percent body fat, muscle mass, BMI, BMR and water percent).

It works with built-in ANT+ chip devices (ANT Radio Service is required) and using ANT+ USB sticks (ANT Radio Service and ANT USB Service are required).

WARNING: Garmin Connect eventually stops working. It is not an app's fault, it is Garmin Connect service. Even if you try to upload an activity within their website in that moment, it will not work. In such case, wait until the service is restored and upload the body composition readings from the History.
