Automatically sync your weight to the WW® app if you are a subscriber, or sync your weight, BMI and body fat measurements to Apple Health and allow your favorite health and fitness apps to access your data and make tracking quick and easy! Our scales allow up to 9 users to measure and display: - Weight - Body fat in % - Body water (hydration) in % - Muscle Mass in % - Bone mass in % - Body Mass Index (BMI) Simply open the app, tap “Connect to Scale” and step on – the scale syncs all data to your app and you can review by day, by week, by month or by year. Having all your measurement results at your fingertips helps make it easier to get where you want to be! iOS 13 Warning: We are aware of an issue where users upgrading from iOS 12 to iOS 13 are losing access to their historical data in the WW Body Analysis Scale Tracker app. Our team is working quickly to resolve this issue for all users. In the meantime, we've added a new feature in release 2.0 that will allow you to export your data from the app to a spreadsheet. To access this feature click the chart icon in the top left of the Dashboard to access the 'Readings' screen with your historical data. From there, tap 'Export' in the top right of your screen. We recommend that any users who want to upgrade to iOS 13 first export their data with this feature prior to upgrading.
