IFTTT is a service that lets you create powerful connections with one simple statement — if this then that. Using a very simple interface, it lets you create “applets,” that let you, for example, program your scale to save your weight in a Google Sheet or have your blood pressure results sent automatically to your doctor. You can browse the dozens of applets already created by IFTTT users or create your own. 

Connecting the Withings App to IFTTT enables you to export weight data, blood pressure measurements, steps, calories burned and sleep duration recorded by scales, watches, blood pressure monitors, and sleep trackers. To do so, search for "Withings" in the IFTTT app and select your device.
