This sharing screen shows three ways that you can share your BP. If other people (my wife, for instance) are sharing the scale and BP monitor, I can let them see the readings -- or not. I can also send my information to other people with Withings accounts. For example, if I had a personal trainer (yeah, right) I could send my info to him or her. Finally, I can send my BP info to my doctor in a CSV file through email.
