Here's the information you'll get about your Withings account on your Apple Watch:

• Activity: daily data, current week data and previous week data.
• Sleep: daily data, current week data and previous week data.
• Weight: Latest weight value and weight graph.
• Blood pressure: latest blood pressure measurement and blood pressure graph.
• Possibility to launch a blood pressure measurement from the Apple Watch.

A few words of cautions:

• If you're not logged in to the app on your iPhone, your Apple Watch will prompt you to do so.
• The activity, sleep, weight and blood pressure screens only appear on your Apple Watch if you have a device that can measure these metrics.

Note that there are also glance screens available for the Withings App app. They show the last measurement of each screen.
