Microsoft have just announced the latest set of updates to the Microsoft Band. You can now share the results of your activity (workout, run, sleep etc) via Facebook, Twitter, email or text message. It works by sharing a summary of your activity with a link to your public facing dashboard.
Also in the update is a new Tournament Mode for Golf and guided workouts now track your distance travelled even with GPS switched off (using the pedometer).
Microsoft doesn’t explicitly say how the update will show up but it will probably be in the form of an update to the Microsoft Health app. You can read more about the changes on the Microsoft blog.
