If you are using HealthVault and some of its enabled apps, you will want to keep your information synchronized. That is because some apps maintain their own versions of a PHR. There is no standard way to sync; apps handles syncing differently, but often you will find an app using a common method, the Sync with HealthVault button.
In noMoreClipboard you also need to set up syncing then execute the sync by click on the Sync with HealthVault button.
With Heart360, syncing is a piece of cake: it syncs your information every time you access Heart360 via HealthVault.
