Livescribe and other companies offer new apps for your smartpen. You can download these from the Livescribe Online Store. Just go to www.livescribe.com/store and browse the apps available.
Some apps are free and others are available for purchase. All apps are designed to work like the built-in apps that come with your smartpen. Visit the store regularly to check for new updates.
After you download a new app, you can use Livescribe Desktop and add it to any smartpen registered to your Livescribe account.
Livescribe Desktop installs all apps. You can find Store apps under the Applications menu. This menu is the first menu item underneath the Main Menu and is available after you install your first Store app.
