WP8 application for replace standard watches on lock screen

Question

Is there a possibility for Windows Phone 8 to write application to replace standard clock on lock screen?

Answer 1

No, an app can only provide the background image, or be one of several apps to provide notifications (icon, #, message--in the bottom area of the screen). One app can provide detailed status, and up to 5 can provide quick status.

The count, text, and icon are defined in the primary application tile (ie the lock screen mirrors the application, if the user lets it). For more detail, see: http://blogs.msdn.com/b/africaapps/archive/2013/06/03/enable-lock-screen-notifications-in-your-wp8-app.aspx
