I've just released an update to my Windows Phone app Snotify (click here to find out what it does). The new version will let you set up multiple schedules and specify the days of the week for each schedule. If you set up a schedule that spans two days it'll use the weekday the schedule started on. Optionally you can also let Snotify silence your notifications 0-30 minutes before the actual schedule starts. This can be useful since the background tasks on Windows Phone only run once every thirty minute. But keep in mind that the OS may prevent the task to run at all, so don't depend upon it.

I've just released my latest app; Snotify which is a Windows Phone 7.5 application that silences notification sounds based on a schedule. The application will let you set a schedule to turn off notification sounds once a day. It's the perfect application to keep you from waking up at nights due to emails, text messages or toast notifications.

Changing notification sounds requires write access to the registry. Thanks to Heathcliff74 and his WP7 Root Tools SDK, this is now possible if you have a compartible phone.
