Here's an interesting app for your Windows Phone. Appointile generates dual live tiles for your Windows Phone Start Screen that list your appointment agenda. AppoinTile is an ideal app for those who are wanting to see more than just one upcoming appointment on their Start Screen.
When you first launch AppoinTile you are taken through a set-up wizard where you choose which calendar to tie into (Windows Live, Google, etc.), how you want your tile to look (number of appointments, days in advance, etc.) and pinning the tiles to the Start Screen.
AppoinTile allows you to list up to four appointments and will reach out as far as thirty days in advance. The back of the tiles can display the date or a 42 day calendar with markers placed on busy days.
The AppoinTile tiles will sync automatically with their respective calendars on a schedule you set within the app's settings. You can also restrict synchronization to only over Wifi/USB. If you need to change calendars, you can access the calendar settings from the three-dot menu.
If you need a little more information displayed on your Start Screen with regards to appointments, AppoinTile is a Windows Phone app worth considering. There is a ten day trial version available and the full version will run you $2.49. You can grab AppoinTile here at the Windows Phone Marketplace.
