Calendar Live is a simple app to show the next five calendar appointments on a single wide start tile, or 12 appointments on a large tile. Which calendars to display is selectable from within the app and the tile is automatically updated.
The app itself shows a larger list of upcoming appointments, however the main purpose is to provide the start tile.
Please be aware that the app does not interact with the calendar, for example to create new appointments or delete old ones. Its purpose is purely to provide a start tile showing more appointments than are possible with the standard Calendar tile.
