CalAdvent for iOS

Countdown to Christmas or any other date you want with this app. By default the app is configured for your Advent Calendar needs, but the end date, number of days and themes can be changed to match your countdown needs. For up to 31 days before the target date, one ornament will be unlocked a day allowing it to be placed on the tree/display. You can admire or rearrange the ornaments at anytime. You can even shake the device to trigger a celebration that can change the countdown scene into a snow globe.

This application can use custom themes created with CalAdvent Plus (which is only available in the U.S.) and comes with the built-in Theme Packs: Grandma, Nativity Scene, Easter, Emoji, Halloween; and the Display Themes: 8-bit Tree and 16-bit Tree. More themes will be coming in future updates.
