Advent Apollo is a Apollo Mission themed advent calendar.
-Nice & easy Interface
-quality photos

-Limited features
-only displays a photo a day

$0.99 [iTunes Link]

The application only allows you to view photos from the current day or the previous days. In other words… no cheating.

While the application has a nice and easy to use interface, we do not see much use for it. Many of these photos are widely available online with a simple Google search. But if you’re not much into searching, then you might enjoy the nice photos.
