We've just had some sales figures from Apple. In the second half of July, 21,089 people installed the Catholic Calendar application for the iPhone and the iPod Touch. That's more than 1,200 downloads per day. People all over the world are using it: there are even 180 downloads in mainland China.
It's nice to be able to do good like this. If you know anyone with an iPhone (or an iPod Touch) then do encourage them to install the Catholic Calendar as well!
The Catholic Calendar can be found in the iPhone App Store, or you can read about it on the Universalis site at:
