James has previously released Travelnapp, a clever utility that uses you phone's GPS to trigger an alarm when you are approaching your destination on public transport (thus ensuring you don't miss your stop).
YuleTile can be downloaded from the Marketplace. There's a free trial and the full version costs £0.79 / $0.99 / €0.99. 10% of the apps profits will be contributed to the charity Railway Children, which aims to help children living on the streets.
A Christmas wallpaper, ringtone and live tile advent calendar app featuring 25 hand-painted festive images. 10% of the profits from this app will go towards supporting the work of an international children’s charity.
YuleTile allows you to pin an advent calendar tile right onto your home screen and count down the days until Christmas! Each day you will be presented with the day's tile from which you can enter the app, open up the windows and be greeted with 1 of 25 fantastic hand-painted Christmas images. These will be featured on your home screen until it’s time to open the next day’s tile to reveal another image!
And if your phone still isn’t Christmassy enough, YuleTile features various images and music from the app that you can use to get you and your phone into the Christmas spirit!
