BOUGHT calendar on 01/04/2015. Was also very interesting to read. But now since mindestens1 week no longer usable due to maintenance. Meanwhile, this app does not work even after more than 4 weeks. It appears again and again "maintenance". An e-mail to the offerer Pocketkai was not answered. Although only 0.99 this app cost, they must work and she has also already works. Here's some "lazy". My conclusion: Stay away from buying.
