Dont buy
If you are looking for a good minecraft building app DONT buy this one. If you want a really good app that works and is not a waste of money buy Mineprints it is $1.99 but it is very helpful and the buildings and houses range from beginner to more advanced real life structures such as Big Ben and the Eiffel Tower (sorry if I misspelled some words) Mineprints will take some time to get used to but once you figure it out it is very helpful.
