I originally bought this app because I missed designing houses; I owned the gold version of home design 3D well once I updated to 9.3.1 on my iPad it wouldnt even load it and wouldnt allow me to do anything on it because the app wasnt up-to-date and hadnt updated since 2015 which made it out-of-date so after a month of waiting for an update I gave up on it and went searching for a CAD app just as good or better that is up-to-date and I searched and searched and checked out all thoroughly so I didnt have to buy one and realize I didnt like so in doing so I happened upon this app and it is just as good and better than home design 3D and let me tell ya it is up-to-date too and on top of that has smoother movements especially in 3D. Though it costs money it is cheaper than gold home design 3D.
