Only for USA Do not buy this app unless you are familiar with american building standards. Bought app and raised issue over construction types and u values referenced in the app and got told to buy a book for $85 by their support team. Give me my money back please.
Great idea--poor support I purchased back in April. I reported several major flaws, and rcvd replies to my emails. Unfortunately, after one (1) update, none were corrected or addressed. Pretty unusable as it is right now. I was hoping after 4 months, at least the fatal bugs would be fixed. Nope--you cannot delete or edit block loads (have to start from scratch). Copying projects is broken too--most values don't transfer, and you cannot edit the block loads after anyway... back to the "not ready" shelf.
Very good Great app, would give 5 stars if crash problem was corrected
Not practical For out in the field use.
Crashes Crashes too often and the interface is less than intuitive. Again, too little for too much $
Useless Cant start new projects!
