The calculations are accurate but when zooming in on the diagram it is extremely difficult to see and there's no way to full screen the diagram. I was hoping that sending it to my email or printing it out would make it more eligible, it doesn't, in fact they remove the function to zoom when sent through email. What good are the calculations if you can't see them?.

After watching many youtube vids, everyone has a different method to calculate dimensions, and they all come up with different values which left me guessing. This app takes the guessing out of the equation! It's easy to plug in your info, and the amount of detail you get is awesome. If I were a carpenter or did this work more often, i would definetly buy this app!!

This is a robbery. If they had given people the opportunity to test all the apps' functionality, I swear I wouldn't pay for the Pro version. The 3D doesn't work, the support leaves something to be desired, it even seems like they are trying to guess the solutions. After complaining, they gave me a URL to open the apps in the Browser. Believe me, it doesn't work. Sometimes it opens, sometimes it doesn't. And it's slow as hell. Developers of this app, listen carefully, do you know how much 1
