App for true carpenters only

Anyone who is not giving this app a five star rating is clueless. The app provides all the necessary angles and information to calculate any hip/valley rafter, length, location, intersection point to construct any roof system. For anyone with a firm grasp on geometry yet lacking an education in trigonometry this app is a must.

Shocking app

This is the worst app ever. Not user friendly at all. Display is horrendous on the iPhone. Can not choose between metric and imperial. Just don’t do it. Save your money

Rafter tools plus

Just brilliant! I agree it’s probably not for everyone - but I found it incredibly intuitive. Helps if you understand trigonometry in the first place.
