This app stinks!

Played around for several minutes after download...area pitch, and slopes for simple triangles are incorrect some of the time. Was hoping for an inexpensive construction calc for students. This is not it. Waste of my $15!

Does not work good

Trying to put in degree of bevel and run then does not give rise or slope. They are both 0. I bought thinking this would work like jobber but it does not

Works pretty much the same as the jobber 6

The app works good so far.I've been using the jobber 5 and 6's at our shop for about 11 years now and I love it. I have an iPhone 6 and the screen is about the exact size of the actual jobbers. I wish the app had an option to show fractions above the 1-15 numbers like the jobber 5 has....makes it easier to use and also when explaining to new crew how we use them.
