Quality app - great graphics – HP 15C Calculator Review

I found this app to be wonderful. At first I was frustrated with it as it would not switch to landscape mode which is were most of the functions become available. Found I had to switch off rotation lock to get the app to work in landscape mode! Love the look of this app, great quality graphics! And I love RPN calculators. Expensive app, but then all HP products are expensive.
