"Fantastic app!! I'm an engineer and this app save me a lot of time. Work like a charm. If you're student or professional this app is a MUST. Contain all the necessary Scientific Functions. Thanks a lot!!"
"I, as a teacher of computers, math and physics am lost without it!"
"I think I have tried all of the scientific calculators..., but CustomCalc is the only one I have registered. It works close enough to the HP calculator I have used for many years that I now don't need to carry it"
