Excellent App

PocketCas is a powerful app that is also flexible and intuitive. It has an easy-to-use interface, built-in functions that cover anything you could want in a math application, and excellent print and export options. Another plus is that the developer responds promptly to questions and suggestions with personalized answers.

PocketCas delivers what it promises, and I highly recommend it.
