    This calculator is probably the best one out there, I can only imagine the amount of work put into it. I'd just like to report a couple of bugs - the Matrices calculator has a different menu on the right tap than all the others, and the important bug - additional calculators (that you turn on in the settings) don't have the right tap menu at all nor can you turn the action bar on or off by holding

    This is a great calculator app, it does far more than I will ever need. The best thing is the way it simplifies complex calculations. It is very customisable and easy to use, and the help feature covers everything. Well worth paying for.
