Does more than the basic calculator and is really nice IMO. It takes a little bit getting use to the keys to operate it but it is very simple in essence. You can even change the theme of the calculator program. Works perfectly on my Pearl. The best part it is free as far as I can see.. From reading the reviews there might be some calculation issues/graphing issues but we'll see.


Any way here it is
