I use it to replace physical calculator as there is more data to be displayed,and you also do not carry another calculator. More than that,you got the full mortgage list for month(if you choose month). It is awesome!
By the way,please be ware that,as I am here in Canada,and the rate here in Canada is half year compounded,which is different from US,so some easy calculator might get the wrong result.
