Quote from a customer:

"Last week I had a meeting with my accountants and my bankers. We were working on the pro forma balance sheets and cash flows for a new project I'm working on.

They were all asking why I had switched to the iPhone for I used to be a die hard "brandX phone" fan. I said that one could do so much more. They said "yea...sure" (they were all using "brandX phones") until I started using your calculator. We were analyzing different payment and amortization schedules. They were so impressed by how easily we could figure out the amount of interest, principal and remaining loan balance for any certain period or combination of periods that in the end they were saying "I have to get me one of those".

 Great product. Thanks."

    Useful app/calculator

    I have a Hewlett-Packard 10BII. This app duplicates the features of that to a T. Perhaps better. Thank you.

    Awesome product

    I’ve been using this calculator for over a decade. It stays updated and is extremely useful and powerful. I primarily use the financial calculator functions. It is quick and easy, and it’s always at my fingertips. I haven’t put batteries in my old HP stand alone calculator in so long that I don’t even know where it is anymore. It really is a great product, both on my phone and my iPad.

    Perfect for CFP exam

    I bought this app almost 10 years ago to help me study for the CFP exam. While you cannot bring your phone into the actual exam I found this app to be very helpful when studying. It is a great display, very easy to look at. I found this app far easier to use than my HP 10 Bii + financial calculator. I use it everyday.

    Business at its best

    Used this calculator since 1992, when I actually bought the device. I love its simplicity and accuracy in business. Some things should always be there and this one just gets better and better.
