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."

    I have used this for a few years now. It has replaced my other physical business calculator. This has to be the best calculator I have had. So convenient and reliable. Never had any issues. Thank you for making such a good app.

    My only one calculator for years!!! Constantly improving over the different versions... Please continue!
  • Front screen app!

    By TKoren
    The front screen of your phone is the most valuable real estate and this app has been on my front screen since purchased years ago. Excellent interpretation of the physical calculator, always kept up to date by the developer, and just simply works! If you have any hands on experience with the 10BII, you will not be disappointed.

    By Lenonade900
    Bought on iPad but it doesn't appear to be intuitive on how to install on iPhone. Was anyone able to do this? Any tips? Edit: Thanks! Your instructions worked great
