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."

  • My staple app

    By Enidrajm
    This is my go-to calculator on the main screen of my phone. As a business guy, I'm constantly calculating loans, investment returns, etc. and I've been able to do away with a separate financial calculator. This is an excellent piece of software and my happiest purchase.
