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."

  • Use it every day. No Glitches

    This is really much better than the physical HP financial calculators, which I've used for 30 years. I have no relationship w/ the developer, but I think I've purchased all his apps over the last several iPhone iterations. They just work, without glitches, and the buttons on the screen have very visible colors, like the physical calc, but much easier to read (I'm 69, and I have no trouble using this every day). This is really good, has worked flawlessly with every iPhone and iOS (now iOS 12.x.x) and the developer updates before I notice any problems. Really Good!
  • As advertised
