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."

  • Doesn’t work

    By UF student Michael
    I keep finding issues with this calculator. The PV and FV functions are off, cash flows are off, end and begin mode don’t work properly. Missed many questions because of this app. When using a handheld calculator doing the same functions, you can see what I’m talking about.

    I've always have loved the 10bII, I was even a little sad to shelf the good ole girl for the new iPad/iPhone App version. Wow, what an improvement! The ability of this powerful calculator with the developers worksheets make this a premium calculator. The developer is both responsive and talented. I love having it available at my side on my iPhone, but prefer the robust iPad version, and you get both! My highest recommendations for this app. Developer constantly improves and updates. This app is Highly recommended 👍🏻👍🏻👍🏻😀😀
