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."

  • 10BII Calc

    By jkbutcher
    This became my true friend when I was studying for my CFP exam years ago, it was reassuring to find yes app so I could take it along in my travels. Having a separate calculator is just one more item to carry. Thank for this available, must item for me.

    Even better than the physical 10bII. The Developer Earnie constantly is improving the app which always works flawlessly. He responds to emails quickly. I have had this app for years on both my iPhone and iPad. It’s terrific.

  • Es mejor que la original

    By Fanatico al Waze
    Tengo la calculadora original en mi escritorio; pero prefiero esta mil veces. Mucho mas opciones como la función de conversiones o las hojas de trabajo. Altamente recomendada. Oct 2017. La nueva versión está súper mejorada. Se volvió la única calculadora que yo uso. Abril 2019; la calculadora cada versión trae nuevas características que la hace ser la mas eficiente de las calculadoras. Ya no tengo calculadora de escritorio
  • Love this program

    By Lost in Barca
    I use this virtually everyday. This is so much more than just a replica of a Calculator. What I like are the worksheets that are included that make data entry much easier if you forgotten what to call certain inputs. This is a well-designed program, that should be on everyone's phone, which will help you with all sorts of financial calculations. Encourage your non-financially adept kids to start using a financial calculator.
  • A wonderful and versatile app

    By Mathetes
    I probably only scratch the surface on using the features available in this app, but am never disappointed. All the way from simple math through mortgage and loan amortization to Black-Scholes calculations on options...all are handled, and the documentation tells you how. Then, if you travel internationally, there’s a handy and up-to-date currency converter.
  • Best Tool for CCIM’s

    By Tee Box Tree
    I use this app every day. This is the gold standard for analyzing my own investments and my clients investments. Quick and easy time value of money calculations as well as amortization tables and separating the bad news from the good news.

  • Better than the actual HP calculator

    By jsc789
    I have used the HP calculator for years, but finally switched to this App. One of the great features of the App version is the content of the registers at available at a glance. Also the app writer is constantly improving it with updates. Warning: Once you try the App version you won’t go back.

  • Excellent calculator and then some!!!

    By Joe10297
    Easy to use with exceptional spreadsheets. While I wanted the app for basic PV calculations, the more I explore the features, the more impressed with this valuable tool. As a banker, I always carried my 17b. This app is far superior than the HP calculator and it is always with me!!! 5 stars!!!!
  • Just like my office calculator

    By Riskflex123

  • Best HP calc simulator out there

    By 92%Dew
    Do not hesitate to pay for this app, you won’t be sorry. Since discovering the HP 10B II years ago, I have one in my office, one at work, one in my upstairs “finance” room — and I have one as a backup. I’m a Type A, sorry. I find I use this one more often than any others for several reasons. It’s absolutely accurate in look, feel and calculations. Add to that, it includes built-in help and examples when I forget a particular formula, no need to carry any of my HP workbooks. It’s been awesome, totally worth the money I paid, you won’t regret it.
  • Excellent!

    By missyp8
    So convenient and works just like my original. Wouldn’t be without it. Love the tape feature. Very useful!! One of the best purchases I’ve made. Use it everyday!

    I use this calculator everyday. I am in a business that requires me to do financial analysis of businesses and Real Estate. I love this calculator. Better than HP 10B II stand alone. Work sheets and tape are very useful. I have been using this calculator for about 7 years now. Thank you for a great product and for the very important updates to keep it top notch.

    By njhuygv
    Without a doubt the best calculator I have ever owned.
  • Much Easier Than Old Calculator

    By Musicole
    This app makes it so much easier to see what you have entered already, which helps ensure your final calculations are accurate. Much easier than the old school style calculator! There’s another app that provides full amortisation schedules, which I haven’t been able to produce on this one yet.
  • Long time happy user

    By Neilsson
    I have used this wonderful app for many years now. I’m an engineer private practice, and everything I need is right here. The alternate calculators are perfect. Rarely needed now, but if I get stuck, the instructions are right there.
  • Love this app

    I’ve used this calculator version for over 15 years. So when I found the app I was thrilled.
