    This calculator is great. I have compared it to my actual HP 10bii and the answers are the same. I noticed some of the other reviewers mentioned that their answers were off by a couple hundred or thousand dollars. I had this problem when I first downloaded and thought the calculator was trash. But then I noticed that the Payments Per Year (which is visible right under the answer display) was set to 12. I believe the HP 10bii is factory set to 1 Per Year. You can change this setting by selecting the three lines in the upper right-hand corner, clicking Settings, and just typing in 1 for Payments/Year. After I changed this setting, my answers matched exactly. Additionally, make sure your display is set to more than one zero for intermediate calculations. Your answers will be off by a couple cents or dollars if you are rounding up intermediate calculations while working out a problem. You can do this by clicking a number (for example, select the number 4 for four zeros to display) then click the Orange button and then the Equal sign and it’ll display your selected number of zeros. Overall great calculator and the layout is perfect!

    Excellent! Second to none!

    I’ve used this app for quite a while, and I found it to be full of features that you would expect, as well as features you would not expect, such as full amortization tables. This app is very well done.

    Shut up and just buy this financial calculator already

    Don’t waste time on all the others, this is the one. I’ve spent over 30 years working the HP 10 and this is even better and leaves all the other app versions in the dust.
