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."
• Update to work around (more)bugs/changes in iOS12.3

So far so good, but....
The layout of the keys is going to take some getting used to. I understand it is supposed to mimic the 10bii, but I never liked their layout either. The blue/violet sub keys look like they should go with the button below, not the button above. Also, the icon is clean, which is nice, but a bit bright. Since I use a fin calculator a lot and keep it on my main page, the icon was a deciding factor in my purchase.
My biggest concern is that the developer keeps updating the app. Out of the available calcs I considered, this one had the longest gap since its last update. The last 10bii I bought stopped being supported and no longer worked with ios 13. Hopefully, I never run into that issue again with any app I paid for.
The only calculator I use
I’ve spent a couple hundred on financial calculators over the years. This one I paid for once and have continued using it through two phone upgrades. I’m the go to guy in the office for financial calculations or just basic math and this is what I use. It is the only one I will use. Thanks team and keep up the great work!
Update*** because I don’t remember how long it’s been since the last one. I still can’t go through my life without this calculator! I use it in business, personal finance, and even flight planning calculations. This is an everyday use usually multiple times per day. Thank you for making a great calculator and continuous updates.
Best HP calc simulator out there
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.
With Family Sharing set up, up to six family members can use this app.
