Ratings and Reviews
Simply the Best Financial Calculator (and more)
I just found this marvelous emulation if my beloved HP17BII+ and it's better -- much better-- than the real one! For those who are unfamiliar, the greatest feature of The HP17 Is the ability to write equations and have the calculator solve for any single missing variable. You can store tons of equations and they are much easier to type on the iPhone keyboard. I use it for many specialty functions in my manufacturing business including pricing of complicated custom made items. The HP17 is far superior to the HP12C (though it doesn't have the nifty key layout) and this version is far superior to the real thing. I use it several times an hour all day every day. Thank You for this!
I love this app - just as I loved the real thing for so many years. There is one thing that would cause me to add a fifth star to my rating - haptic feedback. It’s difficult - if not impossible - to really know if a button really got pressed as it is on a real calculator. When I’m entering numbers I’m concentrating on the keyboard and not in the display so I often don’t notice that I didn’t click in exactly the right place.
I have my phone linked to my hearing aids by Bluetooth for phone calls so even though I have the click volume turned to the maximum the sound isn’t audible.
Most configurable calc out there
This app has a number of great standard functions (Time Value of Money, etc) but the Solver emulation is what sold me, and what I used extensively back when I had the HP hardware. Simply create your own equation with your variables, enter your variables and values and it will solve for the one value that is missing! And you can save as many of your own formulas as you like. I used it for figuring weights or lengths on roll goods but you can adapt it your own needs/profession. One of the most user-friendly calc apps imo.
With Family Sharing set up, up to six family members can use this app.
