Kel-Is-Healthy,
Works w/latest upgrade
I had been using a different 15c app, but this app-which I already had gotten, I suppose, DOES work with the latest upgrade. I am still getting accustomed to the ‘look.’ It’s a bit shiny-like a brand new HP15C-I can’t remember that far back can you? But I can’t calculate with any other system.
Mostly I have done simple math, but you can’t beat that back arrow key once you are deep into a stack. Speaking of which I have to give a shout out to my brilliant Principles of Finance professor. As we were working in class I said, “Where is the formula?” He said, “You don’t need the formula.” Our agreement had been that I could use my 15c (instead of the calc they suggested) as long as he didn’t have to help me put it into my calculator. All I said was, “I need to see the formula to put in the stack.” The man not only knew the exact page off of the top of his head, but since my 15 C would give ever so slightly different answers than the ‘suggested’ calculator, as he came around to me in the class he would tell me exactly what number I should have. He did all the math in his head while teaching the rest of the class. I couldn’t ask for a better business professor! I learned so much more from him than how to press people’s buttons. Go Cougars!

Best 15C app out there
As well as being affordable, this app seems to properly save the state of the calculator, including programs and registers, when the program is stopped or the IPhone rebooted. The free app and HP’s overpriced official version do not, a disqualifying flaw. Who wants to re-enter their programs whenever their device reboots?
No flashing display after running a program, a silly uncorrected bug in HP’s app. Plus, this one has a well-done portrait mode and an excellent help that includes the full manual. The key clicks sound good and are switchable from within the app. Haptic feedback capability would be nice. Programs seem to run somewhat slower, but that may be eye candy so the “running” display can be displayed for a second or two during program execution. Feels much like the original. Love it.

Five Stars Again
After the app had stopped to work a while ago due to an iOS update, the developers finally delivered a version that work ms again on the latest release of iOS. This is the 2nd best calculator - the best bring my real HP 15C. If you know how to use the original calculator, you will be able to use this app as well. It behaves just like the real deal.
To the developers: Please make sure that the app keeps on working through any future operating system updates.

SierraTech,
64-Bit Support?
This is my go to portable calculator, I own an old HP-45 & 15C but no battery for either so I relied on SCI-15c which was discontinued and went with Vicinno 15c which was updated for iPhone 6 screen. Used it a lot lately to modify a redesign analog FSK modem (along with Excel) and would be lost without it. I hope Vicinno plans to update to 64-bit for iOS 11 or I will have to buy HP app which will be the third time I have purchased. Thank you for keeping HP-15c alive!
Rosenfritz,
It just works - again!
I write a review a while ago, that this just works, and that’s exactly perfect. This is a great emulation of the venerable hp15c.
For quite a while, it would not launch - it would crash on launch. But all is well now. I had several programs I had put into it a while ago, and they are still there and working well!

Favorite 15C Emulator
Have been using for years, it is my favorite 15C Emulator for iOS. Was disappointed when it stopped working entirely after an iOS 13 update. Tried some other emulators again but none are as good as this one was. Thanking the developers for their ongoing development and making a bug fix for this to work again in iOS 13. Salute!!!
R. P. Envy,
Mr RPN
This app works just like it should. It used to be that when someone pulled out their 15C in a meeting I suddenly knew they were a compatriot! But five years ago my beloved calculator stopped working, and I even talked to my HP Rep about getting another (after denial cane bargaining) but he assured me they were a thing of the past even for HP employees. Thank goodness they live on in smart phones!
Jonah Grumby,
They Finally Fixed it
it stopped working beginning with ios13. Couldn’t find a better 15C emulator in the meanwhile. Some of the alternatives had reviews indicating wrong results, so I went to the Apple calculator. Low and behold, after many months Vicinno INC caught up with revisions. Damage already done to their star rating though.
RosannaDana,
Great HP15C Emulator
Before you buy this app ensure you do research and understand the features, complexities and limitations of the HP15C. This emulator is a faithful rendition of the good old vintage HP15C advanced scientific calculator. Those of us who own or have owned the HP15C will appreciate the convenience of having this on the iPhone as a replacement or backup. Recommended.
Spikelucky,
Don‘t get unless you know the specific calculator
I was just looking for a good calculator that works well and has advanced functions.
Now I’m sure this is a great app for people who are used to this particular calculator, but for anyone else it’s just too frustrating to try and figure out how to do even basic math like +-*\
A fair warning that this uses very nonintuitive inputs would have been nice. Or let people try it before having to pay.
I’m a student and have very little money to waste on trying calculator apps.
