    it does what it does (emulate HP 15C) without any fuss, and well.

    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!
  • Just like the original!

    Try this on your calculator: (-.5!) then hit or "=". The flashing display means the calculator is executing the wrong algorithm. It should evaluate to the sq. rt. of π. This app has the fine details that made the HP15C a classic. I knocked off one star just because the latest update tends to lock up the first time it's opened. Just restart.
  • 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!
  • Locks up continually now

    Not sure what has gone wrong but the app is no longer reliable. It locks up after just a few operations. This needs desperate attention to run on Apple's latest iOS.
  • Just like daddy's

    Actually, just like the one I packed to work at LLNL for much of my carrier. I still have a couple of them, but this one is just handier. Except for the slight wobble of the keys, this one is identical.
  • Excellent emulation

    I have two Hewlett-Packard Packard HP 15C calculators (hardware), but this emulation has become my go to calculator. Very pleased with this!
