    I'm a long time 15c user and Found this app which looked good. I just downloaded it and it does not work. I touch the keys and nothing. Very frustrated and I would like a refund.

    I've been using an hp15c for umpteen years as an engineer and was looking to purchase a used replacement. By serendipity I happened upon the hp12c for iPad/iPhone which I bought for my wife (yes, she loves it!). This iPad/iPhone hp15c gives me all the original did plus more. One thing, I wish it had a full screen mode.
  • Dynamite 15C!!

    This is an excellent version of the 15C! I have both this HD version and the iPhone version and have no problem paying for both for this magnificent, extremely popular 32 year old calculator. In order to use this calculator you must press the "on" button -- earlier reviewers mentioned they couldn't get anything to display and it's because of this. There is full access to the 15C manual. The look and feel of this iPad calculator is excellent as it brings IOS and the vintage HP look together. I was able to load one of my decimal to binary conversion programs into the registers and it works just as the real 15C does.

    Don't buy this app and save some $ Money and buy the HP for $5 more. You will be glad you did. I purchased this app the other night hoping to figure out some problems, I wanted the HP one, but saw this for $5 cheaper and thought ok this should work... I read the details. Then after installing nothing would appear after keying in Anything. I went ahead and bought the HP version and No Issues. I guess you get what you pay for. Instead of getting a workable app for $9.99 or $14.99 I had to pay $24.98, due to this product Not Working! I will only change this review, if I receive a full refund and a proven fix!

    Nothing shows up in the numbers area. I click the numbers and here the click but nothing displays. 10 bucks wasted!

    I bought one in 1984 to do my engineering work, and now use this emulation of the best calculator ever. RPN will live forever now!
  • Great RPN calculator

    The best rpn calculator I have found for the iPad or iPhone. For the price, it would be nice if the developer made this a single app for both device
  • Don't buy this one

    Unlike virtually every other app where there is both an iPad and and iPhone version and you get them on both devices this one does not. If you want to use it on your iPhone buy the iPhone app not this one. At $9.99 you should get it on both. Even Numbers shows up on both. Pretty cheap of this developer.

    It is one of the best apps I have purchased for my Apple products. Aside from apps to read the WSJ and USA Today, my most used apps are the 15C calculator and MotionX products.
  • One of the BEST apps out there!

    I purchased this app -- The Vicinno Soft HP 15C -- many months ago for my iPad1 running iOS 3.2. It has performed flawlessly and truly feels like my real life HP 15C, except that the programming functions and options are MUCH stronger for this Vicinno Soft app.. I own many RPN calculators (8) for my iPad1. I really only use 2 of them for real-life use in my Critical Care Medicine/Cardiology practise. This one and an i41CX+. This HP 15C emulator takes me all the way back to my undergraduate days, and makes me feel great to reminisce about that singular moment when I learned about RPN. When I discovered that I could complete complex formulae and NEVER have to use a (parenthetical) or [bracketed] entry again, AND I could begin formula entry at the deepest segment and work my way out of it, or proceed as usual through the equation ... Working with complex formulae and programming was never the same! It was an epiphany moment in my studies, and I still refuse to use anything other than an RPN scientific calculator. The Vicinno Soft HP 15C is simply one of the best out there. Don't waste your time looking for a top-shelf RPN Scientific Calculator, this one will do everything you want it to, and more!
