  • Great app!

    By Holden97
    Does a perfect job of emulating an HP11c, at least as a scientific calculator (haven’t tried programming yet). Display is clear and easy to read/use on my iPhone 5s. Only two very minor things I wish it had: key clicks with variable loudness (not just on/off) and nicer-looking numbers. But basically it’s terrific.

    I have SCI-11C it will not work on the iOS 11. Which I wish it would. I had to replace it so I got this one & it’s nothing like the SCI-11C. This one freezes in the middle of my problem & then I have to close it & start all over. It is not because I don’t have enough memory either! I never had a problem with my original SCI-11C. I’d score it higher if it would freeze up!
  • Works just like my hp11c

    Looks and feels like my beloved hp11c. Happy to pay the $4.
  • HP11C Calculator App.

    By PhDPhysicist
    I have owned the original HP11C calculator since HP introduced it. Finding an app for my iPhone 4S that emulated it was fantastic. I now have an iPhone 7 and it works perfectly. I use it almost daily when the stand alone device is not near. This app is outstanding and mirrors the original HP calculator perfectly.
  • Great calculator

  • Great

    Unlike some reviewers, I find it a perfect match to my original hardware, that still sits on my desk. Zero issues or concerns.
  • Nice to have

    By 35-year HP 11C user
    This has met my modest needs when the physical calculator isn't handy. Much more reliable than trying to use the native non-RPN calculator on the phone. My only problem is that on the 5s the size is smaller than my fingers are accustomed to, so I mis-key too frequently. I have to be careful.
  • Excellent

    By A1a1a1a1
    On a 6 or 7, it's almost the same size as the original calculator.
  • Love this app

    By Willbilson
    Works just like my good old 11C - which I still have BTW, but much easier to just use the app than dig out the old workhorse. Very happy with it - I got through most of my career plus my CQE exam with the 11C so was happy to discover this app.
  • Love it. Use it.

    Works just like the "real" one. The only thing that would make it cooler is to use 3D Touch to make it feel like the buttons click.
