    This app won’t work with ios11 which is what I have.... it’s been warning of this for a long time. What are you waiting for? We paid a lot of $ for this app!
  • Thanks HP for updating for iOS 11

    I have been using this calculator for years since I am hooked on RPN, and I was afraid that it was going to be neglected and made obsolete with the change to the 64 bit app requirement for iOS 11. Fortunately, HP stepped up and updated this app. In addition to the ability to run on iOS 11, they also made the key clicks quieter which is nice since they were obnoxiously loud before.
  • Yes! Updated for iOS 11 64 bit

    I was concerned the app would fail when iOS 11 stopped supporting 32 bit apps but today the app upgraded to 64 bit!!!!! Also the click is softer!!!! It is a much better experience now!!! I'm looking be my HP12-C and this app keeps the next best thing handy! Don't forget to use it landscape to get the full calculator. In portrait it becomes a simple interface. Great job devs!!!!
