About this app
This calculator was a technical marvel when Hewlett-Packard released it back in 1976. This was a time when most students and engineers used slide rules to calculate logarithms and square roots. This calculator allowed users to do such calculations with the stroke of a key.
In addition, it was programmable and had magnetic card storage before the first personal computers came out. Pretty remarkable!
This faithful re-creation provides both new and old users with a way to re-live those days. It is still a very useful tool. Even more so now as you can print and share programs and also create charts! Plus sounds and animation.

Amazing. The full look and feel of the original plus new features. If you have ever used the HP67, you need this app! I have some small mostly cosmetic suggestions, but the "Developer contact" email is not working (no such address). My comments are a bit long for here. Help!

Thanks Cliff! I've updated my developer email address on the store listing.

Keys hard to use; only small usable strike area. Better than free version but can't count on a press registering, which is critical for a calculator. Haptic feedback is slightly delayed and too long. With some polish this would be great but it's not good enough for serious use.

Cyrus, the haptic feedback can be turned off it setting. Click the turn over button. You can also choose fill screen for larger button area.Also check the manual '?' button, it talks about some of these things. Should speed the data entry. Unfortunately, different devices have different touch screen sensitivity and not tweakable via the programming

Android is an EXTREMELY POOR LANGUAGE THE WAY GOOGLE implements itI Every app that I've downloaded from the play store turns itself on automatically when I turn on my phone. This makes it necessary to go to Device Settings and set each app individually to Deep Hiberrnation to prevent them from automatically running in the background on your phone - which uses up your battery and slows down your processor! Further, most apps request far too many permissions - which compromises your privacy!

Sorry Peter. I don't think this is my fault? Not sure what I can do to help. There is a version of this on the Apple store if you want the iOS version.
As far as I know the Android version does not run in the background and only runs when in the foreground.
