HP67 Calculator 2.0

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!

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.

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!

There are no ads but I did get the paid version so I could save programs. I think the keys could work a bit more reliabily.

Very good simulation. I would like to know how can I reuse a card. For example, if I write a program and later I modify it, I don't see a way to use the same card. Apparently I have to label a new one and save the program. It would be nice to reuse the same card so it's not necessary to write the labels again. Thanks.

Excellent emulator! Used a real one many years ago. The old manual was well understandable and very clear too. Many thanks.

This app is great! Exactly like using my old HP67 (except my card reader gave up the ghost decades ago)!

I'll gladly pay to get the free version back! Pay version takes way too long to open (Unity screen)! No more vibrate on keystrokes! Back key doesn't exit there app. I only upgraded because they broke the free version. I do love the app, but not this version.

I like the new app and I did not mind paying for it. However, I much preferred the vibrate on keystrokes. Thanks.
