# Iconic
The Legendary 67 revives the spirit of the indeed legendary hp67, one of the first handheld, scientific and programmable calculators.

# Powerful
Calculations are done step-by-step using reverse Polish notation (RPN), which is very similar to calculating with pen and paper. This gives you full control and lets you spot mistakes early rather than later. In addition it is much simpler than using an algebraic calculator while using less keystrokes all at the same time. Last but not least, RPN makes it super easy to create your own programs.

# Programmable
Creating programs is exactly like using the calculator, so there is no need to learn any programming language. Simply put the calculator just records exactly the keys you typed and can replay them on demand. Through a small set of nifty features, like conditions, subroutines and flags a vast set of powerful programs is possible. You can program everything from simple snippets like the Pythagorean theorem, implement matrix algebra and even create games.

# Batteries included
The calculator comes equipped with a handful of useful programs and you can easily create your own. Each program is stored on a virtual magnetic card, with fully customisable labels and descriptions.

# Free
Now the best part, the app is completely free and does not include any advertisements.

PowerWizard ,

Thanks for Hp 67 app!

As an old engineer I loved this calculator. When mine died (the rubber mag strip drive wheel got gummy) I moved up to the Hp 48 which was cumbersome to program. I missed the simple keystroke programability of the 67 which I knew so well. It looks like I can resurrect my old 67 programs and run them again. I sincerely appreciate you writing this app and offering it for the free price. You are a true hero to the HP calculator legacy. I am very grateful to you. Thanks again.👍

Really nice emulator

The days when I would carry my HP-67 around are over, but with this and my phone I can use it again! Thanks for a wonderful app.

Great job!

You made an old engineer very happy. The only thing I really miss is the great key feel. I loved my HP-67 dearly.
