# 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.

Super HP 67

Cette calculatrice m’a accompagné toute ma vie. Je l’utilise encore...
D’avoir le modèle numérique est un super plus.
Elle est parfaitement identique à la « vraie ».
Merci à Fabien FRÄNZ.

Je retrouve ma calculatrice de jeune ingénieur avec laquelle j’ai conduit tant de projets !

What an app !

Great application simulating the legendary HP67. I owned one when I was 23 ! I have incredible memories of this calculator. I literally spent days and nights playing with it. I can still remember recording programs on the little magnetic cards. I lived the noise of the motor running the card through the device ... 😄
Thumbs up to the author of this fantastic app 👍
