Calculator Sci app for iPhone and iPad

Immediate, intuitive and functional.
Finally a great design for a Scientific Calculator.

The goal was to create the first calculator on the App Store that do not confuse the user with lots of buttons, without renouncing to their functionality.
How?

- Buttons are big and organized intelligently, using colors to rank them, and easy to read icons.

- There is no shift button: to access the second function of a button, just keep in pressed.

- Clean appearance and nice colors, choose between your favorites.


Not just buttons, we wanted to make the best experience of a Scientific Calculator ever:

- Every number in the calculation is at the same scale of the others.

- The calculation is zoomable, draggable, and you can tap to insert the cursor where you want.

- To move the cursor around there are no arrow buttons: just tap on the calculation or start swiping over the buttons, a blur effect will indicate that you are controlling the cursor like a joystick.

- Chronology! Yes, you can save any calculation automatically in the chronology and filter it with favorites.

- Physics constants: you can access a catalog of 40 well organized constants to insert them in the calculation.

- Save values in another catalog in alphabetical variables.

- Undo / Redo buttons! If you delete by mistake your calculation you can restore it with the Undo button.

- Works great in any screen size, it will adapts to your screen, also in the new iPadOS 16 Satge Manager.

- Scientific and Engineering notations

- Hidden feature: if you are in scientific notation, you can swipe over the result to move the decimal separator and change order of magnitude!
