Publisher Description
RPN 28x Calc is a programmable scientific calculator with a pleasingly classic look. Despite its nostalgic appearance, it offers a modern and intuitive user experience, allowing you to interact with your operands by touching them in the display.
It is a reverse-polish notation (RPN) calculator with a dynamic stack display. As you add more values to the stack, the display shown on an iPad automatically expands. To see more lines, simply swipe to scroll. You can also re-order the levels or modify any of the values on the stack.

"It’s the third RPN calculator I buy for my iPad 2 and the first that makes me happy.
It’s graphically appealing, intuitive and very responsive. I rated it 5 stars."
(Nuno Gomes)

Advanced commands are available in a secondary panel on iPad or as alternative button pages on iPhone. The buttons are efficiently grouped into five pages that you can quickly access by swiping left or right:
- user-defined buttons,
- letters A-Z for typing,
- trigonometric, logarithmic, and data manipulation commands,
- statistics, storage and programming commands
- binary integers, system flags and boolean logic.
This is why RPN 28x Calc is unique in its class:
- You can tap a row to select it and issue commands for the selected level.
- In REORD mode, it is possible to rearrange the stack by dragging the rows.
- You can swipe up or down the display to see all levels.
- When you enter a value, you can tap a digit to reposition the cursor.
- Tap on the status indicators in the top of the display to change their state.
- Drag buttons to re-arrange them as you like it (enable that in the settings).
Additionally, on iPad:
- The display automatically resizes to show more than just 4 levels of the stack.
- You can slide the secondary panel out of view or swipe across the panel to navigate between button pages.
