I had an HP 42S in college. was best calculator I have ever owned, and had used the programmable features in it.

I have used Free42 on Macs and iPhones for years. love it.

Plus42 improves upon it by expanding the display size, suitable for the aspect ratio and size of iPhone screens and Macs

Thank you for the plus hint. Very nice. Worth the price.
