WHAT USERS SAID:

"A great simulation of the HP-45. Beautifully made, with a lot of attention to small details."

"This is by far the best RPN calculator available for the iPad!"

"This is one of the most accurate but also nicest looking emulators I have come across for the HP-45, or any vintage HP calculator for that matter."

"This is exactly what I've been searching. My HP 45 packed up some time ago. Thank you so much!"

What's New in Version 3.6

• Better FRAC results for large arguments


Bug fix:

• RND didn't round correctly certain values in SCI and ENG mode

Exactly what I was looking for!

:
Having owned the
HP-45 since college, I have been using my original for over 37 years, but with batteries hard to find, I wanted something to use when not at my desk. Since I now carry an I pad with me everywhere, this ap solves that problem!

Would like to see landscape mode with the registers shown on the side.

Great ap that I would recommend to anyone who grew up with an HP-45!
