And by the way, I love this app! I use it several times every day, it’s my only calculator except for a physical HP 12-C that lives in my briefcase and hardly ever gets used. I’ve been an HP fanboy since the 35, RPN is so pleasant to use. And having it on iOS is the best of both worlds.

Wonderful app! I would love an equally good HP-67 for iPhone. I have it for iPad, but not for my phone. It would be nice if the volume adjustment stayed set rather than needing to be reset each time the app starts.

My favorite calculator app for iPhone. Love it!

Mar 07, 2012 see my old trusty HP-45 calculator in the display of my iPhone. If you weren't using calculators back in the early seventies, you might not appreciate this feeling. Somehow, I miss those light diode displays; they are just somehow cozier than the cold segmented LED's you see in today's $8 calculators stuffed in cardboard display units at the local Best Buy. The developer's HP-45 app for the iPad offers more features - including five magnitudes of faster calculating speed, and it's presentation isn't a bit squished like this app. But the HP-45 was a HAND-held calculator intended for your pocket, and when was the last time you put your iPad in your pocket? Be sure to visit the developer's web site where you'll find a abbreviated manual and lots of facts about the HP-45 and how you can use this calculator to accomplish a surprising amount of calculating. In summary, it isn't very fast (the HP-45 wasn't either), but back in the seventies it was just sort of amazing it existed at all (kind of like today's iPhone and iPad). For a buck, the Vintage-45 is a little side-trip down memory lane, at least for us aging geeks.
