Just like the real thing. I got one of these in 1978 and discovered RPN. I have never used anything but RPN calculators since. I agree that the audible key clicks can be annoying, but I usually keep the sound turned off on my iPad anyway. This is a great emulation of my long dead HP67.

Hp67 review update. I contacted Cuvée and they returned my e-mail promptly, explaining the difference between setting the number of decimal places between the HP 67 and HP 45, which I was used to. They also explained how to clear the statistical registers. Based on their help, I can say that this is a very good emulator and, if you are used to RPN, and want a simple, straight forward scientific calculator, this one is hard to beat, especially for the price.

First Class. What an application! Perfect visual experience, perfect emulation, even the clicks are pleasant. I'll be buying the Pro version for sure. This has to be the most underrated developer in the IOS world. Had only two minor suggestions: The h reg function to display registers zips through too fast (I realise it is redundant), and the legends on the lower surfaces of the lower keys are barely visible. Could you also display the back label? Also, a version for OSX is sorely needed.

Annoying clicking sounds. This is a beautifully written tribute to the original, that almost perfectly follows every function. So why does it make an annoying noise whenever you touch a key? Is this a plot from TI? Seriously, who would ever want this? It stinks! Please add the option to turn off the "clicking" sounds.

amazing. it just works and brings back the 70s - very impressive how much was possible and is again on this little machine! this app is well maintained and up-to date.

Key Clicks. Some people like the clicking sounds; I count myself as one of them. It tells me that the key I pressed performed its function. If you had looked in the app's settings, you would have found that the key clicks can be set to medium, high, and OFF. Before you complain about something, it pays to take a little time and actually learn about the app.

Impressive. This is a virtual HP67 which is very nice and quite special compared to the many generic RPN apps now available. Note that the Pro version allows access to about every program PAC that was made for this calculator. Because I used an HP41C when I was younger it was a pleasure to be able to enter data without needing to examine the keyboard each time.

Nostalgia!. I bought a HP67 as an engineering student in 1979. I remember it cost a fortune and I was so excited to get it home and start using it. It saw me through the rest of the course and was invaluable to me. This app brings back so many memories. I would like to load the civil engineering pack, which I later added to my original calculator, but loading the extra cards from the developer's website needs a Ph.D. in astro physics and a Mac computer apparently. This needs to be simplified so the program cards can be imported directly into the app. Anyway, not bad overall for what, in reality, is just a few dollars.

Another work of art. Those who grew up enjoying the evolution of HP calculators no doubt loved them as much as I did. Along with their superior physical attributes as well as the lovely RPN, the old HP calculators are still my preferred device. Willy has again outdone himself in the realism he brings to this latest addition to his collection. Highly recommended. Graeme

Can’t hand out less than one star, unfortunately. Ohhh, that hurts. The desecration of a great calculator.

Very nice. Very nice retro HP calculator!
