I used a HP-67 for years and loved it. This app makes me feel at home. However, I recently found a small, but significant math error. With the display set to 2 decimal places, enter the number 28,361.48. When entered, the number rounds to 28,361.50. I was doing a financial calc and this was the error. Update! Problem fixed! The Developer said it was caused by a precision change in IOS.
Excellent simulation of the calculator I had in college. Wish there was a Hp 97 version for the iPhone.
Good replica of 67. I have one issue that could be quickly solved. When I press the f or g key and then the display key, and enter a 4, the number of digits does not change from 2 to 4 and I would be happy.
This was my first scientific calculator in real life. It is great to have the simulator on my iPhone. The special features added make it into a HP-41 or 42S! It comes packaged with some great samples. Am having great fun with it.
My first HP calculator was an HP 29. A few years later, I got an HP 67. Later I bought a 15C and when I started an MBA program i got a 12c. It means a lot to have a really faithful representation of my old friend. I currently have this emulator plus a 12c and 15c (from different a vendor) on my iPhone. I love them all. Take it from somebody who know, all the emulators replicate their real world counterparts.
This version permits you to use your virtual HP-67 just as you could the original - hand held and highly portable. Congratulations to the developer for providing such an excellent and aesthetically pleasing software product. Mike Bredimus RF Systems Engineer, Fellow (Ret.) San Diego, CA
The HP 67 was my second HP calculator. I got it right out of college and used it heavily at work. It has long since demised. This is such s faithful replication. I really love it. It seems to be accurate and the next best thing to having a physical calculator in your hand. Thanks to the author for this product.
