One of the best apps for iOS
Amazing authentic replicate And it just works and it looks phenomenal!
Faithful simulation and super useful calculator
Incredibly well implemented.
Very good, but found a math error
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.

A change in iOS 13 caused numbers to be reduced to 6 significant digits, in vintage mode only. Fixed in version 4.0.
RPN 67-SD
I am an owner and long time user of a real world HP-67 which has some technical problems. Because this was such a fantastic device, I have since been using the iPhone version of the RPN 67-SD. Unfortunately this has also now stopped working. It just started crashing when I opened the app. So I deleted it and re-downloaded it. But now it crashes whilst I am trying to perform calculations.

Version 4.0 had a bug with scientific display format that only affected certain regions – Australia among them – and therefore went undetected for a while. Fixed in version 4.0.1.
