Ratings and Reviews
I wish I’d found it sooner!
This is a wonderful simulation and has become the go-to calculator on both my iPhone and iPad. If I had found it years ago I might have saved myself a fair bit of money and time spent on other calculator apps.
If you like to use RPN calculators and keystroke programming, this one deserves your attention.
Pros - it’s a calculator first and foremost. There is no CAS or graphing to bloat the app. The stack and program listing windows make keeping track of things very easy. It looks good and the settings are straightforward and useful (thank you for allowing the option to mute the key sounds).
Cons - none so far.
Old HP-25 user
I’m very impressed with this program. With the latest update I’m starting to like this app as much as the original calculator. If only the keyboard was the same...
Great app!
This is a wonderful app. Completely replicates the HP 25 RPN scientific calculator with full fidelity.
