Big Oops
Crashes on startup, tho I think mine may have lasted 3seconds. Hiring MS coders?drycreekdoug
Hp 45 Update
App now crashes upon start up... Hopefully there's a fix on the way otherwise the app is useless!Mikeconiglio

Update problems
The app crashes after 5 seconds or so. The update ruined it!!!!!Milt Johnston
Well Done
This very realistic simulation of the HP-45 has everything one could ask for in a classic HP calculator simulation. Absolute photo-realism, from the buttons (that actually appear to move and make a nice clicking sound -- a switchable option), to the dead-ringer display, not to mention the on-off switch that uses a swipe to move the switch.
Going far beyond the power of the actual machine, this simulation provides many more functions and capabilities for virtually any computational need. Nice touches, like displaying the value of Lastx, the stack, and the trig mode complete the package.
Another plus: When this reviewer made a suggestion for one area of potential improvement, the developer was very responsive and is including the improvement in a future update. You won't find a better HP-45 simulator than RPN-45 HD.Show lessWebunit1
Beautiful Emulation
I have owned one of these since they first came out, and still have it on my desk at home. Having one in my iPad is like traveling with an old friend. This app emulates the old machine perfectly, and even offers some useful additions.Hp fan for life
Excellent Simulation
Calculator works great just like my original HP-45. Worth the price and brings back memories of using the slide rule before getting my HP-45.headhog70
