Programming not currently working
Wasted 3$ on this app. Programming is full of problems like GTO addresses that come up incorrectly. Don’t buy ! Not till it’s fixed anyway!
Description
RPN-25 CE is a photo-realistic simulation of Hewlett-Packard's highly popular scientific calculator HP-25 for the iPhone. Produced from August 1975 through 1978, it was the "Squash" member of the second-generation HP calculators known as the "Woodstock" series.
It was also the first programmable calculator costing less than $200.
RPN-25 CE simulates the HP-25C version released in July 1976. Its major improvement in that update was "Continuous Memory".
While the simulator works just like the original calculator, a number of carefully designed extensions make it massively more powerful.
Features:
• Photo-realistic look
• Programmable (99 or 999 steps), subroutines, conditional loops, branching
• Insert and delete steps with automatic address correction
• 15 user-defined function keys of up to 6 characters each, redefinable under program control
• Programmable text messages
• Program Auto-Start option upon loading
• 100 symbolic labels
• 100 visible registers, "non-volatile", with unrestricted store/recall arithmetic
• 100 flags, visible at a glance
• Single-step constants
• Program comments
• Program library with more than 150 programs pre-installed
• More than 270 functions and operations not available on the HP-25
• 100 sounds built-in
• Much faster than the original
• "Live" register view supporting user interaction (run/stop, single-stepping)
• "Live" stack view
• Thousands separator (optional)
• High-contrast display (optional)
• Selectable pause length (up to a day)
• Program listing view with program title and description
• Program library view
• Store, name and retrieve any number of programs
• Sharing: Files, iCloud Drive, e-mail, AirDrop, Dropbox, copy, paste, print
• Import and run RPN-32 CE and GO-25 programs
• Run a large number of HP-41 programs with little or no changes
• Clock display (AM/PM or 24h)
• Supports Dark Mode
Calculator functions:
• Statistics, including clearing statistics registers only
• Factorial for arbitrary arguments
• Trigonometric functions (degrees, radians, grads)
• Polar/rectangular conversions
• Inverse, square root, logarithm, exponential, Pi
• Percentage
• Storage arithmetic (store and recall)
• Extended stack operations
• Low-battery warning
• Sound alerts
• ..and many, many more

Best app ever
Best app ever! Excellent and realistic HP 25 emulation. I had this calculator when I was a teenager, and it prompted my 20-year career in software engineering. Thank you so much for the trip down memory lane. And I actually prefer using this calculator app than iOS’s native calculator app! Thank you.
Outstanding app, great developer!!
I have been using the HP25 hardware calc since I purchased it in ‘76. It still works to this day. This app is exactly what I have been waiting for, even better than the real calculator. Thanks Willy for building this, your apps are the best!!!
