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

Additional Information
Version history
5.1
Oct 19, 2024
• The instruction "ERROR nn" with nn = 99 will cause the display to blink rapidly three times.
Bug Fix:
• In the sample program "41-Curve Fitting (Kolb)", the equation for curve 3 ("Combined Linear and Hyperbolic") was incorrectly shown as y = a + b/x + c/x instead of y = a + b•x + c/x. Tap "Restore Sample Progs" in the program list to see the change.
5.0
Jul 02, 2024
• New sample program "Holidays multilingual" shows the date of Ash Wednesday, Easter, Ascension, Whitsun, and Corpus Christi for any year in the range 1583 to 4099 in three languages (English, Spanish, German).
• New sample program "41-Curve Fitting (Kolb)" automatically finds the best fitting curve (out of 20) for a given set of data points.
• Toggle LED vs. High-Contrast display: f double-tap display
• Toggle thousand separators on/off: f triple-tap display
• Setting flag 41 causes ∑+ and ∑- to use the HP-41 locations of statistical registers.
• Added warning when attempting to alter a Sample Program.
• The trig mode indicator DEG is switched off after the selected "Pause Length".
• "FC?S nn" (renamed to "FC?S/C nn") acts as "FC?C nn" if flag 41 is set.
Changed instruction:
• "∑SWAP41 nn" (was ∑SWAP41)
Swaps the current RPN-25 statistics data block with the HP-41-compatible block at the location Rnn.
Bug Fixes:
• Calling up the Rydberg constant in the sample program CODATA 2018• would cause a crash.
• Alignment of messages (MSG,MSGP,MSGP) could be incorrect in some cases.
