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

• Trigonometric mode indicators: DEG, RAD, and GRD indicators are never shown in vintage mode. In normal mode, the default setting DEG appears only on the high-contrast display.
• Obsolete mode changes involving "magic numbers" 19390104 and 19390105 have been removed.
