RPN-25 CE 4.8.1

RPN-25 CE is a photo-realistic simulation of Hewlett-Packard's highly popular scientific calculator HP-25 for the iPhone. This application replicates the "Squash" member of the second-generation HP calculators known as the "Woodstock" series, in production from August 1975 to 1978.

A standout feature of the HP-25 was being the first programmable calculator available for less than $200. RPN-25 CE simulates the HP-25C model, introduced in July 1976, which notably added "Continuous Memory" to its capabilities.

While functioning similarly to the original calculator, RPN-25 CE enhances the experience with a array of carefully designed extensions that significantly boost its capabilities.

• Photo-realistic appearance
• Programmable with up to 999 steps, including subroutines, conditional loops, and branching
• User-defined function keys and programmable text messages
• Program Auto-Start option and symbolic labels
• Numerous visible registers and flags
• Program library with over 150 pre-installed programs
• Additional functions and operations compared to the original HP-25

Moreover, RPN-25 CE offers live register and stack views, supports a variety of sharing options such as iCloud Drive and Dropbox, and allows for importing and running programs from other calculators like RPN-32 CE and GO-25. With clock display options, Dark Mode support, and a vast array of mathematical functions including statistics, trigonometry, conversions, and storage arithmetic, this application provides a comprehensive scientific calculator experience.
