RPN vs Apini

RPN-32 CE is the first photo-realistic simulation of Hewlett-Packard's popular mid-range scientific calculator HP-32E for the iPhone. Produced from 1978 through 1983, it was the "Thyme" member of the third-generation HP calculators known as the "Spice" series. While the simulator works like the original calculator, a number of carefully designed extensions make it a lot easier to use. Unlike the HP-32E, this version is fully programmable, running virtually all programs written for the HP-25! Features: • Photo-realistic look-and-feel • Programmable (99 steps), subroutines, flags, loop control, branching • Insert and delete steps with automatic address correction • 20 registers, "continuous", with unrestricted store/recall arithmetic • Indirect register addressing • "Live" register view • Program listing view • Program library view • Store and retrieve any number of programs • Sharing: e-mail, AirDrop, Dropbox, copy, paste, print • 44 programs pre-installed • Import GO-25 programs • Export programs to RPN-25 CE Calculator functions: • Statistics (mean, standard deviation, linear regression, normal distribution) • Factorial • Trigonometric functions (degrees, radians, grads) • Polar/rectangular conversions • Hyperbolics • Inverse, square root, logarithm, exponential, pi • Storage arithmetic (store and recall) • Percent change • Percentage of Total • Unit and hours conversions • Many additional functions not found on the HP-32 Details: cuveesoft.ch/rpn32

Apini ends on 30 September 2026 Apini is being discontinued. 30 September 2026 is the last day the app and its cloud services can be used. After that the servers are switched off. The app stops working, and anything still in Apini can no longer be retrieved. If you use Apini, please export what you want to keep before then. Open your Honeycomb, open the three-dots menu and choose “Export Excel”, or open apini.cloud in a browser and copy your items over to other systems. If you have a lot of Honeycombs, write to info@apinilabs.com and we’ll prepare a bulk export for you while the system is still running. The free and open building blocks Apini was built on stay free and open. We’re working on giving them a lasting home, independent of any single company - more on that soon. Today you can find them at labfreed.org.
