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.

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!

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!!!
