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! 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.

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!!!
