### 1/5 — Programming not currently working

*2023-07-08*

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!

### 5/5 — Brillant Emulator

*2026-01-31*

This was my first programmable calculator at age 14. The possibilities and programming examples really changed my life. This app is a remarkable good reproduction of this great piece of hardware. Thanks for making it so realistic and versatile!

### 5/5 — Fantastic app

*2024-11-27*

I missed my Hp-25 calculator so much these past 40 years. It was my beloved tool when I was an Engineering student at Laval University in Quebec. This app makes it possible to experience this great calculator again! It works exactly like the one I had, in Vintage mode. What great memories. Many thanks to the developer!

### 5/5 — Best app ever

*2022-04-15*

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.

### 5/5 — Outstanding app, great developer!!

*2020-09-04*

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!!!
