Originally bought my 25c in 1978. Over the years it's disappeared. So nice to have it back. Thank you for such a great app.

I owned i.e. pc trace corrosion killed it N this exact replacement thank you

N70%

I loved my HP25 and my 25C. The most important aspect for me is the way its RPN logic works that added to the fact that i got used to handle it with one hand. I can now do that with my XPERIA ST15a. Great job.

There were many programs in books and magazines for the HP-25 that were very useful for real engineering problems.

This is a great emulator. Thanks Olivier

Thanks so much.

The keyboard need unreasonable precise touching in order to work.

X70%
by X####:

Works best with leisurely key entry, just like unbuffered 1970s analog keyswitches. Easy to read snd works great on Samsung Note phone.

Good for nostalgia , but the sticky keys get to be a pain after none too long.

C70%
by C####:

Does not respond to key touches on Droid mini xt1030. Also, option bar (...) at bottom covers the 1, 2, 3 keys. I also have my hp25 at home-- my first HP and it still works!

C70%
by C####:

Press a key and the phone vibrates but the digit often doesn't show on the display. Not really working is it?

I70%
by I####:

Brilliant! I loved my HP-25c back in my engineering school days and now I have it again. Works like a charm on my GS4.

C70%
by C####:

Yes, yes, it's pretty good. I got my first HP calculator nearly 40 years ago. And the go25c looks and acts nice once you can be sure you've pressed a key. But it takes a long press on each key to ensure a valid key press has registered, which makes using it just tedious, unlike Due Smit's 41c. A click after a tap would be nice.

Y70%
by Y####:

Keyboard unreliable. Vibrates but doesn't pick up all keystrokes. Too unreliable to use

E70%
by E####:

I miss my HP25 I used all through college, and for a few years after. I lost it many years ago and can't bring myself to replace it just for nostalgic reasons. This is the next best thing. Looks good, works very well. I agree with some of the other reviewers that the keyboard could use a little improvement. Some inputs are missed and there is no haptic feedback or click. Otherwise I would rate it 5 stars.

X70%
by X####:

Checked against the original 25C owner's manual and every function works perfectly. The keyboard issue is of easy solution: just remember that it is a 70's product, when the fingers were not so anxious and touch the keys with 70's speed.

I70%
by I####:

I have an HP 25 and this works just like it. Minus .01 stars for not showing a program switch

L70%
by L####:

Made me feel young again; The HP25 (without the "C") was my first HP calculator many many years ago. Tnx Olivier!

Y70%
by Y####:

Not quite the HP29C I used to have, but the retro vibe is great. I'm using this on my phone since the HP25 is clean, simple scientific calculator with red (simulated) LEDs! (To be honest, I do prefer my HP15C when I can reach it.) Thanks for a great program!
