Great! I am very happy with this Andro11C calculator program/app installed on my Google Nexus 7 tablet. Installed 6 months ago and It works like my 30 year old HP11C calculator. Looks like the the HP 11C. Easy to use.

Gerald Meyer

Looks like the real calculator I used for over 20 years. If you like HP RPN Logic here it is. Love it

Gonzalo Balerdi

Awesome Ive been using it for a couple of years, but I never wrote a review. I love HP 15C my 3 real ones, and this one also. :)

Jakab Ferenc

Crash on startup As of version 2, the program crashes on startup with an "out of memory" error on my Xperia X10i (the last working version was 1.5). I'm hoping this will be fixed soon.

Robert Jahrling

Incredible My one complaint is that it is unrealistically fast compared to my actual 11C. Just kidding--this is an amazing emulator. I have had my 11C since 1988. I used it through high school and college and I still use it today. Until now. I find that the emulator, just by virtue of its speed, is actually better than the real thing. Seriously. The only thing I'm going to miss is the feel of the actual buttons. As far as I can tell, this emulator is perfect. Thank you SO MUCH.

Ed Poor

Math teacher loves it I tutor math from 2nd grade to junior high school, and this is far and away the easiest calculator to use! Doing PEMDAS calculations is easier to understand with RPN.

Peter Lawton

Almost... As good as the real thing. I use it all the time. If only it had the buttons.... ;)

Andrew Rodda

Perfect Regular tweaks. Closest to the real thing.

Mark Ratcliff

Mark Ratcliff Before the recent update, all was great. Since the latest update, I have had only trouble with the app loading and the display is blank. All buttons are locked at that point. I have to close the app and try to reload many times before it works. When it does load, it takes over 10 seconds to show on screen. I have a Samsung Galaxy S3. Please fix the bugs.

Joseph Slone

Joe My HP11C died years ago. I have never been able to find a suitable replacement. Until Today!

John Hinant

Works just like the real calculator I still have my 11C and this app accurately mimics it. The only thing missing is the information on the back of the calculator. Would be nice if that was included in the help menu.

Randy Mayer

Great app. Behaves just like the real thing.

Michael Farrell

Great!! I love my HP; now I have two.

Emilio Pirotti

Great having my food old 11C in my pocket again!! I just love this app, works great. Only flaw noticed: on my HTC Desire V ICS every now and then rotating the screen jams the view (weird zoom)

Bijan Nemati

A joy to use Flawless design and very reponsive.

Søren Pingel Dalsgaard

Very good and nice price Can't beat the price and features. A must-have! One wish: copy value in display when tapped for easy pasting to other apps

Bruce Naylor

A great emulation of the 11C I have used HP calculators since the 41C came out. Of all the apps available for HP and RPN calculators, this one is the best. Now if the author would just do the 15C...


Great but minor problem with the ON button Nice graphics and works very well. Looks so much like my real 11C that I have been using for about 20 years! Be aware however that if you press the ON button it will reverse the , and . display, so a number like 'two thousand point four' will appear like 2.000,4 rather than 2,000.4 which can cause confusion. Just press the ON button again to switch back again. I have offered feedback that the ON button may be better served as a screen dimmer function or a screen blanker (perhaps showing only an ON button?). Other than that, well done !

Works great! I have a 15C and the font is too small. I now use this more than the 15. Good app.

Albert Graef

Perfect I've tried quite a few of the other HP calculator emulations, but Pfutzenreuter's calcs (both the 11C and the 12C) are simply the best in the market. I'd give them 6 stars, though, if there was an option to save and reload the program memory, and a key click option for those devices without haptic feedback. ;-) Also, would you consider to do the 15C as well? Please!

Jerry Dallal

$4 when there are free options?! Well worth it!!! I've used a bunch of the freebies, but they never felt quite "right". It got to the point where I'd prefer an old 12c for scientific work, even though it meant a lot of f-PREFIX or multiplying and dividing by large powers of 10. This one feels just right. I have my my smartphone's AutoRotation turned off in portrait mode, so the ability to lock Andro11c in landscape mode is a real plus. What I'd like to have added: click response as an alternative to haptic response (both with on/off for those who like neither, of course)

Roy Payne

Perfect I've had my old 11C since 83 and this one allows me to always keep it close. Thanks!

A Google User

Great program, just like the real one! To commenter Frank, on a real 11C, hold the decimal point button when turning it on to toggle the decimal from comma to dot.

A Google User

Works just like the original Functions perfectly, very stable, excellent graphics.

A Google User

Geek Heaven Awesome. I have been using my 11C for 30 yrs. Would be nice to have period decimal option.

A Google User

Great app! Very nice on Nexus 7. I'd like to see the t on the enter key moved to the right a pixel or two ;-)

A Google User

In a pinch When I don't have my 11 with me, this fills the bill. Love it

A Google User

Beautiful! Probably the most asthetically-pleasing hp rpn emulator in the Android marketplace. I had a problem initially with the zoom level sticking, but the developer was responsive and resolved the issue. Highly recommended!

A Google User

Love It I love this calculator, and I use it everyday. It's the best of all the RPN scientifics, but please make a portrait layout. Its a pain to always turn my fone sideways to use it.

A Google User

Works like a charm As good as expected.

A Google User

Sharp and clear fonts on keys, perfect feel and feedback. Good start. Needs Load and Save of memory.

A Google User

Excellent implementation. Nearly prefect emulation of the real thing. Responsive developer.

A Google User

Wow. Finally found a calculator for the razr that is near perfect

Christopher Washburn

Useless Doesn't fit the screen for maxx and is unusable. How do I get a refund?

Ruben D. Garcia

Very good app Do you think to make the emulator for the HP 41CV, is the best HP Calculator

Louis Vezina

Best You are a student, an engineer or a scientist, look no further for a calculator, andro11c is the best RPN out there.

Gonzalo Balerdi

Yeah old icon is back! Well not exactly, but still better than the other one. Thanks!

Doug Evans

I used to like this app. Now too many useless changes. I really liked the orange 'f' icon... easy to find and tap. Now the icon is gray with a gray 11 in it. Major change and poor visibility. At least change the color back!!! Second: the "self test" when starting the app takes TOO LONG. Its really annoying waiting for this. I think I'm going to search for another HP calculator.

Dan Pribeagu

Amazing Very nice and useful application. New Icon, unfortunate; dull gray must go to bright orange!

Houston Brown

I wish I'd known... I never would have purchased a backup HP 11c. This app is more like the original than the original! Just awesome.

Alan Edwards

HP 11c Love the replication, but I think the revised icon is not representative of the calculator and looks like 11g, not 11c

Carlos von Muhlen

Handy! Like my old HP11c, performing.

Nick Kitson

Awesome Nothing more to say!

Clark Burton

Perfect clone of 11C

Todd Stewart

Hate New Icons The new icons are awful!

Martin Stabb

HP11C My one criticism is that it is just as slow as the original. This, I think, is too much authenticity. 2 Sept 2015 - Critisism rectified, now works at blistering speed. Slow speed option may well be useful for debugging.

Jen K

Best replacement for the one that got away, with the thief.

John Dunn

Mmmm But do all of its workings function ?

Rick P

Just love it. I've owned a 11c since they came out. Thus is as close as you can get. Awesome!

Les Wright

Excellent See my review for Andro15c. Excellent performance and value. Well worth the price to upgrade from the less powerful free version.

Mario Martinez

Fantastic app Great app I like it very much. Everything works fine, except the sound feedback,needs to be improved . Otherwise great app. I'm happy with it.

Jim V

Outstanding modern replacement As the original models are getting harder to find, this is the perfect replacement. The ability to program in the original code format is excellent. App is worth 10x the price
