Just Brilliant A superb emulation of the most useful RPN calculator of HP in its heyday. I find it incredible that I can carry this around in my phone and I can leave my HP 48GX at home. Thanks ever so much.

[2013-08-11] A Google User:
Great emulation!!

[2013-08-02] A Google User:
Very good 42 emulator This is a very nice and capable implementation of the HP 42s which many HP calculator fans consider to be the best RPN programmable (pre-RPL) calculator HP ever made. The emulation is even better than the real thing in that it can save and load programs from files. And it's free software! Get the alternative Android skins from the developer's website, they look really good. Items for the wishlist: On my Nexus 4 the LOCAT function doesn't appear to work, and I find that the printer output is a bit small. But apparently these items are already on the TODO list, so I give it 5 stars nonetheless.

Just perfect :-)

[2013-07-24] A Google User:
Great If you like HP calculators this is for you.

[2013-07-17] A Google User:
Great App! This is a great emulation of one of the best scientific calculators ever made. I have used it in my engineering career on the PC for many years. It is great to have it on tablets as well.

[2013-07-10] A Google User:
Just about perfect Exactly the same as the desktop app, except that now it's hand held. It's like having the original hardware. Shame it doesn't work with x86 installations of Android.

[2013-07-09] A Google User:
Badyal Hp42s calculator very popular and power full for engineering,finance surveying other mathematics work l like it I used befoe different way. I am fully setsfiede from thih product Thanks

[2013-06-27] A Google User:
Can not fault this simulator, HP should never have discontinued the beloved 42s. This app is a savour to old school engineers

[2013-05-30] A Google User:
Great App!! Works perfectly, no hang-ups. Becoming my favorite over the 11 & 15 C series. Got to get a manual now.

[2013-05-16] A Google User:

[2013-05-09] A Google User:
Excellent! Just like my old one.

[2013-04-30] A Google User:
Simply perfect

[2013-04-25] A Google User:
William This is just great and wonderful, is just what I need for calculation

[2013-04-19] A Google User:
A most excellent app. The HP 41 compatible nature A most excellent app. The HP 41 compatible nature is excellent for many engineering tasks. The new display scaling/smoothing is nice for small displays. I've tried Droid48, and it's too buttony, and not licensed for work use. I'm enjoying the occasional program. Get QPI and FCTR (nice). Eventually you might need a manual, but if you know RPN then you'll get far.

[2013-03-25] A Google User:
Simply the best! Once I had a real one, but know I have a real one. It was and still is the best calculator ever. Great job. Thanks.

[2013-03-18] A Google User:
My favorite calculator! The graphics looks a little flat but other than that, this is simply brilliant... Can't thank you enough :-)

[2013-02-15] A Google User:
Best calculator ever On both android and as a physical calculator. Yay! and thank you.

[2013-02-09] A Google User:
Fluids Engineer I still have two 42 s HP calculators.I am very surprized to see a download for the calculator; bur very happy as well. By far tbe best calcator ever.

[2013-02-08] A Google User:
Smasung Galaxy Note The QUIT - <YES/NO> window is irresponsive.

[2013-02-03] A Google User:
Unreliable answers Can easily get it into a state where the calculations are wrong. For instance 9 / 2 = 4.0. This means one cannot rely on it for daily use. Please fix. Then I'll use it every day....

[2013-01-09] A Google User:
Thank you! My heart was broken 10 years ago when my beloved 42S got stolen. Now, thanks to Free42 not only I have one, but three of these fabulous calculators (in my PC, phone and tablet). If this app would cost $50 bucks, I'd still gladly pay for it.

[2013-01-07] A Google User:
Thanks.

[2013-01-06] A Google User:
Perfect All you RPN nerds need this calculator.

[2013-01-06] A Google User:
Its an HpCalc app It does exactly what one expects it to and does it well. If you need a REAL (aka RPN) calculator app for your phone or tablet this a great on.

[2013-01-06] A Google User:
Perfect Great app. Perfect replacement for my 42s which is on it's last legs.

[2013-01-06] A Google User:
An old friend First thing I install on any computing device I own. Good replacement for my 42s whose top row keys don't work

[2012-12-30] A Google User:
An old friend comes to Android The HP42-S is without a doubt one of the best calculators ever. It is especially good for engineering students. The way it handles complex numbers, as single entries on the stack, I found a specially useful. As I no longer have my original, this app is very welcome addition to the Android lineup.

[2012-12-15] A Google User:
The best The best RPN calculator ever, and the best simulator for it.

[2012-12-03] A Google User:
Great app for the best HP calc Loved my 42s loaded with survey solutions by Software by D'Zign. Will key in a few routines, now that my original 42 died in the field.

[2012-12-03] A Google User:
Great app! Nice job... I only have this app four stars because now I have no need for my prized physical version.

[2012-11-29] A Google User:
Perfect HP Calculator This app is a great re-implementation of the perfect HP calculator--the 42S! My only wish: that I had found this app sooner.

[2012-11-27] A Google User:
Thanks Very Much 20yrs on & still not much beats the 42s. Always travelled with my 42s very close to skin for fear of loosing it. Now after all those years of brilliant service it can enjoy a safe retirement with all other prized possessions & your brilliant App means the 42 will always be as close as a phone & the key vibrate update means it feels like the ledgendry original. Amazing job, rates more than 5 stars. Thanks again.

[2012-11-27] A Google User:
Nikkel Survey Fantastic app that allows the HP42s to live on.

[2012-11-26] A Google User:
Great Work

[2012-11-25] A Google User:
Fantastic HP emulator I've never owned a 42, but I love this app. I've owned a 15C and a 35, and this is a fine way to scratch the HP itch in a free android app.

[2012-11-25] A Google User:
Its a 42 ^above^

[2012-11-25] A Google User:
HP42s Just like the real thing, only with much more memory.

[2012-11-25] A Google User:
Great work!

[2012-11-25] A Google User:
My favorite RPN calculator I've been relying on Free42 since its Windows Mobile days. I now use it on iOS, Win7, and Android. I don't like any of the default skins, so I authored my own. Look for Andy_600x700 in the optional skins pack if you want a clean, legible skin.

[2012-11-25] A Google User:
Excellent The best 42 emulator. Nicely done.

[2012-11-25] A Google User:

[2012-11-24] A Google User:
Great Fantastic, still got my HP 42S and use it weekly but don't carry around with me all the time. Will never replace my old HP 42S and will still continue to use it, but now I got one on my android devices always with me.

[2012-11-24] A Google User:
Cool I own the real one but this program is a perfect copy. Now I have the HP 42s always with me! Well done,

[2012-11-20] A Google User:
Big fan Used a 42 all through college and was very happy to find this. Works well, looks good, and I enjoy using it.

[2012-11-13] A Google User:
Best RPN app for Android What more can you ask for. Probably the all time best calculator by HP on your phone for free. Does matrices, complex numbers and numerical integration with ease. I have this app on my home screen all the time for all my calculator needs.

[2012-11-05] A Google User:
physical owners : please contribute manual ! can those with an original manual please fill in missing parts in the free42 manual! see emulator wiki and the brazilian guy who started the ersatz manual. there are some bits missing !

[2012-10-06] A Google User:
I Think I'm Going to Cry! I still have my original HP 42S and the manual. I routinely replace its batteries and occasionally use it. This calculator got me through engineering and to see it so faithfully and lovingly recreated on my phone, well it brought back a flood of memories and I'm even now practically wallowing in a sea of nostalgia. This IS awesome. My only suggestion, and it's really only that, not a request, would be to make it a screen lock app. I'm not sure if there is an app to do this or if it can only be coded into an app. Bravo and thanks, Marc

[2012-09-16] A Google User:
Exactly what it should do I had a 42S for twenty years before tragically losing it, and nothing HP makes today can touch it. This app obviates any desire to worry about an HP (or other calculator app) replacement.

[2012-09-07] A Google User:
HP 42S emulator This is the best emulator of the one of the best scientific calculators ever made. I have been using this application for about six years on the desktop, laptop, palm pilot, and now DROIDX.

[2012-08-26] A Google User:
Needs haptic keys! Excellent, have this installed on every device I use. LCD contrast on original calc is dreadful, only reason I still use it is because of the physical keys. Haptic feedback on this app would make me consign the well worn thing to the box where I keep my old 41c and my Dads 70's HP calcs.

[2012-08-21] A Google User:
Captivate Excellent !!!

[2012-08-17] A Google User:
Amazing Amazing emulation of HP 42s! RPN calculator in my new smartphone, so convenient! Thanks for creating this app!

[2012-07-31] A Google User:

[2012-07-29] A Google User:
Simply awesome! Thanks!

[2012-07-29] A Google User:
Great app! I've used this calculator for 30 years through school and as an engineer. Now spl I use is this app and it works great!

[2012-07-28] A Google User:
Excellent Get it!

[2012-07-28] A Google User:
Excellent! By far the most used app on my phone. Works just like the HP-42s sitting right next to me, which I no longer have to carry back and forth to the office.

[2012-07-25] A Google User:
Awesome Almost as good as the real thing. Works perfectly. Thanks!

[2012-06-26] A Google User:
HP TAKE NOTES Loyal fans of this calculator continually download this app. It works. Programming is a breeze, and you're not limited to a lettering system like the hp33. Whats the problem? Kudos on this app!

[2012-06-19] A Google User:
Works great The layout, the sixe of the buttons, everyhing feels right and i lovw rpn. This and realcalc are the best

[2012-06-12] A Google User:
Neat :)

[2012-05-29] A Google User:
My hp Almost as good as my old 15c

[2012-05-24] A Google User:
Best Calculator This is the best calculator on the market. You'll need to learn RPN but once you master it, you'll never go back. There's an HP48 emulator too, but this one fits and looks much better on a smart phone screen.

[2012-05-15] A Google User:
Great! Very nice re-creation of my fav HP calculator. And it's free (as in beer) and open source. (tho I do wish the graphics scaled better for the large Galaxy Tab 10.1 screen.)

[2012-05-14] A Google User:
outstanding I have had and used many HP calculators since 1972, probably have 5 or 6 in the house right now, and the 42 is still my favorite in terms of keyboard layout, functions, and especially the transparent complex number capability. In "the flesh" this model was very limited by its lack of I/O like elder brother HP-41. As an emulator that no longer applies, so its ease of use brings it to the top of the stack. Developer is obviously actively supporting this one since I get an update notification every week or two. Congratulations Thomas Okken and thanks for your contribution.

[2012-05-11] A Google User:
Stephan Just Awesome!! Like the real one period And I still own one, but this is a very good substitute.

[2012-05-11] A Google User:

[2012-05-09] A Google User:
Very good Thx

[2012-05-06] A Google User:
Can't live without it It's exactly like a real-life HP-42S, perfect in every way.

[2012-05-05] A Google User:
Just like my beloved hp 42s I have 2 suggestions add send feature to printout so i can send jpg image to Bluetooth printer or mms and haptive feedback. Thanks wonderfully app!

[2012-04-19] A Google User:
Thanks. Works wonderfully on my Galaxy Note.

[2012-04-16] A Google User:
Awesome Can't thank you enough.

[2012-04-16] A Google User:
Latest version is excellent The update fixes the one minor issue I had with the software which was the quality of the number display on my Galaxy Nexus. I'd give it six stars if I could...

[2012-04-15] A Google User:
Puts the "smart" into my phone All the functionality of my long-gone HP42.

[2012-04-14] A Google User:
Every bit as good as the original All my old HP 42s programs work perfectly.

[2012-04-10] A Google User:
Handy Excellent emulator of my trusty 42.

[2012-04-10] A Google User:
Works just like my beloved 41c did I have missed my old 41c that saw me through engineering school, but now I have it back in all its "Enter > Equals" glory!!!!

[2012-04-09] A Google User:
Very impressed I have tried most of the HP calculators in the market and this I think is the nicest to use very impressive

[2012-04-05] A Google User:
Wonderful! It's brought me to tears at just how beautifly its captured the HP 42S! I love it too!

[2012-04-01] A Google User:
Fantastic, thank you. Installed to my HTC Sensational XL and works perfect. Been using HP reverse entry method since student time. This application is fantastic ! Next will try to install program .......

[2012-03-06] A Google User:
Thanks so much A great app

[2012-03-05] A Google User:
Eng Love that it fits the larger screen - prayers answered for a die-hard HP user, as I now have RPN available anytime, anywhere.

[2012-02-29] A Google User:
Great app Works like the real one

[2012-02-13] A Google User:
Thank you! I discovered this just a few days ago and am thrilled. Have used the 32SII and 42S for years in my engineering career and this is an outstanding emulation. Thanks for making it for big screens now!

[2012-02-13] A Google User:
Awesome Now I can use all of my old programs, portable!

[2012-02-12] A Google User:
Great Excellent app. Does everything.

[2012-02-12] A Google User:
Free42 Great, great, best calculator ever! Thank you so much for the update! Looks great on my EVO 3D now!

[2012-02-09] A Google User:
Alive again! Awesome! I love high-tech, but I also like my old 42s. If you could put my custom surveying programs into this, I would pay real $$ for it! Bigger buttons would be great.

[2012-01-30] A Google User:
The best of HP's RPN series Just like my original HP42s but only better. Also installed on my PC's.

[2012-01-11] A Google User:
Free 42

[2012-01-10] A Google User:
Maybe the best UPN calculator. Absolutely free, open source, no adds. The developer attends to the program and fixes all problems. Try the website for links to ready made scripts. Somebody even made a manual available in case you don't know this calculator model.

[2011-12-16] A Google User:
A great emulator for a great calculator! A great emulator for a great calculator! However, the skins only expand to something like 640 x 910 pixels, which turns out tiny on my 800 x 1280 phone.

[2011-11-24] A Google User:
Just like my real one, just like the PC application!

[2011-11-10] A Google User:
Just like I remember it. I started with a slide rule in the early 70s and moved on to HP calculators as soon as I could. I think RPN is very intuitive. This is a great app!

[2011-11-07] A Google User:
Great calculator Just like the original, fantastic

[2011-10-06] A Google User:
Very nice I like it!

[2011-09-26] A Google User:
Great emulator. Even better with custom skins.
