[2013-09-30] A Google User: Finally! Finally an RPN calculator that is functional and looks good. |
|
[2013-09-28] A Google User: Very good RPN calculator. Highly recommend this calculator for anyone. |
|
[2013-09-25] A Google User: Love this calculator My beloved 15C hasn't been out of its protective cover since I got this app. I haven't tried any other RPC calculator apps, but I have no need or desire too. This does everything I want. One feature I'd love to see: a widget that I can place on my lock screen for quick access to the calculator. |
|
[2013-09-21] A Google User: Nice This is exactly what I was looking for. If I could ask for one thing it would be that the fonts were slightly larger. I almost need my reading glasses to use it. (yeah I'm and old fart, that's why I use RPN). Update (9-21-13) The fonts have been enlarged on the latest release - Thanks so much for listening to our feedback, I don't need my reading glasses to use it! Also, I love the basic mode, most of what I do at work (electronic design engineer) can be done with this mode. Bravo to a great app. |
|
[2013-09-17] A Google User: Nice. This is great, but there's a bug. The C button clears the stack. It's not supposed to do that, that's what AC is for. (My bad! Thank you for the reply, haven't quite figured it out right away.) |
|
[2013-09-17] A Google User: Самый удобный калькулятор. Жаль, что этот калькулятор не программируемый. Поставил на телефон несколько RPN-калькуляторов, но этим пользуюсь чаще всех. Потому что он самый удобный: кроме "Scientific" есть режим "Basic" с большими кнопками. |
|
[2013-09-16] A Google User: Almost don't miss my HP |
|
[2013-09-16] A Google User: Excellent app! As someone who went to college using hp rpn calculators, this app is not only excellent but brings back good memories of the days when rpn ruled the world... |
|
[2013-09-14] A Google User: The % operation works even better than on the original HP calculators. than on the original HP calculators. |
|
[2013-09-13] A Google User: Fantastic! The best features of the HP-25C, the HP-11, and the HP-16 all combined in one app. HP calculator lovers (like me) will love having the features, feel, and appearance of these classic HP devices. There's even a Basic mode, which provides basic 4-function features with RPN. Those who try it who haven't discovered the advantages of RPN will be thankful they did. I can't thank the author enough! |
|
[2013-09-11] A Google User: Best in class Nicely done. No issues at all. |
|
[2013-09-10] A Google User: Fantastic!!! An excellent tool for those who never buy more than one lottery ticket. |
|
[2013-09-10] A Google User: Awesome I use it multiple times per day. I have never had a problem |
|
[2013-09-10] A Google User: Absolutely impeccable! Designer clearly took great effort to replicate the look & feel of a trusty 15c. Magnificent example of quality programming. |
|
[2013-09-10] A Google User: Great RPN calculator RPN may seem awkward at first, but it works more like our minds, it's faster and more accurate than conventional calculators. |
|
[2013-09-10] A Google User: Fantastic implementation Having grown up with RPN during university (HP 41) it was a pleasure to find a full fledged RPN emulator for my devices. Fantastic look and feel. I use it daily. Well done! |
|
[2013-09-09] A Google User: Yay Rpn for android! Nuff said |
|
[2013-09-09] A Google User: RPN just like my old 11c! Thanks so much for doing this, and for doing a great job with it. |
|
[2013-09-04] A Google User: Great Looks more like an HP in landscape mode. |
|
[2013-09-04] A Google User: Great app foot an rpn calc Works well |

|

|
[2013-08-22] A Google User: The best! Excellent version of the old HP RPN calculators - and it's free! |
|
[2013-08-22] A Google User: Excellent This is an excellent calculator app and by far the best that I have tried and I have tried many. This one will stay with me. It's a perfect replacement for my HP RPN calculator and I highly recommend it. Change to the world of RPN and you'll never look back. |
|
[2013-08-14] A Google User: Awesome!! My favorite, most used app, ever. |
|
[2013-06-07] A Google User: Very well done Excellent rendition of the classic HP RPN calculators. Just like trusty old HP 11, only better. I like the addition of BIN/DEC/HEX/OCT modes. Kudos to the developer. Great job! |
|
[2013-05-29] A Google User: Great Calculator Great for people used to an HP48/49 or similar. The help is good too for those few things that are different. |
|
[2013-05-23] A Google User: Awesome The best of the very few calculators that will automatically calculate Pythagorean Theorem allowing conversion of coordinates to angles with distance measurements. I use for survey work in the field and it works great. |
|
[2013-05-19] A Google User: Great calculator This calculator is great. Great replacement for my old HP15c. Always installed on your my android devices. |
|
[2013-05-15] A Google User: Look no further, this is the one This is a very nice calculator. It is easy to hold and use in one hand while you hold your pencil in the other. I recommend that you set the stack depth to four and turn on key clicks ( vibration). |
|
[2013-05-11] A Google User: Love it... This is my favorite of all the apps I have installed. Long live RPN! |
|
[2013-05-10] A Google User: Just like an hp 10c! |
|
[2013-04-29] A Google User: Nice! Very good RPN scientific calculator for your phone or tablet. This is quickly becoming my first choice over droid48 and free42 because of the nice appearance and usability on the tablet. Thanks! |
|
[2013-04-14] A Google User: Love the new look Just need to add it to the pay version too. |
|
[2013-03-19] A Google User: Excellent At first I wanted an HP 15C calculator but then I found this. And it's great. I forgot that all I really wanted was a good RPN calculator. The guy doesn't seem to market him or her self very well - no way to rate app from app, for example - so could do better for themselves. Recommended. |
|
[2013-03-10] A Google User: Rpn Calc Great rpn calculator well layed out, very stable. Highly recommended. |
|
[2013-02-28] A Google User: Perfect Better than my hp35(s) |
|
[2013-02-23] A Google User: Rpncalc Excellent Thanks! |
|
[2013-02-20] A Google User: Works great on Samsung Gslaxy S3 Outstanding! This simulates the look & feel of my trusty HP 11C. Love returning to RPN! (Samsung Galaxy S3) |
|
[2013-01-29] A Google User: RPNCALC Excellent |
|
[2013-01-04] A Google User: Perfect! Price is right, looks great, functions as you'd expect. |
|
[2012-12-22] A Google User: The best RPN calc for Android. This app is awesome! Just what I was looking for. |
|
[2012-12-02] A Google User: Absolutely the best RPN calculator! Simply put, it work, without any drama, without any hiccups. I'd pay for it if it wasn't free! |
|
[2012-11-20] A Google User: - Very good app. And would be even better with the ability to deal with fractions using the decimal twice, like a 32sII. |
|
[2012-11-13] A Google User: Perfect Thanks--greatly appreciated! |
|
[2012-10-05] A Google User: Joe The new light faceplate is not a good idea. Makes the calculator look extremely cheap and is bad on the eyes. Need to be able to download the original version. |
|
[2012-10-01] A Google User: Decimal Places Great application. How do you increase the decimal places? F + 4 does not seem to work. Thanks all. |
|
[2012-09-07] A Google User: Great Great work |
|
[2012-09-05] A Google User: DRL Nice, however C should clear x and not the stack. |
|
[2012-09-03] A Google User: Awesome! A proper calculator for android... |
|
[2012-08-15] A Google User: Works as well, if not better than, my HP. Sometimes I'll even grab my phone instead of the calculator when they're sitting right next to each other on my desk. |
|
[2012-08-11] A Google User: Omg!!!!!!! Enter>= lol |
|
[2012-08-02] A Google User: Best RPN for Android As a long-time devotee of HP calculators when they were still great (41CX and earlier), I say this is the absolute best I've found for general use Android. If you need financials, the 11c emulator will be better for you. For the rest of us, this is the real deal. |
|
[2012-07-25] A Google User: Orig interface back! Now that original GUI is back, this is pure outstanding! Very close to my old 11C, works great. Surely best free app ever. Thanks! |
|
[2012-07-21] A Google User: The best rpn calculator Now that the old look is back, this is the nicest looking calculator in the market. |
|
[2012-07-17] A Google User: Excellent! This the best app I've ever downloaded. |
|
[2012-06-26] A Google User: Nice |
|
[2012-06-22] A Google User: Great Great tool. I had been looking for an RPN calculator for my phone and this one is fantastic. |
|
[2012-05-30] A Google User: A very good app It operates very closely to my old HP15 c |
|
[2012-05-30] A Google User: Very Good I'd like to see a radix (decimal point) on BIN, OCTAL, HEX numbers. Example 0.0B hex = 11/64. Thanks! |
|
[2012-05-26] A Google User: Love it! |
|
[2012-05-25] A Google User: Awesome Best RPN for free. What more can you ask for. |
|
[2012-05-21] A Google User: RPN all I have to say Nice interface. I needed RPN on my phone. |
|
[2012-05-18] A Google User: Excellent free RPN calculator It's not an HP-15C, but that's ok - it does plenty, and I've found myself using it more than almost any other app on my phone besides email, camera, facebook, and texting. |
|
[2012-05-16] A Google User: Just Like My Old 15C I still have my 15C but this one accompanies where ever I am going. |
|
[2012-05-16] A Google User: I like new look |
|
[2012-05-16] A Google User: Classic look and usable Due to stack display this one has a better |
|
[2012-05-15] A Google User: Best rpn calc I use it since my first Android phone. Best RPN ever and still free. |
|
[2012-05-13] A Google User: Glad the Old Skin is an Option Great app. If you love your H/P, you'll love this app. |
|
[2012-05-13] A Google User: Perfect! Escape from the pointless ”equals” key! |
|
[2012-05-13] A Google User: Love it It even looks like my HP. I use it all the time. There are a few quirks but it's not a big deal. I can't believe people uninstalling this because of the new look. It's still awesome. |
|
[2012-05-12] A Google User: Skin Previous skin better. More like HP calc. |
|
[2012-05-09] A Google User: Great calculator If you're looking for a functional RPN calculator, this is for you. It's not 100% consistent with HP, but good enough for this old fashioned engineer. |
|
[2012-05-08] A Google User: Great Great app as I prefer rpn to algebraic and with the latest update the polar to rectangular is awesome. Thanks for a great app! |
|
[2012-05-08] A Google User: RPN Calculator The desk icon was very nice, but the developer suddenly updated such with a lousy design! I uninstalled the application immediately and downloaded another RPN calculator from other developer. It is the Cineses saying "Ah Mau Bakery"! Find out the underlying meaning of it from a Hong Kong Chinese! |
|
[2012-05-08] A Google User: Ugly new interface The new interface is too ugly. I'm uninstalling it now. |
|
[2012-05-08] A Google User: Great calculator I've used this guy for more than a year. I love it, and its free. |
|
[2012-05-08] A Google User: Option to use original look? Love the app - but preferred the old look - can you provide a menu option for classic mode to give us back the old interface? |
|
[2012-05-07] A Google User: Beautiful Just like having your HP in your pocket all the time, complete with programming functions - only better. Love this app, thank you!!! |
|
[2012-05-06] A Google User: God rpn calc This rpn calc reminds me of my own hp15c calc which can almost everything I will go with this calculator for awhile |
|
[2012-04-13] A Google User: Not bad... Only one function-set missing stack-rolling and display. It is my favorite part on my HP38G. |
|
[2012-04-04] A Google User: Fantastic, great I worry that someday my HP15C will quit working. With this app, I know I have a back up. It works great and it landscape mode I can work the keys with my thumbs just like on the real thing. |
|
[2012-04-04] A Google User: Perfect Just what I needed |
|
[2012-03-31] A Google User: RPN - So much simpler. Just like the real thing. |
|
[2012-03-22] A Google User: Works great! Really nice. Interface is beautiful. Works great. A winner. (Samsung Galaxy SII) |
|
[2012-03-15] A Google User: Great! |
|
[2012-03-06] A Google User: TMAF Really nice interface,RON for life. |
|
[2012-02-29] A Google User: Yowzah!! |
|
[2012-02-16] A Google User: The best... Love it! No bugs! Rpn is awesome! |
|
[2012-01-27] A Google User: Rpn forever Reminds me of my old beloved 15c. Really like the basic feature. |
|
[2012-01-27] Eric: Rpn forever Reminds me of my old beloved 15c. Really like the basic feature. |
