    i41CX is the same powerful advanced programmable RPN scientific calculator as the highly rated i41CX+ but without the latter s expansion and printer capabilities. It is functionally equivalent to the world-renowned HP-41CX and inherits ...
    This app no longer works It needs to be updated Too bad because this was my favorite calculator     No longer works Gunnerbeast
    It does seem functional but I hate the way it wastes screen space to try to look like the physical version of the calculator including ridiculously the case and ports on the top So the keys are small Key feedback is subtle and is not good I have Calc41cx and like it a lot better but it hasn t been updated for iOS 11 and is no longer in the App Store There s another free alternative my41cx ios but it has its problems The interface doesn t waste space with skeuomorphism but the interface is low contrast and it has literally no key feedback What to do             Functional but terrible skeuomorphic design GAPas
    Great calculator that is now perfect with haptic feedback Been waiting on this for years Now much easier to ensure you hit the right keys                     Yeah Haptic feedback Jeffcincy
    I bought an HP 41 for the first time in 1981 Still have it It was the best calculator money could buy and it was expensive This app works EXACTLY like my physical HP 41 The attention to detail is incredible I was thrilled when I found this app and gladly paid for it                     Fantastic jerrylanejohns
    Having lost my HP 22 19C 45 calculators this app is a perfect app and love it RPN habits are engraved in my brain and love this app                     Nice app for die hard HP calculator people XOXOHPXOXO
    With real programmability like the original now nearly 40 years old you should have little difficulty transitioning to the iPhone version Fish out the original manual if you re rusty it isn t supplied and yes you can upgrade in app for the emulated plug in packs nothing to download as they are already built in awaiting payment                     Magnificent Emulation Aardvark1917
    Love this app and my phone goes where I go And not lose any of my functions that I use often                     Retired civil engineer XOXOHPXOXO
    Very nice                     Replaced my HP 41C rogerms42
    When I m not at the office where my 41cv is I can have my preferred calculator with me as an app Nice J O B I purchased my 41cv in 1979 and still use it                     Reality nice app Mrp11
    I regularly use a HP calculator for engineering calculations and once I got used to Reverse Polish I ve found RPN simplifies complex string calculations This app provides a pretty much flawless emulation of the great HP 41CX It s great for quick calculations rectangular polar conversions etc AND I don t have to carry around a separate device it s on my phone If you don t need to graph functions and most of us rarely do AND like RPN this is a great app                     If you use a HP RPN calculator this is for you Doggydog8
    When I purchased an HP 41C in 1980 it was the most advanced calculator on the market Programmable and using RPN logic I enjoyed developing programs for science projects This version duplicates much of the original device and adds advanced capabilities Though replacing a couple of algebraic based calculators this i41Cx is my choice along with a graphing computer                     A Dream Come True Invisible Ed
    I grew up with an HP41 CV through 4 years of Physics classes This calculator is the closest match and does everything that I used to do                     Best calculator ever Marmoset Killer
    I have owned and used HP41CV since early 80 s and HP41CX since mid 90 s I still use them daily Had to scrounge everywhere to keep a working model going Although I would still prefer the feel of a physical machine this app is absolutely fantastic and I use it all the time It has performed flawlessly and is great fun since I now can have the calculator at my side to address or analyze the world around me It looks good it works good and it s a blast to have such access 3 2015 Update OMG After using this IOS version on my iPad Air 2 for awhile I am beginning to enjoy the IOS version more than my original HP I own 3 versions                     This is Great HP41CX v4 9 2 EcklarA
    This is a wonderful app that both looks and feels like the HP41CX I ended up getting some in app upgrades and may have chosen the more expensive i41CX had I known the app was this good It is especially useful to people who have used the HP41 series calculators Very helpful tech support                     Amazing Revrunning
    If you loved your hp41c and have been missing it here it is This is an exact replica of that greatness and it is perfect If you do not know 41C but curious about rpn this is it                     Welcome back 41C perfect Mehmet Ozturk
    Looks great fast programming is spot on and continuous improvement                     Why not 5 stars Teddytoons
    Works just like my old calculator except from my phone I wished they had changed the original digits because they were not easy to read to begin with                     Really an HP calculator arj2006
    This is a good trouble free app that emulates the classic HP 41C calculator very nicely I prefer it to the standard calculator app on the iPhone                     Nice HP 41C emulator Synecdoche60
    Not only was the HP41 the best calculator ever this app is the perfect reproduction of it The thing that really impresses me is that the app creator continually maintains it for new iOS releases fixes any rarely found bugs and adds features I ve used this app since I bought my iPhone 3G and have never had a problem Highly recommended                     Best Calculator Ever Bredtwest
    Great app If you like HP calculators you ll like this app Worth the price great job AL Software                     Great App iPhoneappreviewer13
    Great app I had my first 41C in 1983 I wish the developer would create the survey PAC app                     Great app for surveyors ACA RLS
    Best app ever for an iPhone With this app I have been able to write several programs quickly to solve repetitive things I do all the time This RPN calculator has been improved nicely to even allow more complex problems to be solved It is very easy to use You do need to under RPN but once you do this app is the best Text prompts are also possible                     Great iPhone iPad app Zippy_pop
    For those of us old enough to remember the heyday of the 28S 11C 15C and the 41C VX this is a very nice emulator of the 41CX The one thing that would make it better would be a native iPad mode                     Great emulator cenotaph
    Works as good or better than my old 41c                     Excellent product Momstang
    I love this app and have it on both my iPad and my iPhone I have the real thing sitting on my desk but don t have it with me when I m out shopping Since the prices here are all in Thai Baht I need it to convert Keep up the good work                 Love it JFFA
    This works flawlessly and doesn t lose it s memory or require occasional repairs the way my actual HP41CX does I love it                     Excellent 41CX emulator OWCA-Va
    I love this app I don t use programming I just love knowing where all the buttons are Five stars                     Just like the good old days RTWV
    I have been using the hp51 app for over a year now It works exactly like my old hp41 It looks and feels like it I even played around with the programming of it even though there would be no point and even that they got down to a tee Thumbs up                     HP41cx works great OscarRod
    This works like the original calculator I have been using the app for years now and it has not had an issue yet It brings back the old reliable RPN calculators I know and love I still prefer the physical hp calculator when I have one handy but in a pinch this is the next best thing                     Works well great app NCS
    A blast from the past that should have stayed there If you like RPN calculators there are others that have more documentation than reference to an archival site with scanned pages of original manuals For those who used to use these remembering those days is more useful that this app I m very disappointed with the app Use it for 10 minutes before I deleted it and that s where it will stay     No Documentation jamesjimjimbo
    Behaves great This app acts just like an HP 41 which is one of my favorite calculators                     HP 41 c simulation Gary042
    I bought the printer upgrade and it works good on my iPad but the printer does not appear on the iPhone so beware of the current functionality I am hopeful I can find a solution but if not the iPad app is good in fact very good I am very happy to have an actual HP41 calculator and am currently taking calculus using Larson s 10th but in class I am trying to interface with this app instead of using my priceless 41                     Does What it Says it Will Do GigaPan
    This is my favorite calculator Good news that it lives on Programs and operates like the real thing almost The real thing has better buttons Too bad there is not a card reader or wand app Lots of programs but not a fast way to enter them                 HP 41 Fred191145
    Not quite the real thing as far as how it feels but does the math just fine My fav of several low RPN emulator downloads                 HP 41 review RPN man57
    Love the idea and the interface Big problem in that it locks up regularly on my ipad and the only way i have found to clear it is to power off or hard reset my tablet Cant get it to respond any other way             Great but Lou Weegieb
    My HP 41 CV battery just died after 25 years I was going to try to get the battery replaced but a friend told me about this app I m so excited to have RPN again and on my phone to take everywhere I go Awesome                 Finally an HP app awesome soldmusic
    With the Vintage skin selected the overlays don t align with the keys But really this emulation of an HP 41CX is beyond first rate It s truly astonishing And the great thing about it for someone who does have an actual functional 41CX and a bunch of accessories is that you can evaluate and use a lot of hard to find program modules right here in this emulator Thank you for doing such a great job with this app                     Awesome but there s one little thing rdj999
    Clearly a labor of love This is the HP41C                     Perfect David Thielen
    The GUI is very coarse on retina display It is still iPhone scale and does not use the iPad s full display to give quick access to all of the great functions Most of the skins after an extra 2 99 purchase are very low res and look like scanned and heavily compressed jpegs with compression artifacts The only hi res skin is poorly designed where buttons are indistinguishable from one another making it difficult to find the right one Inverse pinching to enlarge the the calculator image resulted in memory flashing on LCD that would render any further calculations impossible and required a hard reset to fix         Lacking style and versatility Mike25318
    I m fortunate to still have two working 41s but having this app means that I can have all their functionality with me all the time The only thing that keeps this from getting five stars is the fact that it is not made clear from the outset that getting a functioning printer display is an extra purchase The screenshots show what appears to be a functioning stack display when in reality it is only a help screen Kind of a smarmy tactic But I love this app nonetheless Hernando Conwi                 Just Like My 41 Hernando Conwi
    I still have a working HP41c but this allows me to take it everywhere The buttons are a little small on my iPhone but is great on an iPad Well worth the money if you grew up with it                     Great Calculator Wliz231
    My HP 41C slowly developed hardware issues This emulator app is fantastic The developer is responsive and provides rapid support                     Excellent app jneuge
    Love this calculator                     Fantastic Glasairdriver
    Glad to have an emulation of the best calc ever made                     41 is back FrogMan458
    They should be more clear that the modules are not available with the i41CX and you have to get the i41CX for the modules to work Their product description for the i41CX indicates that you have access to all the HP modules So I bought the basic version with an update for overlay It turned out that all modular functions are NONEXISTENT unless you purchase the version I want to return the product if I can         Confusing pricing Pishy90275
    Love the idea and the interface Big problem in that it locks up regularly on my ipad and the only way i have found to clear it is to power off or hard reset my tablet Cant get it to respond any other way           Great but
    Functions and programs beautifully Incredible application I dont miss the real thing at all GREAT JOB DEVELOPERS                 AWESOME
    I bought this version and then upgraded in the app to the extended version This is really well done app by a professional who is standing behind and supporting its further development He helped me understand some of the more complicated configurations possible A sense of the extensibility of the HP41 can be seen by visiting hp41org and hpmuseumorg In my opinion the two best calculators you can put on your iphone are i41CX and 42S I have both                 Superb calculator and developer
    Works just like my old calculator except from my phone I wished they had changed the original digits because they were not easy to read to begin with                 Really an HP calculator
    This is my favorite calculator Good news that it lives on Programs and operates like the real thing almost The real thing has better buttons Too bad there is not a card reader or wand app Lots of programs but not a fast way to enter them              HP 41

    Best calculator app I upgraded to the plus and enjoy the programming Im a pharmacist so it is great to develop programs for ideal body weight calcs as well as kinetics                 Amazing
    Not only was the HP41 the best calculator ever this app is the perfect reproduction of it The thing that really impresses me is that the app creator continually maintains it for new iOS releases fixes any rarely found bugs and adds features Ive used this app since I bought my iPhone 3G and have never had a problem Highly recommended                 Best Calculator Ever
    Amazing HP41 scientific calculator emulation and much more but the pricing structure of the app purchase and InApp purchases is confusing Probably better off to just purchase the features upgrade version from the beginning              Great app confusing features structure
    Not quite the real thing as far as how it feels but does the math just fine My fav of several low RPN emulator downloads              HP41 review

    I love this app I dont use programming I just love knowing where all the buttons are Five stars                 Just like the good old days
    This is a nice app I went to Ohio State U in the 80s when we had one engineering class where the teacher pretty much guaranteed an A if you bought an HP41 series calc Many subsequent teachers in the eng college supported the use of RPN as well I purchased the CX rather than the more popular CV model and it is amazing how used to the calculator I got even though I have had several other HP RPN calcs since When I found this app it was like riding a bike Even though there is no tactile feedback from the ipad one of the things i liked best about the HP the sound feedback in the app does a good job of emulating itits hard to describe The app creator needs to do a better job of describing the selling point of the addon packageswhich may make me purchase              Good replication
    Works as good or better than my old 41c                 Excellent product
    Glad to have an emulation of the best calc ever made                 41 is back

    This is a good trouble free app that emulates the classic HP41C calculator very nicely I prefer it to the standard calculator app on the iPhone                 Nice HP41C emulator
    Clearly a labor of love This is the HP41C                 Perfect
    My HP 41C slowly developed hardware issues This emulator app is fantastic The developer is responsive and provides rapid support                 Excellent app
    This is a great app Better than the original HP41 CX A nice addition would be to show assigned keys when user key is activated                 Great App
    This is a very good RPN calculator In all respects it is the sme as the HP 14CX I had some trouble adding the print option but received good help from the developers I am vey satisfied with the app              Great RPN Calculator
    For those of us old enough to remember the heyday of the 28S 11C 15C and the 41CVX this is a very nice emulator of the 41CX The one thing that would make it better would be a native iPad mode                 Great emulator

    Ive owned a real one used it up and this is in many ways is better For one you can make it go faster than a real one I was surprised at how quickly I could still type and program on this For programming a handheld device actually on the handheld device the keystroke programming calculator model is far superior to regular programming languages and there was never a better calculator than the HP 41 The ability to chain little related programs or call them from each other gives you tremendous flexibility to gain a little mathematical insight on the go I feel like my phone has 10 times the utility from just this one app I have my old friend back Yay                 Brilliant
    It takes too long to start up Nearly 4s on my iPhone 3GS May not sound like a big deal but I find it detracts considerably from the usability Is there some way to make it immediately responsive to user input while any remaining startup processes run in the background Revised February 2010 The new Quick Start feature reduces startup time considerably to less than two seconds on my 3GS Nice work guys                 Very nice but
    A blast from the past that should have stayed there If you like RPN calculators there are others that have more documentation than reference to an archival site with scanned pages of original manuals For those who used to use these remembering those days is more useful that this app Im very disappointed with the app Use it for 10 minutes before I deleted it and thats where it will stay     No Documentation

    Behaves great This app acts just like an HP41 which is one of my favorite calculators                 HP 41c simulation
    As an engineer who still uses a HP41CX and its peripherals in his daily work and also as an experienced FOCAL forty one calculator language programmer this iPad application is outstanding If six stars were allowed this app would get it Its that good After seeing how well the calculator app worked I did the inapp upgrade to get the printer and additional features Thats when the app went to six stars If you believe like me that the HP41CX was the best engineeringscientific programmable calculator ever made and that it was a tragedy that HP quit manufacturing that product you will love this app No more need to buy HP41 items on eBay to keep your years worth of custom HP41CX programs alive just use your iPad running this perfect emulation of the HP41CX                 Outstanding app
    This is a fantastic application My old 41CX 25Years old has been acting up after 25 years of faithful serviceand then I find this app Its a fantastic replacement for my old CX as it has pretty much all the features of the old CX and even a few more The expanded stack readout is a nice upgrade Kudos to the developer of this appits superb                 HP41CX Review
    This app works very well Programming is identical to the 41s with no apparent bugs If you miss or want a 41 for daily use this is a good app to have                 Just like the old 41

    I still have a working HP41c but this allows me to take it everywhere The buttons are a little small on my iPhone but is great on an iPad Well worth the money if you grew up with it                 Great Calculator
    Great calculator Would give 5 stars if buttons were more sensitive You have to be very deliberate about pushing them and it slows you down Also need a vibrate option on button click Currently only does click sound           Buttons need to be more sensitive
    Looks great fast programming is spot on and continuous improvement                 Why not 5 stars
    It seems like a good old HP but I was hoping for a cross product application Can anyone help me perform one on here              Seems good
    Im fortunate to still have two working 41s but having this app means that I can have all their functionality with me all the time The only thing that keeps this from getting five stars is the fact that it is not made clear from the outset that getting a functioning printer display is an extra purchase The screenshots show what appears to be a functioning stack display when in reality it is only a help screen Kind of a smarmy tactic But I love this app nonetheless Hernando Conwi              Just Like My 41
