I have reset the app, but it will not allow me to enter anything via the keyboard, so it makes it sort of useless. ### 4/5 — Good version of the real thing. *2022-03-09, version 2.0.1* Happy the way it works. Only downside is characters on the buttons is rather small. ### 4/5 — Crashes *2021-02-25, version 2.0.0* On an iPhone XS Max, with iOS 13.2.3, after loading it, this calc crashes systematically on hitting any key - in short, it's useless. --- The developer fixed the problem. Now the app is fine. ### 4/5 — So much better! 👍 *2021-02-25, version 2.0.0* The old hp41 rocks again! Looks and works great as HP41CX. Much faster than before. UI is really well done! Having trouble with the HP41CV + Math/Stat pack, but still awesome. Nice update Miroslav! 👏 Will continue using and testing. Old review: “ ... crashes upon first key press on latest update 10/2019 When it worked, it was slow (but free!). Also, I would make buttons larger. “ ### 5/5 — Works now!! *2021-02-25, version 2.0.0* Love this app. Thanks for fixing it! ### 5/5 — No longer functions after 13.3 *2021-02-25, version 2.0.0* Worked fine until iOS 13.3. Now comes up then closes Works now after an update. Thank you! ### 5/5 — Works again!!! *2021-02-25, version 2.0.0* It’s one of the best emulators I’ve used. Will be nice if you add an option for tactile/Haptic feedback for the keys... and the beep ;) ### 4/5 — Program closes after launch? *2020-09-01, version 1.1.0* Prgm closes after launch on my iPhone 11 Pro? Is there an update to fix this problem ? ### 3/5 — Glitching *2020-07-14, version 1.1.0* App closes after launch. Please advise. ### 3/5 — No longer works *2020-02-24, version 1.1.0* This was my favourite calculator app for so long but sadly seems it no longer works under iOS 13. It also seems to be no longer supported or updated. It’s a shame because I always found it the next best thing to a real 41 and far ahead of other calculator apps. I’m sad. ## Most critical reviews (10 lowest-rated) ### 1/5 — HP-41CX *2021-10-04, version 2.0.1* Not functional. Locks up when running a program. ### 1/5 — Doesn’t work *2020-10-17, version 1.1.0* After opening app if I touch the screen, the app closes. It’s useless. I’m using IPod iOS 13.7 ### 1/5 — Does not work *2020-05-20, version 1.1.0* App is unusable :( ### 1/5 — Crashes *2020-03-06, version 1.1.0* Doesn’t work on my iPhone 11 with 13.3.1. Just starts and crash ads immediately ### 1/5 — Crashes on startup *2020-03-04, version 1.1.0* Not fixed yet :( ### 1/5 — Not worth the effort *2020-02-22, version 1.1.0* It’s crap and that’s a wrap. As soon as you touch the screen, it shuts down for no reason. ### 1/5 — App no longer works *2020-02-21, version 1.1.0* I was happy to have found this app since my actual HP calculator has seen its better days. But, like the other reviewers noted, the app closes itself if any button is pushed after launch so that it is no longer usable. Tried deleting and reloading the app but no change. ### 1/5 — Disappointed *2020-01-29, version 1.1.0* Why does the app close when touching the keys? ### 1/5 — Not working now *2020-01-29, version 1.1.0* Just tried it today 29 Jan and when I press the buttons it reverts to the main screen- very disappointed ### 1/5 — Needs a update!!! *2020-01-27, version 1.1.0* Worked great until late 2019. Needs an update as it just crashes on start up!!! ## Most praised reviews (10 highest-rated) ### 5/5 — An excellent emulation of a classic calculator *2026-03-01* This is a beautifully designed emulation of the HP 41C, 41 CV, and 41CX. The look and feel is just like the real calculator and the functionality is perfect. ### 5/5 — Amazing *2024-10-17, version 2.0.1* The first 'program' I ever wrote was on one of these calculators. As a challenge and over 40 years later I tried to solve Project Euler's 1st problem with this emulator... Done! Brilliant. Works perfectly on my phone. Looks like it will run on my iPad too, although the icon seems to be different. Thanks, Love it ### 5/5 — Best Calculator App Ever *2024-10-09, version 2.0.1* I have used and RPN calculator since college and for years used a 41CX. This calculator is the best version I have found for running on my iPhone. ### 5/5 — i feel this is severely underrated *2024-06-25, version 2.0.1* Great emulation of 41c* calculators, haven’t used it in real life, but came around to love it. ### 5/5 — Fix it *2021-02-27, version 2.0.0* This crashes under IOS 13.2.3 !!!!! Is there a fix please I loved it when it was working Thank you very much for the fix ..... I have it working on IOS14.4 PERFECT !!!! ### 5/5 — Application quits after touching screen. Not working. *2021-02-26, version 2.0.0* A was using it for some time and was ok. For some reason now it closes after launch. Any place on the screen being touched makes the application close for no apparent reason. Otherwise it worked fine for me before. Good for me since then. After updated it started to work fine again. Thank you very much. NOTE: One more thing: The keys letters “V” and “W” are inverted when ALPHA mode is switched on. ### 5/5 — Superb *2021-02-26, version 2.0.0* In February 2021 the app was fixed and it works like a charm again. This was a favorite app until IOS 13 when it quit working. I am thrilled to have it back. The GUI is no longer the accurate visual reproduction of if the original HP layout; however the functionality is back! Today I Snoopy-danced with joy. ### 5/5 — Loved it *2021-02-25, version 2.0.0* I loved it while it worked but apparently is incompatible with IOS 13.2 and app support no longer works. It opens but any further attempts to use it resulted in a return to the IOS home screen. Was my favorite but I can no longer recommend UPDATE: downloaded the latest update and it’s my favorite again. IOS 14.4 works great! ### 5/5 — Updated and works well *2021-02-25, version 2.0.0* Updated and now works well. Also has plug in packs available. Thank you! ### 5/5 — Working again! *2021-02-25, version 2.0.0* I have been using this for a while and quite like it. Now updated to work on latest OS. I like how you can select all the different modules that plug in the back. Only minor thing maybe is that when you press keys like Enter they momentarily flash up on the display- my real 41 doesn’t do this. Overall, happy to have it back! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
