This app is excellent but without an autosave and the constant crashing makes it unusable. ### 3/5 — Have paid for it. Still have ads, disk icon still unavailable *2024-06-13, version 2.5.2* Have paid for it. Still have ads, disk icon still unavailable. Website is unavailable. Works good otherwise. ### 4/5 — It works as intended. *2024-04-23, version 2.5.2* The last app I had kept bugging out. ### 5/5 — Amazing *2022-03-16, version 2.5.2* It can not only code in c but also python, c++, and JavaScript!!! ### 5/5 — Unbelievable coding app *2022-03-02* I never thought such a software would exist. It has an issue with python tkinter library (can’t import it from its Python3 interpreter). But, everything is so wonderful I gave it a “5 stars”. ### 5/5 — The best *2021-11-25* Granted this is the only iOS compiler I’ve used, it’s the only one I will use. I’ve been using it to write a little VM project in my spare time, in Python. It also supports Lua, which I’m starting another project in. The editor is phenomenal, offering native keyboard and a programmer-friendly default keyboard, which even has an expanded mode for maximum efficiency at the cost of screen space. Also has mouse/touch cursor control buttons for highlighting text and precision cursor positioning. In addition, easy to access buttons are given to cut, copy, and paste text, a save button, undo/redo buttons, and a run button. My thanks to the author, who went above and beyond in providing an outstanding app. ### 4/5 — Good App *2021-06-15, version 2.5.2* I went on a 2 week vacation with my family and over the last 6 months I have been learning C and this was a great tool to use for my vacation (I didn’t bring my laptop). I could enjoy my vacation and code at the same time . ### 5/5 — Awesome & Very Usefull *2021-01-20, version 2.5.2* I love this app very much.No problems at all,never crashes and is the only app to f it's kind that I could find.All in All a name nice app. ### 3/5 — Error with try-catch on C++ *2020-10-27, version 2.5.2* This compiler has issues with try-throw-catch on C++. Even when the code is designed to catch all exceptions, the compiler prints an error message of “uncaught exception” when an exception is thrown. When I copied the same code and tried it on another compiler, the exception was successfully caught, so it’s clearly the issue with this app. ### 5/5 — Real C/C++ Compiler on my iPhone *2020-10-24* I finally found the real deal. This lets me create, run and save C/C++ files. Then the files can be copied anywhere (to a computer for example) using the iOS Files app and sharing the file. Amazing! ### 4/5 — Making and linking libraries *2020-09-06* There should be a clear text file explaining how to create linkable object files. I may have to find another product that makes that clear. Otherwise I like this learner system, though I have long years in the past doing C coding at the firmware level; this is a polished refresher tool. It works great otherwise than the matter of user defineable libraries. It would be 5 stars, but for the library mystery. ### 3/5 — Love it but needs updating *2020-08-29, version 2.5.2* I’m loving this app as its lets me write some code directly on my ipad. The UI just needs some updating, support for dark mode, and multi window support please. I’ve encountered a couple bugs though, the most recent one is this. Running this code in C does not produce the same output on other compilers: printf("*\t* ***** *\t* *\t*\n**\t* *\t* * *\t*\n* *\t* *\t* *\t" " ******\n* ** *\t* * *\t*\n*\t* ***** *\t* *\t*\n"); ## Most critical reviews (10 lowest-rated) ### 1/5 — Real review *2024-05-28, version 2.5.2* This app is trash ### 1/5 — cs50 file not found *2020-08-19, version 2.5.2* when i type #include and run the code it says file not found ### 1/5 — Non-starter *2019-08-07, version 2.5.2* Copy -paste simply does not work as one would expect , as such being “mobile let me check “ it is simply useless . Imagine you read a c++ article on internet and would like to try out the sample code from that article . You cannot do that, you actually have to type the whole thing , which is ridicules and quite stupid , hence, as I understand it would be most common use case . What the hell the developer was thinking ?!! ### 1/5 — Buggy and stinks *2016-04-24, version 2.0.8* I'd give it no stars at all. Can't handle the %d function without glitching up. stay away. ### 2/5 — okay, but not very useful *2024-08-18, version 2.5.2* it’s sorta ok, and has some useful editing features for writing code on a mobile device, but seems to lack extremely fundamental libraries like iostream and vector. would be hard to make anything much more than Hello World with this app. ### 2/5 — Promising until.. *2023-02-20, version 2.5.2* Interface was good. Might just be me but I couldn’t get it to build multiple C files together into one program. This severely limits what can be done. ### 2/5 — not so worth it *2022-11-25, version 2.5.2* There is little provision for exporting files and no provision whatsoever to import files. ### 2/5 — Oooh idk… *2022-06-07, version 2.5.2* This app UI reminds me of windows XP. It would’ve been better if you update it sth. ### 2/5 — compiler has a problem *2021-01-07, version 2.5.2* I had a problem executing a command and my teacher told me that my phone compiler has a problem, please check this immediately.🙏🏻🙏🏻 Tnx🌻 ### 2/5 — Mobile Programming (Kinda) *2019-06-13* I have been enjoying learning C and wanted to have a method that I could use for programming on the go. This application has a lot of potential. I have however run into an issue with the implementation of string.h which renders “strcmp” useless. I’m hoping that this can get repaired in a new version of the app so that I can continue programming on the go. I did try to log this on the developer website however I was never able to register and subsequently provide my feedback. Some sort of registration issue. ## Most praised reviews (10 highest-rated) ### 5/5 — Best c app I’ve seen on the App Store *2024-07-21, version 2.5.2* Trying to figure out open gl it says it’s compatible ### 5/5 — Has everything I need *2024-07-19, version 2.5.2* - Standard libraries - File system - Compiler - Works offline ### 5/5 — Good *2024-01-29, version 2.5.2* As far as I can tell, this is the only non cloud based C/C++ compiler for iPhone. And it is free? Amazing -- just what I wanted. It's pretty good, too. ### 5/5 — Absolutely amazing! *2023-09-30* This app has been incredibly useful when I'm on the go and want to write a quick program or two. The ads aren't invasive at all and the app just works beautifully! Definitely easy to use and I would recommend it to my friends. If I weren't so broke I would buy the pro version to support the developer ;) ### 5/5 — Best app *2023-08-08, version 2.5.2* Best c compiler. It was so good the Chinese government jailed the author. ### 5/5 — Great app! *2023-07-26, version 2.5.2* This app is great, it runs your code without internet, I recommend you all to download it!. ### 5/5 — The best I could find. *2023-05-21* I’ve just started using this compiler, but already love it and I would like to thank it’s creators for the excellent work. If only it supported Swift! ### 5/5 — Well Done - Best On-Device Compiler *2023-04-22* In addition to being such a wonderful app, it has the most unobtrusive ads I’ve come across. Also wanted this review to double as a call for help to reviewer BigPirhana who noted on Jun 19 the discovery of a file that unlocked the ability to write multi-sourced projects. Hope it’s not bad form to ask the name & location of the file. Thanks! ### 5/5 — Simple put it just works! *2022-12-24, version 2.5.2* Wow, so well designed. It’s easy to use and a joy to use. I can lay in bed and play around with code that I’m working for microcontrollers like the ESP32 ESP8266, etc. And for the most part it’s free. I would be happy to pay ten bucks for this app. Definitely a 5 star app!!! ### 5/5 — Long time user wanted to say thanks *2022-06-19* I have been coming back to this app for that last few years, anytime I’m trying to experience my with doing c++ on iPhone I always think about this app. I almost gave up on it, until I found the file that unlocks the ability to write multi-sourced projects, ever since than nothing has been able to compete on iPhone. Add some git support and I am able to take some pretty power apps with me! Thank you, and this has helped me get through a whole CS program since COVID started. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
