Also, you don’t have any update for adding Cloud support yet. ### 3/5 — Nice but some fixing *2021-02-28, version 5.3* App is nice but it would be nice if they create an option that allows me to delete. Also sometimes if you click theme or lower keypad the app would freeze and i have to open again so plz fix. ### 1/5 — Some templates doesn’t display properly *2020-07-15, version 5.3* Gave it a one star only because some of the templates aren’t “responding” to the inbuilt browser. ### 1/5 — Unable to open existing files *2020-01-04, version 5.3* Until files can be opened from the cloud it isn’t a lot of use. I don’t like giving negative reviews to developers but I downloaded this to edit XML saved on OneDrive and can’t access them. ### 1/5 — Useless *2019-11-18, version 5.3* All I want to be able to do is import C code files to edit them. All it allows me to do is create new files or import from Photos. Who imports from photos to edit source code. ### 1/5 — Trash *2019-11-09, version 5.3* Ok, so I messed around with JavaScript. So here’s the problem: It always is XML, regardless of if it’s a .js or a XML file. You have to manually fiddle around. Then it resets, so you got to do the above again. So introduce major bug fixes. ### 1/5 — Totally unusable, rubbish. *2019-06-15, version 5.3* As others have said uploading is an issue, but the main problem for me is the menu continually popping open taking up all the real estate on the screen! If I could get past this, I could at least cut and paste each page somewhere! There is simply no way to code whilst the huge keyboard and this menu blocks out everything you’re trying to get a handle on every 1/2 second or so, with no real reason for doing so. I suspect it’s so I hit the ‘Go Pro’ button at the bottom of the menu, but seriously, why would I do that! Has some interesting promised features, some of which aren’t actually there yet. May be a good app one day, but today, don’t waste your time. ### 4/5 — Amazing but one thing... *2019-04-17, version 5.3* I can create web pages on my phone easily and expertly with this app, defiantly one of the best source code editors ive used only one problem tho, all the things i did are stuck in the app. even if its the last update ever to the app, i would love to see a way to export my projects. ### 1/5 — No connections *2019-04-17, version 5.3* Description states you can upload files with ease, but once downloaded the app states this is all still in development. Based on other reviews it seems like this has been the case for some time. Deleted within minutes of downloading. ## Frequently asked questions about Code Master ### What does Code Master do?

I am currently looking into the disappearing of documents issue. I apologize for the inconvenience. Luckily, they are saved somewhere on your device; I just have to find out way to fish them out.
