Just like most other coding apps out there, it is not perfect to develop real-world projects, but quite useful if you want to test some code snippets.

How to write programs and compile them using Online Compiler Android app

The app is pretty straightforward. Just install it from the Play Store using the link provided below. The app uses powerful cloud servers to execute code which helped their development team to keep the size of the app to below 2 MB which makes the app lightweight as well. Big kudos to them for this!

After installing the app, simply select a programming language form its menu, as shown below, and start writing the code in its IDE.

Once you have written the code, compile it to see the results in its Output screen. Best of all, if your program requires any inputs, then the app will prompt you to enter values, as you can see in the screenshot below.

If your code is successfully compiled, then you will see the results in the Output screen, as shown below. Like most compilers and coding apps, it also flags errors, type of error and line number which triggered the error, so that, you can easily fix it. Online Compiler makes it pretty easy with its reading mode which makes code inspecting a lot easier task.

Do note that you online require an internet connection to execute the code. That means even if you are running out of your data pack, you can still practice your coding skills in this app. As the app automatically saves the code files, you can execute the program whenever you connect to the internet.

The app also lets you switch between light and dark themes. So if you don’t like the default light theme of the IDE like many other developers out there, you can easily switch to the dark mode from the settings.

Additional Features:

  • Intuitive and decluttered interface which allows you to easily pick a programming language and write code as quickly as possible.
  • Dark and light color themes work as Day/Night modes
  • You can also open your existing code files within the app.
  • Auto Save ability on the go.
  • Reading Mode to inspect your work.
  • Share your code files in written text mode.
  • Text Wrapping mode included.
  • ‘Quick Access’ or ‘Tab’ allows you to quickly insert special characters.
  • Save coding in your local storage as file extensions of all languages.
  • Output Tab enables you to see your coding live and fast.
  • Code Syntax Highlighting

The Verdict:

All these features are perfect, but I really missed the feature to save coding files/projects on the cloud but that won’t really affect its usability as it offers everything to let anyone code on the go and see code snippets in actions.

While on the hunt, I looked up all possible alternatives for Online Compiler. There are many other similar apps but none of them could beat Online Compiler as it supports more number of coding languages and is lightweight at the same time.

We reviewed –

  • Terminal IDE – Which was mainly focused towards Web Development with full Java/C/C++/HTML Development although with more fluidity than Online Compiler but you won’t switch between two apps when you already have it covered in Online Compiler.
  • DroidEdit – Content and source code editor (like Notepad++ on the PC) and is accessible for Android tablets and smartphones. It additionally supports an assortment of languages like C, C++, C#, Java, HTML, CSS, Javascript, Python, Ruby, Lua, LaTeX, and SQL.
  • Syntax Highlighted Code EditorSupports HTML, CSS, JavaScript, PHP editor, Python, Java, C, C++, CoffeeScript, Haskell, Clojure, and Groovy.

While these apps are promising on their own features and languages, I personally would recommend anyone to go for Online Compiler because of its nature and work environment allowing you to write codes offline and flawlessly.

The app works as a great example for beginners as well who want to enhance their coding skills.
