Features
Read full description

Write Kotlin code directly on your iPhone, iPad and iPod Touch! This app is ideal for learning and testing code snippets! Kotlin is a cross-platform, statically typed, general-purpose programming language with type inference. Kotlin is designed to interoperate fully with Java, and the JVM version of its standard library depends on the Java Class Library, but type inference allows its syntax to be more concise. Kotlin mainly targets the JVM, but also compiles to JavaScript or native code (via LLVM). Kotlin is sponsored by JetBrains and Google through the Kotlin Foundation. Features: - Compile and run your program - View program output or detailed error - Custom keyboard for easy input of frequently used characters - Optimized for connecting with external physical/bluetooth keyboard - Advanced source code editor with syntax highlighting, bracket completion and line numbers - Open, save, import and share Kotlin files. Limitations: - Internet connection is required for compilation - Maximum program running time is 20s - One file can be run at a time - Some file system, network and graphics functions may be limited - This is a batch compiler; interactive programs are not supported. For example, if your program provides an input prompt, enter the input in the Input tab prior to compilation.

Verdict

The call

The clearest difference is in-app purchases: Campus Labs® Event Check at none against Kotlin Programming Compiler's 1. Campus Labs® Event Check also leads on ads (none vs shown) and ratings volume (1.5K vs 7). Kotlin Programming Compiler's advantage is review sentiment (56% vs 43%) and iOS requirement (12.0 vs 15.0). On price, update cadence and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Campus Labs® Event Check holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Campus Labs® Event Check has 1.5K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 43% of Campus Labs® Event Check's written reviews are positive against 56% of Kotlin Programming Compiler's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Campus Labs® Event Check ships an update monthly, Kotlin Programming Compiler every 2 months. Both last shipped on November 2, 2026.
