AppSignal — Track your app’s health, errors and performance with ease

Track your app’s health, errors and performance with ease

Hey Product Hunt! 👋 I’m Bala Krishna, the creator of CodeVarsity. I built this app to solve a massive frustration: most coding apps are just glorified textbooks. They teach you the theory, but when it’s time to actually write code, you have to switch to a computer. I wanted to change that. CodeVarsity is a complete, offline Mobile IDE built for learning. Here is what makes it different from standard tutorials: Real Coding: Write, compile, and run Python, Java, JavaScript, and Go directly on your phone. 100% Offline: The compiler runs locally. No internet required. Code on the subway or a flight. Custom Keyboard: We built a specialized keyboard specifically for coding (easy access to brackets, tabs, and operators). Interactive Learning: Master logic with 30+ visualizers and gamified challenges like "Bug Squasher". Whether you are starting your first Python script or brushing up on Java data structures, you can now do it entirely from your pocket. I would absolutely love your feedback on the UI, the custom keyboard, or the course structures. I’ll be here all day answering questions and taking feature requests! Happy coding!
