🚀 I just published my first Kotlin app — would love your feedback!
Hey everyone!
After months of learning Kotlin + Jetpack Compose, I finally released my first Android app on Google Play:
👉 Programming Quiz Guide
Test your knowledge in Java, C++, Python, Angular & more — with explanations after every answer.

🎯 Why I built this
I’ve been teaching myself Android development, and I wanted a project that:
- helps me practice Kotlin, Compose, ViewModels, DataStore, ads, in-app review, etc
- is useful for other developers
- is fun to play and easy to expand
I also personally enjoy learning through quizzes, so I decided to build a developer-focused quiz app.
🔧 What’s inside
- Each category has levels that gradually increase in difficulty:
- C++ Foundations
- Java OOP
- Python (Basics → OOP)
- Angular (Basics → Advanced)
- Web Development Fundamentals
🧰 Tech Stack
- Kotlin
- Jetpack Compose
- Material 3
- ViewModel + StateFlow
- DataStore for saving progress
If anyone is interested, I’m happy to share code snippets or explain how I implemented anything.
💬 Thanks!
If you have a moment to try it or leave a review, it would mean a lot.
Happy to answer any questions about how I built it — maybe it helps other beginners too!
Thanks for reading 🙌
