Built & Monetized 2 Native Android Apps using Kotlin & XML (Quiz Prep & 2D Arcade Game) - Sharing my experience & looking for feedback!

Hey everyone! As an indie developer, I recently built and deployed two native Android applications using Kotlin and Android Studio, focusing on performance and monetization integration.

1. Tech & Placement Quiz App

• Features: Curated questions covering DSA, Core CS, Quantitative Aptitude, and Current Affairs. Built with dynamic deduplication logic using SharedPreferences to prevent repeating questions in sessions.
• Monetization: Integrated Start.io (http://Start.io) SDK.
2. Sky Dash (2D Arcade Game)

• Features: A smooth 2D flyer game built with custom GameView frame-rate physics and dynamic obstacle generation.
• Monetization: Integrated Start.io (http://Start.io) / AppLovin SDKs.
Links & Playable Versions:
