Every Jetpack Compose widget, every Kotlin pattern, and every popular app UI you'd want to study — searchable, playable, and ready to copy into your own code.
Whether you're new to Compose, brushing up before an interview, or rebuilding a UI you saw in the wild, ComposeLab gives you the lesson, the working demo, and the source — together, in one place.
WHAT'S INSIDE
• Component playground — every Material 3 widget with a runnable example, the code snippet, and a tweak-and-preview playground. • Real-app demos — production-quality reimplementations of Instagram, TikTok, Spotify, Gmail, YouTube, Twitter, Movies, Crypto, Dating, Paint, Meditation, Onboarding, and more. • Interview Prep — 400+ Kotlin & Compose questions across Beginner and Intermediate decks, with a Daily Question to keep your streak alive. • Quiz Engine — 350 multiple-choice questions across 10 topics. Four modes: Daily, Timed, Topic-wise, and Mock Interview. Earn XP, build streaks, and level up from Beginner to Grandmaster. • Learning Resources — a curated reading list of docs, courses, and articles, opened directly in your browser. • Showcase — Compose CookBook–style ports for animations, lists, ConstraintLayout, MotionLayout, dynamic UIs, and more. • Bookmarks & Recently Viewed — save what you want to revisit; pick up where you left off.
BUILT FOR
• Android developers learning Jetpack Compose and Material 3. • Kotlin learners who want runnable examples, not just docs. • Engineers prepping for Android interviews with MCQs and Q&A. • Anyone who wants to see how popular apps are built in pure Compose.
DESIGN & UX
Built entirely in Jetpack Compose with Material 3, dynamic color support, and a polished light/dark theme. Edge-to-edge layouts, smooth animations, and a floating bottom-bar that gets out of your way.
AD-SUPPORTED, AD-RESTRAINED
ComposeLab is free. The app shows a single banner ad at the bottom of the screen and an occasional App Open ad on launch — never inside a lesson body or an interview question. That's how we keep updates coming without charging you.
PRIVACY
ComposeLab is privacy-first. We collect only what's needed to keep the app stable: anonymized device identifiers for crash grouping (Firebase Crashlytics), aggregate feature-usage counts (Firebase Analytics), and advertising signals served by Google AdMob. Full details are in the in-app Privacy Policy.
