A learning app that grew past 200,000 downloads

The challenge

The goal was a learning app that felt fast and native on both iOS and Android without the cost and drift of maintaining two separate codebases. It also had to work when connectivity didn't — learners don't always have a stable connection — and it needed to earn revenue through in-app purchases while staying simple enough to grow over time.

What I built

• One React Native + Expo codebase shipping to both the App Store and Google Play, with native polish where it counted.
• Offline-first content so lessons keep working without a connection and sync cleanly when it returns.
• In-app purchases for premium content, wired to the stores and handled reliably across platforms.
• Analytics to see how real users move through the app, so decisions were driven by behaviour, not guesses.
• A maintainable, typed codebase that supported ongoing releases as the user base grew.

The result

The app grew past 200,000 downloads with roughly17,000 active users, running on a single shared codebase across both platforms. Just as important, it stayed maintainable — new features and fixes shipped without the whole thing becoming fragile, which is what lets an app keep compounding instead of stalling after launch.

The takeaway

Cross-platform done well isn't a compromise — it's how a small team (or a solo founder) reaches both stores affordably and keeps shipping. If you're planning a mobile product, I can take it from idea to launch and stay on for the growth phase.
