Radio Umiłowani Mobile App

Radio Umiłowani

Challenge

Radio Umiłowani is a hobbyist Catholic internet radio station whose listeners could only access the stream through a browser — on mobile this was inconvenient and prevented background playback. The client needed a dedicated mobile app for iOS and Android: easy to use, with background audio playback and the ability to show dynamic messages managed by the administrator.

Solution

We built the app in React Native with Expo, running on iOS and Android from a single codebase. We implemented HTTPS audio streaming with background playback support, visual animations (pulsating logo, 12-bar sound wave, "LIVE" badge) and a custom Express.js mini-backend for message management. The app itself took 2 weeks to build — the biggest challenge was the App Store and Google Play review process, which together took about 3 weeks.

HTTPS audio streaming with buffering and connection error handling
