Launched my iOS app - Tuneo Offline Music Player

#showdev #reactnative #ios #typescript

🚀 Just released my iOS app!

🎧 It’s called Tuneo — a clean, ad-free offline music player for iPhone.

I built it for myself because I couldn’t find a good way to play my own MP3s without ads or login walls.

Now it’s live on the App Store, and I’d love for you to try it!

📱 Import your own audio files
🎶 Edit tracks, manage playlists
📴 100% offline + runs in the background
🚫 No ads, no tracking, no login

App store: https://apps.apple.com/us/app/offline-music-player-tuneo/id6748915689

Website: https://tuneo.arcade.build/

Tech Stack

Built with React Native + Expo, using:

  • expo-router for navigation
  • react-native-track-player for audio playback
  • expo-file-system, expo-media-library, and expo-document-picker for importing and managing files
  • zustand for global state management
  • shopify/flash-list for performance-optimized lists

And several other libraries for UI, blur effects, gestures, icons, and font support

No backend, everything runs locally on-device.

Challenges Faced While Building Tuneo

  • Migrated from expo-audio to react-native-track-player to enable background audio and lock screen controls.
  • Built a custom queue system with support for history, shuffle without immediate repeats, and repeat modes.
  • Redesigned file storage architecture to avoid duplication and provide better user access via the iOS Files app.
  • Used zustand with multiple stores to separate concerns and avoid race conditions in state management.
  • Resolved iPad modal presentation issues by dynamically using fullScreenModal on iPad and modal on iPhone.
  • Switched from FlatList to Shopify FlashList to ensure 60fps performance with large music libraries.
  • Wrote detailed iOS permission descriptions to pass App Store review for file access and audio playback.
  • Implemented support for multiple audio formats (MP3, FLAC, WAV, AAC, OGG, M4A) with robust error handling.
  • Iterated import system from manual picking to batch import, folder scanning, and duplicate detection.
  • Added reactive storage calculations to show real-time, accurate file space usage.
  • Handled iOS audio session interruptions (calls, other audio apps) to maintain seamless playback state.
  • Integrated native modules using Expo Dev Client and EAS build config for full native feature support.

Conclusion

Thanks so much for reading and if you give it a try, thank you even more. Just an indie dev trying to build something useful!!
