Vibes Player - Sell Project

Vibes Player — Android Music App (Source Code + Live Play Store Listing) Asking price: Negotiable Overview Vibes Player is a fully built, live Android music app on Google Play that combines offline local playback with internet radio, synced karaoke-style lyrics, and a 10-band equalizer. It's published, working, and actively maintained — ready for a new owner to take over and grow rather than build from scratch. Why I'm selling I built this alongside school, and I can't give it the ongoing time it deserves anymore. Looking for someone who can actually invest in growing it. Key features Offline playback: MP3, FLAC, WAV, AAC 10-band equalizer, bass booster, 3D virtualizer, volume/loudness normalization Synced lyrics with full karaoke mode, offline lyric caching, custom lyric import Internet radio: browse by country/genre, search, favorites, recently played Custom themes, player skins, audio visualizers (album-art adaptive) Playlist management, folder browser, tag editor with artwork fixing No account or cloud library required — offline-first for local playback Current status Live on Google Play, Music & Audio category, rated 3+ 50+ downloads Ad-supported (Unity Ads) Actively maintained — last updated August 2026, version 2.2.1 (11 builds deep) Privacy policy and full store assets (icon, screenshots, description) already in place Technical highlights 45,000 lines of Dart across 141 files, organized into clean provider/service/DAO layers Native DSP-based equalizer built on Media3/ExoPlayer (not a simple preset filter) Local SQLite persistence (sqflite) with dedicated DAOs for tracks, albums, artists, playlists, and history Firebase Crashlytics + Performance monitoring already wired in Forked/patched copy of the justaudio package (MIT licensed) for custom playback behavior What's included Full source code and version history App transfer via Google's official process (buyer will need their own Play Console developer account — one-time $25 Google registration fee) App icon, screenshots, and branding assets Signing credentials and Firebase project access handled securely at closing (not included in the public source dump) [Optional: offer a set number of days of email support during handover] Tech stack Flutter/Dart (Flutter 3.44+, Dart SDK 3.6+), with a native Kotlin/Android module for the equalizer DSP layer (Media3/ExoPlayer). State management via Provider; audio via justaudio + audioservice. Ideal buyer A developer or small team who wants a working, already-published music app with a genuinely built-out feature set to extend — rather than starting from zero. The equalizer, lyrics engine, and radio integration alone usually take a solo developer months to build. Contact: andereya8@gmail.com
