What is Levyra?

Unlike typical wrapper or web-reskin apps, Levyra is a native, ground-up Android audio application. It queries, resolves, and streams music dynamically using YouTube Music's InnerTube API with a LevyraExtractor-powered fallback, routes audio via an optimized AndroidX Media3/ExoPlayer background service, and outputs full tracks straight into your local storage.

Every track you download is fully parsed, tagged, and structured as a clean M4A file in your system Music/Levyra directory, complete with embedded metadata, titles, artists, and album artwork.

Key Features

- Offline Export Pipeline 📥 - No Cache Blobs: Exports actual media files directly to the public Music/Levyra directory. - Pure-Kotlin Tagging: Embeds high-res album covers, song titles, album names, and artist metadata on completion. - WorkManager Daemon: Background tasks persist through system reboots, handling network changes with smart retries. - Truncation Shield: Rigid Content-Length checks discard corrupted or incomplete files and schedule auto-retries.

- Stream Resolving & Search 🔍 - InnerTube + LevyraExtractor Resolver: Dual-channel media resolution with smarter Opus/M4A selection, fresh URL caching, and stronger fallback when YouTube changes stream signatures. - Intelligent Caching: TTL-based playback stream cache prevents duplicate server requests and speeds up loading. - Smart Search: Predictive search suggestions, categorized filters, and instant top-result matching. - Prefetching Engine: Ahead-of-time loading for top charts and queued songs to guarantee zero-gap playback.

- Listening Pulse — Private Stats 📊 - On-Device Listening Statistics: Listening-session metrics used by Pulse are stored locally in Room and are not uploaded as analytics or developer telemetry. Search, artwork, lyrics, playback, SponsorBlock, and optional account features still contact third-party services and may transmit ordinary network/request data. - Pulse Dashboard: Total minutes, plays, day streak, completion rate, peak listening hour and a 7-day rhythm chart inside the Library. - Top Artists & True History: Most-listened artists ranked by real playtime plus a history of what you actually played, not just what you searched.
