A collapsible glass sidebar with its own blur tuning, a split player layout, side-by-side lyrics, and a capped-width mini player so controls stay in reach instead of stretching across 12 inches.
for the people who ask what it's made of
under the hood
- ui
- Jetpack Compose with MVVM. Screens live in ui/screens, wired through a single NavigationBuilder.
- liquid glass
- Modifier.liquidGlass(...) over a vendored copy of Kyant0/backdrop. A rememberLayerBackdrop() captures real pixels; any surface holding that reference can sample, blur and refract them.
- playback
- A Media3 ExoPlayer foreground service — notification and lock-screen controls, Android Auto, gapless and crossfade.
- data
- Room for the local library, DataStore for preferences. The innertube module talks to YouTube Music and is kept out of the app module entirely.
what's new in v1.4
- In-app updates fixed: Check for updates now finds Convx's actual APK and downloads it directly — no more bouncing to the browser.
- All font controls in one place — Settings → Appearance → App Font: the App Font picker, the Display font toggle, and the Custom font installer.
- Choose a bundled typeface for the app's display text: Google Sans, Sans Flex, Outfit, or Plus Jakarta Sans (Settings → Appearance → App Font), with a live typography preview.
- Choose System Default to use the system font, or a custom-installed font.
- Auto-DJ Mixing plays songs back-to-back with tempo-matched crossfades: the incoming song's speed is gently nudged to match the outgoing one while they blend, so the mix stays locked to a beat.
- How to use: Settings → Player → turn on Crossfade first, then enable Auto-DJ Mixing. It uses on-device BPM detection (no internet) and falls back to a plain crossfade when a song's tempo can't be detected or is too far off.
- New dedicated ArchiveTune-style full-screen lyrics presentation.
- One-tap flow: Settings → Player → One-tap full-screen lyrics.
- Player controls collapse to the top (or bottom, your choice): Settings → Player → Collapse controls upward.

faq
Yes. Convx is free and open source under GPL-3.0. There are no ads, no subscription and no paid tier — support is entirely optional.
Android 8.0 (Oreo) and above. The Liquid Glass effects scale down gracefully on older or slower devices.
No. Convx is distributed as an APK through GitHub Releases. Download it from this page, allow install from unknown sources, and the built-in updater handles every version after that.
No. There is no telemetry, no analytics and no account. Your library, listening history and settings are stored locally on your device and never uploaded.
Open Android Auto, go to Settings, tap the version number repeatedly to unlock Developer settings, then enable 'Unknown sources'. Restart Android Auto and Convx will appear.
Convx streams from YouTube Music through an unofficial InnerTube client. It is not affiliated with, endorsed by or associated with YouTube or Google LLC in any way.
Open an issue on GitHub, or drop into the Discord — both are linked at the bottom of this page. Pull requests are welcome too.
