Yuyin: Music Diary

Some songs leave more than a melody. Yuyin is a private music diary for the moments you want to keep: play local audio, follow the lyrics, move precisely through a track, and attach a note to the exact second that stayed with you.

No account is required. Import audio from Files or scan the music already on your device, then revisit your saved songs, timestamps, and reflections in one quiet archive.

Features:
• Background playback with lock-screen and Dynamic Island controls
• Lock-screen artwork with a branded fallback when no album cover is available
• Repeat one, repeat all, sequential playback, and shuffle
• Draggable progress control with elapsed and total duration
• Prominent lyrics and animated vinyl playback
• Notes tied to the current song and playback timestamp
• Local library scanning and Files import
• English and Simplified Chinese support

Private by design:
Yuyin does not create an account, upload your diary text, or send imported songs to a server. Your song notes, playback positions, imported audio, and settings stay on this device.

Yuyin is made for late-night listening, small reflections, and the songs that stay with you after they end.
