Guppy: Local music player

Guppy is a local music player for people who keep their own song collection and want a clean, reliable way to listen anywhere. Build a personal music library on your iPhone or iPad, import tracks from the sources you already use, and play them offline without depending on a streaming subscription.

Bring in music your way
Import songs from the Files app, WebDAV servers, Wi-Fi Transfer, or a Navidrome/Subsonic music server. Add albums from your computer, NAS, or self-hosted library, then keep everything available on your device for offline playback. Matching lyric files can be imported alongside your songs, so your library stays complete.

Organize your collection
Browse your library by songs, albums, artists, and playlists. Keep favorites close, revisit recently played tracks, and build playlists for daily listening, focused work, travel, or any collection you want to keep separate. Guppy is designed for people who care about their own files and want them to feel at home on iOS.

Follow the lyrics
Guppy supports synced lyrics for a more expressive Now Playing experience. Watch lines move with the music, keep the current lyric in focus, and enjoy a dedicated lyrics view that works naturally while you listen. It is built for LRC-style lyrics and local music collections where the song and words belong together.

Shape the sound
Use the built-in equalizer to adjust playback for your headphones, speakers, or listening mood. Add space with reverb controls when you want a wider sound. Guppy keeps these audio tools close to the player, so you can tune your music without leaving the listening flow.

Made for local playback
Guppy supports a wide range of audio files, including common formats such as MP3, AAC, M4A, WAV, AIFF, FLAC, OGG, Opus, APE, WMA, and more. The player is built for background playback, lock screen controls, a mini player, queue control, and a focused Now Playing screen that feels at home on both iPhone and iPad.
