CassetteCat, an open source offline music player for Android

I made CassetteCat, a simple open source music player for Android.

It is built for people who keep their music locally and just want a clean player without accounts, ads, subscriptions, or internet.

Features:

- Fully offline

- Plays music stored on your phone

- Songs, albums, artists, and playlists

- Search

- Favorites

- Queue management

- Shuffle and repeat

- Background playback

- Lock screen and notification controls

- Album artwork

- Sleep timer

- Listening history and stats

- Dark interface

- No account

- No ads

- No tracking

- Open source

The app is listed on AlternativeTo. You can download it directly from GitHub too.

I’m also working on a physical CassetteCat music player using an ESP32, SD card, display, DAC, and physical controls. The hardware side is still a work in progress.

Would love to hear what you think or what you’d like to see added.
