Doppler
An album-focused music player for the MP3, FLAC and other audio files you already own
by Brushed Type Ltd · listed Oct 19, 2026
Quick verdict
Worth installing if you own your music as files and want a tidy offline player on iPhone. If you only stream, it has nothing to offer, since it cannot pull in Apple Music content.
Best for iPhone owners with a library of MP3, FLAC or other downloaded music who want an offline, album-first player instead of streaming.

Doppler review
Doppler is a music player for iPhone and iPad built around your own library rather than a streaming catalogue. You bring in music files such as MP3 and FLAC, and Doppler organises them into a clean, album-centred collection you can browse and play offline. It suits people who buy downloads, rip their CDs or keep a lossless archive and want somewhere better than the Files app to listen to it.
Why we picked it: It is one of the few well-designed, actively developed iOS players aimed at owned music files, with a focused layout that puts albums first and a solid rating from App Store users.
Watch out for: There is no streaming catalogue, so you need to supply your own files. The download is free, but full use may require an in-app purchase. There is no Android version.
What we like
- Plays FLAC, MP3, WAV, AAC and M4A files offline
- Album-first layout with recently added albums and full library search
- Edits song and album metadata and fetches missing artwork on the device
- Imports files from Safari, Dropbox, Google Drive or a computer over WiFi
- Supports AirPlay 2, Bluetooth, CarPlay and Last.fm
What could be better
- No streaming catalogue, so you must supply your own files
- Cannot import songs or playlists from Apple Music
- Free download may require an in-app purchase for full use
- iPhone and iPad only, with no Android version
Questions about Doppler
Is Doppler free?
The download is free, but the app is freemium, so unlocking everything may require an in-app purchase. Check the current pricing in the App Store before relying on it.
Does Doppler work offline?
Yes. Music and playlists are stored locally on your device, so playback works on flights or the metro without a connection.
Which audio formats does it support?
It handles FLAC, MP3, WAV, AAC and M4A, along with several other common formats.
Can I use my Apple Music library in it?
No. Doppler plays local files only and cannot import songs or playlists from Apple Music or other streaming services.
Is there an Android version?
No, Doppler is available for iPhone and iPad only. Android users would need a different player for their local files.
