Doppler

About

Doppler is a music player for people who still own their music. Drag in MP3, AAC, M4A, FLAC, ALAC or WAV files and they just play, no conversion, no cloud account, no streaming upsell. It quietly fixes the tedium of a local library too: Artwork Search finds missing covers, Merge Albums stitches multi-disc releases together, and Liked Songs and Recently Added views keep everything organised.

Doppler Transfer moves music between Mac and iPhone over WiFi, USB or AirDrop, sidestepping iTunes-era syncing entirely. Made by Brushed Type, the Mac app reached version 3.2 in October 2025 and runs on macOS 11 Big Sur or newer. It costs $30 as a one-time purchase with a free trial, which feels exactly right for software built around ownership.

Alternatives

  Pick Swinsian if you have a very large library and want folder watching and advanced tag editing: it is $34.95 to buy, with a free trial to try first.

• VOX

  Pick VOX if you want a free FLAC player to start with: the Mac app is a free download on macOS 10.15 or later, and VOX Premium adds music sync between Mac and iPhone.
