Entrain vs. Brain.fm
Last updated June 2026
The short version: These two aren't really the same product. Brain.fm streams AI-generated functional music engineered for focus and sleep — it modulates music rather than generating bare tones. Entrain generates true binaural beats and isochronic tones with an exact frequency you control. Want polished, engineered music across every platform? Brain.fm. Want pure, adjustable entrainment frequencies you can try free? Entrain.

Where Brain.fm wins
Brain.fm has a large, professionally produced music library that many people find far more pleasant to listen to than bare tones — a real advantage if hours of pure sine waves aren't your thing. It's cross-platform across iOS, Android, and web, and its focus-session design is well thought out, with a science-oriented brand built around getting into deep work. If you want a finished, music-first experience that just plays, Brain.fm is a strong choice. Check its current listing for the latest pricing and platforms.
Where Entrain wins
- True, controllable entrainment. Real binaural beats and isochronic tones with an exact, adjustable target frequency you set — not curated music.
- On-device & offline. Frequencies are generated live on your device, fully offline, with no account and nothing streamed.
- Lower price. $4.99/mo or $44.99/yr with a 7-day trial, plus a free web player to try first.
- Apple ecosystem reach. A standalone Apple Watch app and a native Mac app, with one subscription across iPhone, iPad, Watch, and Mac.
Honest take
This is tones versus music, not better versus worse. If you want engineered, listenable functional music and you're on Android or the web, Brain.fm is the right tool. If you want pure, precise, controllable entrainment frequencies — generated on-device, offline, and free to try — Entrain fits better. The cleanest test is to play Entrain's binaural and isochronic engines free for a few minutes, then trial Brain.fm and feel which experience suits you.
