A Brain.fm alternative with music that never repeats

Brain.fm offers "functional music" for focus, relaxation and sleep as a subscription, and describes its music as designed with neuroscience research. ONDA takes a different approach: it composes calm ambient music live on your device so it never loops, makes no claims about effects on the brain, runs in the browser without an install and is free during its preview.

Two different philosophies

Brain.fm builds its product around the idea that specially designed music can affect attention, and presents research to support that. ONDA deliberately makes no such claim. It is a beautiful, unobtrusive sound environment for work, composed fresh as you listen; whether it helps you is something only you can judge.

What ONDA gives you for focus

Three Focus soundscapes: Quiet Momentum, Deep Work and Flow State.
Endless music with no track changes, so nothing interrupts a session.
An optional soft masking bed for noisy rooms.
A timer that fades out when your work block ends.
No account needed to start, no ads, no trackers.

Where Brain.fm may suit you better

If you specifically want music that is marketed with research on attention, or a large library of tracks in many genres, Brain.fm is designed for that.

Questions

Does ONDA claim to improve focus?

No. ONDA is calm, wordless music for working in. It makes no claim about effects on attention or the brain; everyone experiences sound differently.

Is ONDA free?

Yes, during the preview. You can listen for 10 minutes straight away with no sign-up, then create a free account with just an email address to keep listening.

Does the music loop?

No. ONDA chooses every chord and phrase as it plays, so an hour in it still has not repeated itself. There is no file to come to the end of.
