Why a lo-fi radio extension instead of a tab?

Because YouTube is a feed. Spotify wants you logged in. A focus radio shouldn't ask for either.

01
Survives a closed tab

Audio runs from the extension itself, not a browser tab. Close every tab — the music keeps playing.
02
One toolbar click

No reach for the dock. No context switch. Tonearm lives one pixel away from where you're already working.
03
Vinyl-warm interface

FAQ.

Is Tonearm really free?

Yes. No premium tier, no trial, no in-app purchases. The streams are public radio feeds; we curate and present them.

Do you collect data on what I listen to?

No. There's no account, no analytics tied to you, and nothing about your listening history leaves your browser. The only network traffic is the audio stream from the station you chose.

What's lo-fi music, and why use it for focus?

Lo-fi is instrumental hip-hop and downtempo electronica with a soft, lived-in sound — vinyl crackle, muted drums, melodic samples. It's lyric-light and rhythm-steady, which makes it less likely to compete with the language part of your brain while you work. We have a deeper take on the same idea on our focus music browser extension and music for coding pages.

Will the music keep playing if I close the popup?

Yes. Audio runs from the extension's background, not the popup window. Close the popup, switch tabs, even close every tab — the stream continues until you stop it.

Does it work on Firefox / Edge / Safari?

Chrome only at launch. Firefox and Edge are likely v2; Safari needs more research.

What about Mac?

A native menu-bar app for macOS is in development — see the Tonearm for Mac page.
