Music Made for Deep Work.
The only music app designed to get you locked-in.
One payment, not a subscription
Brain.fm is about $70 a year. Endel is about $50 a year. Tomatoes is $39 once, and that is it.
Built on real neuroscience
40 Hz gamma modulation. Nine sound layers running at once. Proper audio engineering, not mood music with a wellness label.
Lives in your menu bar
No app to switch to. No tab to find. The timer and the focus sound, both one click away.
No accounts. No internet.
Your Mac does all the work. No sign-up, no tracking, no data collection. Once it is installed, you can be offline forever.
Spotify is the wrong tool for focus.
Regular music is made to grab your attention. Hooks, builds, drops, vocals. Producers get paid to stop you drifting.
- Lyrics and hooks compete with your work
- Designed for entertainment, not deep work
- 47 minutes to reach focus, longer than a Pomodoro block
- Optimised to keep you listening, not working
Great for a run. Not for work.
One frequency. Your brain locks on.
It is called 40 Hz gamma. Play it, your brain tunes in. EEG studies have shown this for forty years.
Two recent peer-reviewed studies, one in Nature in 2020[1] and one in Current Psychology in 2023[2], both found that 40 Hz stimulation measurably improves sustained attention.
Focus score by frequency band
Aggregated across studies. 40 Hz gamma is the clear winner.

Tomatoes builds your focus sound live on your Mac. No playlists, no tracks, nothing to skip.
It never repeats. So you never break out of focus.
All of it pulses gently at 40 Hz
Quiet enough that you do not hear it. Consistent enough that your brain follows. (Technique validated in Nature Communications Biology, 2023.)
Listen for 30 seconds
This is what a focus session sounds like.
Headphones recommended. The 40 Hz pulse is subtle. The warm bed underneath is not.

40Hz gamma + noise, drone, pad, reverb
Headphones recommended for binaural effect
FAQs
Does this actually work?
For most people, yes, and modestly. 40 Hz gamma has real peer-reviewed research behind it (Nature 2020, Current Psychology 2023). The gains are measurable but not magic. We layer it into music you can actually listen to for three hours.
How is this different from Brain.fm or Endel?
Price, mostly. Brain.fm is about $70 a year. Endel is about $50 a year. Tomatoes is $39, once. Feature-wise, Tomatoes runs in your menu bar, includes a Pomodoro timer, and works offline.
What if it doesn't work for me?

Why macOS only?
Tomatoes is a menu bar app, which is a macOS thing. A Windows version is on the roadmap but not shipped yet.
