Liminal and Brain.fm both use sound to help you focus, relax or sleep, but they take opposite approaches. Brain.fm gives you finished music engineered by its own team; you pick an activity and press play. Liminal gives you an instrument: you choose the frequencies, the layers and the shape of the session, or start from a preset. Here's how they compare, including where Brain.fm is the better choice.
At a glance
| Liminal | Brain.fm | |
|---|---|---|
| Approach | A tunable instrument: binaural beats, isochronic tones and Solfeggio frequencies over layered soundscapes | Functional music with patented modulation, picked by activity |
| What you control | Carrier and beat frequency, named brainwave bands, layers, 5-band EQ (Pro), multi-phase session designer (Pro) | Activity mode (for example Deep Work, Deep Sleep, Unwind) |
| Binaural beats | Yes, at the core, plus isochronic tones that work without headphones | No. Brain.fm says its method is not binaural beats |
| Use cases | Sleep, focus, calm, meditation and lucid dreaming practice | Focus, relax, sleep and meditate, with music designed for ADHD |
| Science | Explains the mechanism and says plainly that the evidence is mixed | Peer-reviewed studies by its own science team, and National Science Foundation support |
| Free option | Free forever, no credit card | Free trial, then paid |
| Paid price | $5.99/month or $39.99/year | $14.99/month or $99.99/year |
| Platforms | Web app | Web, iOS, Android and desktop |
How each one works
Brain.fm describes its technology as patented neural entrainment: modulation built into the music within each stereo channel, which it says produces stronger neural phase locking than binaural beats. You choose an activity, such as Deep Work, Creativity, Power Nap or Deep Sleep, and Brain.fm plays music designed for it.
Liminal works with the classic tools of brainwave entrainment. Send a slightly different tone to each ear and your brain perceives a beat at the difference: 200 Hz and 210 Hz becomes a 10 Hz Alpha rhythm. You can set that carrier and beat by ear, jump to a named band from Delta to Gamma, add isochronic pulses or Solfeggio tones, and layer rain, forest or drones underneath.

Where Brain.fm is the better choice
- You want music, not tones. Brain.fm sounds like a produced track. Liminal's core sound is tones and soundscapes.
- You want published research behind the product itself. Brain.fm's team has published studies on its own music and is supported by the National Science Foundation.
- ADHD is your main reason. Brain.fm designs and studies music specifically for attention difficulties. Liminal makes no ADHD claims.
- You want native apps everywhere today. Brain.fm runs on web, iOS, Android and desktop.
Where Liminal is the better choice
- You want to know exactly what you're hearing. Every Liminal session shows its frequencies, and you can change them.
- You're curious about binaural beats, isochronic tones or Solfeggio. These are Liminal's foundation; Brain.fm deliberately avoids them.
- You practise meditation or lucid dreaming. Liminal has sessions and a seven-day program built for these, not just focus and sleep.
- You want a real free tier. Liminal's free tier doesn't expire, and Pro costs less than half of Brain.fm per month.
- You want honesty about the science. We tell you the evidence for binaural beats is mixed, and that effects are modest and vary from person to person.
Pricing
Liminal is free forever for preset sessions across every band, simple tone control with one soundscape, and the journal. Pro, at $5.99 a month or $39.99 a year, unlocks the full instrument. Brain.fm offers a free trial, then $14.99 a month or $99.99 a year. Prices are as listed on each website on October 29, 2026.
The short version
Pick Brain.fm if you want polished focus music that just works, backed by its own research, especially for ADHD. Pick Liminal if you want to tune the frequencies yourself, explore binaural beats, isochronic tones and Solfeggio, or practise meditation and lucid dreaming, with a free tier to try it first.
FAQ
Is Brain.fm the same as binaural beats?
No. Brain.fm says its music uses a patented modulation method inside each stereo channel and is not binaural beats. Liminal is built around binaural beats and isochronic tones you can tune directly.
Which is cheaper, Liminal or Brain.fm?
Liminal has a free tier with no time limit, and Pro costs $5.99 a month or $39.99 a year. Brain.fm lists $14.99 a month or $99.99 a year after a free trial.
Which is better for ADHD?
Brain.fm has music designed and studied specifically for listeners with attention difficulties. Liminal makes no ADHD claims. If ADHD support is your main goal, Brain.fm has more research behind that use.
