Endel and Liminal both make sound for focus, relaxation and sleep. Endel generates soundscapes that adapt to you automatically, so you barely have to touch it. Liminal is an instrument you can tune, built around binaural beats and isochronic tones. Here's how they compare, including where Endel is the better choice.
At a glance
| Liminal | Endel | |
|---|---|---|
| Approach | A tunable instrument: binaural beats, isochronic tones and Solfeggio frequencies over layered soundscapes | Generative soundscapes that adapt in real time |
| What you control | Carrier and beat frequency, named brainwave bands, layers, 5-band EQ (Pro), multi-phase session designer (Pro) | Mode and timer; the sound adapts on its own |
| Adapts to | Your choices and the session you design | Time of day, weather, heart rate, location and movement |
| Binaural beats | Yes, at the core, plus isochronic tones that work without headphones | One Binaural Beats scenario |
| Use cases | Sleep, focus, calm, meditation and lucid dreaming practice | Focus, relax, sleep and activity |
| Science | Explains the mechanism and says plainly that the evidence is mixed | Cites its own whitepaper and user surveys, and says it may not work for everyone |
| Free option | Free forever, no credit card | Paid subscription (see endel.io for current plans) |
| Platforms | Web app | iOS, Android, Apple Watch, Mac, web, Alexa and TV |
How each one works
Endel generates sound continuously and shapes it using signals such as the time of day, the weather, your heart rate and your location, along with your circadian rhythm. You pick a mode, such as Focus, Relax, Sleep or Activity, or let Autoplay choose, and press start.
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. Our guide to binaural beats and isochronic tones explains the difference between the two.
Where Endel is the better choice
- You want zero setup. Endel adapts by itself; there's nothing to tune.

- You want a widely used app. Endel reports over 4 million downloads and won Apple Watch App of the Year in 2020.
Where Liminal is the better choice
- You want control. Choose the exact frequency, stack layers, EQ the sound and design multi-phase sessions.
- You want to explore entrainment. Binaural beats, isochronic tones and Solfeggio are Liminal's core, not a single scenario.
- You practise meditation or lucid dreaming. Liminal has sessions and a seven-day program for these.
- You want a real free tier. Liminal's free tier doesn't expire and needs no credit card.
- You want honesty about the science. We tell you the evidence for binaural beats is mixed, and our claims don't rest on our own surveys.
