The free binaural beats app for sleep, focus & meditation
The Dream Machine is a completely free binaural beats and isochronic tones app built for real results — deeper sleep, sharper focus, calmer meditation, and everyday relaxation. Everything is unlocked, there are no ads, and there's nothing to subscribe to. Here's everything you need to know.
What are binaural beats?
Binaural beats are a form of brainwave entrainment. When you play two slightly different frequencies — one in your left ear and one in your right — your brain perceives a third, phantom "beat" equal to the difference between them. That perceived beat can gently encourage your brainwaves toward a target state, which is why so many people reach for binaural beats for sleep, studying, focus, meditation, and winding down after a stressful day. For the effect to work you'll want stereo headphones, so each ear receives its own tone.
Binaural beats vs. isochronic tones
The Dream Machine gives you both. Binaural beats use two tones and need headphones. Isochronic tones are single, evenly-spaced pulses of sound that switch on and off rapidly — many people find them even stronger, and they work through headphones or speakers. You can layer either one with ambient soundscapes to build your own custom audio environment. Learn more on our binaural beats guide and browse the scientific studies.
Free binaural beats for sleep
Struggling to fall asleep? The app includes dedicated sleep programs and layered "sleep beds" tuned to slow delta waves (1–4 Hz), the frequency range associated with deep, restorative rest. Combine them with ocean waves, gentle rain, distant thunder, a crackling fire, or brown noise to mask distractions and drift off faster — completely free, for as long as you like.
Binaural beats for focus & studying
Need to lock in? Reach for beta (13–30 Hz) for active concentration or alpha (8–13 Hz) for relaxed, flow-state focus. Students use binaural beats and isochronic tones as focus music for studying, deep work, reading, and coding sessions. Clean carrier tones and adjustable intensity let you dial in exactly what keeps you in the zone.
Binaural beats for meditation & relaxation
Theta waves (4–8 Hz) are linked to meditation, creativity, and deep relaxation, making them a favorite for mindfulness, breathwork, and calming anxiety at the end of the day. The Dream Machine lets you settle into a stable meditative state without years of practice — just put on headphones, choose a program, and breathe.

Why it's free (and how it stays that way)
We believe tools that help people rest and focus should be available to everyone, so The Dream Machine is free forever with no ads and no subscription. If the app genuinely helps you, you can choose to leave the developer a small, optional tip right inside the app — that's the only way it earns anything, and it's completely voluntary. Download it free on Google Play today; the iPhone version is coming soon.
