Entrain: Binaural & Isochronic

Quiet your mind or sharpen your focus — with sound generated live on your device. Free to start, no account, no sign-up. Entrain creates neural entrainment audio two ways, so you're never tied to your headphones: • BINAURAL BEATS — a slightly different tone in each ear creates a phantom beat your brain follows. Best with headphones. • ISOCHRONIC TONES — a single pulsing tone that works on any speaker, Bluetooth, AirPlay or in the car. No headphones required. Pick a goal and Entrain tunes itself to the right brainwave band: • Delta — deep, dreamless sleep • Theta — meditation and calm • Alpha — relaxed focus and flow • Beta — alert, active focus • Gamma — peak concentration FREE — no account needed • Both engines: binaural beats and isochronic tones • All five brainwave bands, fully adjustable • A warm brown-noise layer • Sessions up to 30 minutes ENTRAIN PRO • Unlimited, all-night sessions • Background and lock-screen playback • Presets for Sleep, Relax, Focus and Energy — plus save your own • Mix brown, pink, rain and ocean ambience • Sleep timer with a gentle fade-out, up to 8 hours • Apple Watch app — listen from your wrist with AirPods, no iPhone • Also runs on Mac • Live waveform, session history and a daily streak BUILT TO JUST WORK • Plays fully offline — nothing streams • Lightweight, private and battery-friendly PRICING Try everything free for 7 days. Then Entrain Pro is $4.99/month or $44.99/year — about half what other binaural apps charge. Cancel anytime, or keep using the free version as long as you like. A note on the science: neural entrainment is widely enjoyed for relaxation, focus and sleep, but it is not a medical treatment. If you have a seizure disorder, talk to a doctor before use.
