Entrain: Binaural Beats

Calm focus & deep sleep tones

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Entrain is brainwave entrainment for people who actually use it — built to be precise and potent, not another spa-music app. Play two slightly different tones, one in each ear, and your brain perceives the difference as a “beat.” The frequency-following response gently nudges your brainwaves toward it — toward deep delta for sleep, theta for meditation, alpha for calm focus, or beta for alert work. WHAT MAKES ENTRAIN DIFFERENT • Three modes — binaural (headphones), isochronic (works on a speaker), and monaural • Set the exact frequencies — carrier and beat Hz, not vague “sleep/focus” buttons • Descent programs — glide the beat from alert down into deep sleep over a session • Synthesized sound beds — brown, pink, and white noise, mixable under the tone • True L/R balance for hearing asymmetry • Sleep timer with a gentle fade, background playback, lock-screen controls • Works fully offline, no account — the audio is generated on your device PRESETS FOR EVERY STATE Deep Sleep · Power Nap · Theta Meditation · Schumann 7.83 · Locked-In Focus · Flow · Gamma Insight · Calm · Lucid Threshold · 528 Hz · 432 Hz, and more. For best results with binaural beats, use headphones. Entrain is designed for relaxation, focus, and meditation support.

Thanks for using Entrain. This update brings small refinements and polish under the hood. If it's helping you sleep, focus, or unwind, a quick rating means a lot to an independent app like this one.
