## What is Entrain?

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. It is not a medical device and is not intended to diagnose, treat, cure, or prevent any condition.
