## What is Binaural Beats?

Binaural Beats plays two pure sine tones at slightly different frequencies — one in each ear — so your brain perceives the difference as a gentle beat that guides your brainwaves.

Unlike apps that loop pre-recorded audio, every tone is synthesized in real time for a clean, precise binaural signal, layered with a soft ambient pad.

WHO IT'S FOR
• Studying or deep work — Beta (16 Hz)
• Meditation — Theta (6 Hz)
• Stress relief — Alpha (10 Hz)
• Falling asleep — Delta (2 Hz)
• Workouts — Gamma (30 Hz)
• Creative flow — Alpha-Theta (7.5 Hz)

FEATURES
• 6 purpose-built brainwave modes
• Custom session — set your own carrier and beat frequency
• Sleep timer with gentle fade-out
• Background playback with lock-screen controls
• English and Korean

IMPORTANT
• Headphones or earphones are required — the effect does not work through a speaker.
• For relaxation and focus support only. Not a medical device or a substitute for medical advice.

## Version history (last 2 releases)

### 1.0.1 — 2026-07-22

Drift off and dial in with four new ways to listen:

• Journeys — the frequency now glides over time. Ease into sleep as it descends from Alpha to Delta, or wake up gently as it rises from Theta to Beta.
• Solfeggio frequencies — six classic tones (396–852 Hz), each paired with a 7.83 Hz Schumann-resonance beat.
• Ambient sound mixer — layer rain, waves, wind, or white noise under any session, each with its own volume.
• Live Activity & Dynamic Island — see your current mode, elapsed time, and sleep-timer countdown right on the Lock Screen.

Plus more reliable banner loading and behind-the-scenes fixes.

### 1.0 — 2026-06-10
