iPhone
Real-time pure-sine binaural beats for focus, sleep, calm, and more. Sleep timer, lock-screen controls, and your own custom frequencies.
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.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
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.
