MindSync: Binaural Beats

MindSync plays a slightly different tone in each ear so your brain hears a third rhythm. Pick Focus, Relax, Meditate or Sleep, add rain or ocean, and press play. Free, with no ads and no account.

FEATURES

• Tuned presets or your own: Four ready-made modes, plus a Custom mode where you set the left and right frequencies yourself.
• Session routines: Chain states into one hands-free session such as Focus → Relax, Deep Work or Wind Down, or build and save your own.
• Layered ambience: Mix in soft noise, deep noise, rain or ocean, generated on your device, with a sound tone control from low to high.
• Sleep ramp: Slowly lowers the beat toward deep sleep and dims the screen while you drift off.
• Background and lock screen: Audio keeps playing with the screen locked, fades in and out smoothly, and can be paused from the lock screen.
• Journey and streaks: See today, the last 7 days and all-time listening, plus your day streak. Favourites and a Continue card get you back fast.
• Live wave visuals: Watch the left ear, right ear and perceived waves on an oscilloscope. Slow the animation if you are motion-sensitive.
• 10 languages: English, Arabic, German, Spanish, French, Italian, Japanese, Korean, Portuguese and Chinese, with full right-to-left support.
• Private by design: No account, no ads, no trackers. Your favourites, sessions and history stay on your device.

MODES

• Focus (Beta, 18 Hz): Alert, concentrated, active thinking. Ideal for deep work and study.
• Relax (Alpha, 10 Hz): Calm awareness and stress relief. Unwind between tasks or after work.
• Meditate (Theta, 6 Hz): Deep relaxation, creativity and meditation. Settle in and let go.
• Sleep (Delta, 3 Hz): A slow, deep rhythm for winding down and falling asleep.

MindSync is for relaxation and focus. It is not a medical device. Research on binaural beats is mixed, and MindSync makes no medical claims.
