Help & FAQ
What are binaural beats?
A binaural beat is the rhythm your brain perceives when each ear hears a slightly different tone. A 200 Hz tone in one ear and 210 Hz in the other is heard as a 10 Hz pulse, which sits in the alpha range linked with relaxed awareness.
Is MindSync free?
Yes. MindSync is free, has no ads and does not need an account.
Which devices does MindSync support?
MindSync is built for iPhone and Android phones. Download links will appear on this page at launch.
Why do I need headphones?
Binaural beats rely on each ear hearing its own tone. Speakers still work, but the effect is subtler.
How long should I listen?
Start with 15–30 minutes. Use the timer, or leave it on infinite for sleep.
Does it play in the background?
Yes. Audio continues with the screen locked, and you can pause from the lock screen.
Is it a medical treatment?
No. MindSync is for relaxation and focus and is not a medical device.
