The binaural effect only works over stereo headphones or earbuds — it depends on each ear hearing a slightly different tone, which a phone speaker can't reproduce. Without headphones you'll still hear the ambient piano/flute/nature layer, just not the binaural tone itself.

This can happen on some phones/browsers despite our background-audio safeguards. Try: keeping "Low Power Mode" off during a session, allowing the App's notification permission (Settings → Sessions → enable end-of-session notification), or using the "Keep screen on instead" option under Session Options if background audio is unreliable on your specific device.

See our Terms of Service for the current refund policy, or just email us — we'd rather sort it out directly.

Please include your device, browser, and what preset/settings you were using — it makes it much faster for us to reproduce and fix.
