Not real
Binaural beats should sound like a steady tone in each individual ear. The tones should be slightly different. Your brain then combines them to create a beating sound in your brain. This app has a beat in each ear. That doesnt work.
Try Brain Wave. Brain Wave appears to be real. I have tried the Brin Wave Lucid Dreaming track and have had awesome dreams for the last several days, after using it once.
