This APP is useful for personal and private meditation. It is designed as a personal lab for your own experimentation and relaxation. Read the built-in Guide for details. Pure sinusoidal tones of a selected frequency are produced in each ear. The left and right ear tones have individual frequencies where the difference is in the Alpha brain frequency range (8 to 12 Hz). For best results you should use headphones or earbuds to ensure that each ear only hears the single tone for that ear. Although these pure tones are unique to each ear, your brain will detect the frequency difference and will create a beat frequency in the Alpha range which you will sense. Your brain will respond to this Alpha beat frequency and will start to generate a matching Alpha signal through entrainment. Learning to achieve the Alpha state of consciousness will relax you and help to put you in a more relaxed and creative state of mind. This state of mind is normally reached during prolonged meditation. Relax, be patient and experiment with different frequencies and Alpha values to find the right tones that relax you. For a broader featured tool, check out the Alpha Pro app at the App Store. Alpha Pro covers the Delta, Theta, Alpha, Beta and Gamma brain frequencies with much more precise and finer control of frequencies at a much higher resolution. This provides a broader spectrum of opportunities for your own experiments. For more features and finer control check out the ALPHA PRO version on the App Store.
