Advanced Binaural Brainwave Entrainment developed specifically for neuro athletic training. Features 8 Multi-Stage Binaural Programs developed from the ground up for athletes. This app is unlike any other brainwave entrainment application. Other brainwave and binaural beat applications use only a single brainwave frequency and carrier signal. The Progressive Brainwave Entrainment algorithms developed for this app use a series of brainwave stages, with multiple frequencies and carrier waves to gently bring your brainwave frequencies to your desired state using a more natural and effective frequency progression. *** Advanced Features *** - Multiple Brainwave programs each specially designed to boost physical and mental performance. - Multiple ambient background sounds to choose from. - Adjustable Brainwave Intensity - The intensity of the brainwaves can be adjusted independently of the ambient background sound. This allows you to set the brainwave volume to your comfort level. The application will also save your preference for future use. - Adjustable ambient background volume. - Visual timer countdown indicator. - Automatic saving of preferred brainwave entrainment program and ambient background sounds. - Ability to create your own custom time option. *** Included Programs *** - Quick Energy: Single-stage program targeting 30 Hz High-Beta/Low-Gamma for a quick energy boost. - Power and Focus: Multi-stage program targeting 6 Hz Theta, 20 Hz Beta, and 40 Hz Gamma to increase focus and intensity. - Fast Reflexes: Multi-stage program targeting high gamma frequencies to enhance reflexes and reaction time. - Eye/Hand Coordination: Multi-stage program focused on mid beta and high alpha frequencies to promote relaxed focused attention. - Endurance: Multi-stage Alpha, Beta, and Gamma program designed to increase your endurance and stamina. - Speed: Multi-stage program targeting very high gamma frequencies. - Rest and Recover: Multi-stage deep sleep program designed to enhance recovery after a workout. - Recovery Meditation: Multi-stage Alpha and Theta program designed to boost recovery and relaxation after a workout. ** How Binaural Brainwave Entrainment Works ** Through the process of brainwave entrainment human brainwave frequencies can be synchronized with a frequency associated with a target mental state. These Brainwave frequencies are too low for the human ear to hear, however, these low-frequencies can be perceived by the human brain if two different audible frequencies are played separately into each ear with headphones or earbuds. For example, the human ear can't directly perceive the 10 Hz Alpha frequency associated with relaxed alertness, but if you wear headphones with one side playing a 135 Hz tone and the other playing a 145 Hz tone, your brain will perceive the 10 Hz difference between those frequencies as a periodic beat. As you listen, your brainwaves will begin to match that frequency, inducing the associated mental state. Warning: Do not use this app while driving or operating machinery.

This is a straightforward app to help you achieve a chosen mind-state by generating what are known as "binaural beat audio waves" through your headphones, either from your iOS device or your Apple Watch. Depending on the frequency that you pick, based on the chart included in the app, it can potentially help with sleep, meditation, relaxation, or even for getting a short burst of energy. I have used similar apps for a while and have found them useful in helping me relax, or helping me float into a creative mood - Except most are overloaded with features that I never use and also cost money, have in-app purchases for "special programmes" and so on. So I decided to build one that does the same, works offline, has no ads or spying, works well, and is free. There's also an Apple Watch app included which you can use if you're mediating or relaxing away from your phone. As such, this app just generates the binaural frequency audio hum, and some optional white or brown noise to help mask outside sounds. You can then put it in the background and combine its audio with any other sound generator you like, or play music, radio, and so forth. All it does is to create the useful brainwave frequency, and then it gets out of your way.
