Stimulation of the brain through exposure to visual and auditory receptors from one of the typical brain frequencies (Alpha, Beta, ...). Along with the preset frequencies (Alpha and Beta), it is possible to indicate your own. There is a schedule of stimulations. There is a counter and a stimulation limit per day. There is an automatic launch of the application when the device is restarted. Thanks to all of the above - the application does not require your attention after installation and one-time setup.
