Z-App is a frequency generator app built on the technology of Royal Raymond Rife. The common devices are better known as Rife Frequency Generators. These generators use frequencies to break down the protective walls of pathogens much like a high music note breaks a crystal glass. This app includes more than 1300 sequences and 1400 frequencies. This app along with a device we designed and manufacture called Z-Amplifier (for more information visit http://www.zappkit.com) make a complete frequency machine. The Z-App generates and plays the sequences and frequencies and the Z-Amplifier connects to your phone or tablet and converts the audio frequencies to electrical frequencies that can be applied using electrode patches metal cylinders foot patches or crystal cylinders.
