The Schumann resonances (SR) are a set of spectrum peaks in the extremely low frequency (ELF) portion of the Earth’s electromagnetic field spectrum. Schumann resonances are global electromagnetic resonances, generated and excited by lightning discharges in the cavity formed by the Earth’s surface and the ionosphere.
Why Put Them in an App? The Schumann resonances are tied to an elevation in human consciousness. When there are spikes in activity people have noticed a change in behavior. The apps have been created in order to allow for people to easily check the status of the Schumann on their phones. This is just an easy-check of where the levels are.
