I turned a Russian observatory's raw data into a simple wellness score. Here's why I built it.

Earth has an electromagnetic pulse. It's real, it's measurable, and scientists have been tracking it since the 1950s. It's called the Schumann Resonance: a 7.83 Hz frequency that resonates in the cavity between Earth's surface and the ionosphere.

There's a monitoring station in Tomsk, Russia that has been recording it since the 1970s. Every hour, it publishes a spectrogram: a visual map of electromagnetic frequencies between 0 and 50 Hz. Fascinating data.

Almost unreadable unless you have a physics degree.

Most people who find this information encounter it through wellness communities, where it's either overhyped or fear-driven, like "know when you'll get sick," that kind of thing. I wanted to build something different.

So I wrote an algorithm that processes the Tomsk spectrogram every hour, extracts the relevant signal from the 7–8 Hz band, combines it with NOAA solar and geomagnetic data, and outputs a single number: an Activity Index from 0 to 100. Something you can check like the weather, with a plain-language explanation of what's happening.

No fear. No health claims. Just data, self-awareness, and tools to actually navigate the shifts: grounding techniques, breathwork, and other evidence-backed pactices instead of just bracing for them.

Just released the Android app two weeks ago. iOS coming soon.

Question for this community: Had you heard of the Schumann Resonance before? And if not, does the idea of tracking Earth's electromagnetic environment alongside your mood sound interesting, or does it feel too far out there?
