THREE INSTRUMENTS FOR EARTH’S FIELD — ONE APP
Aether Toolbelt holds three instruments, ordered by scale. Leyline reads the magnetic field in your hand. EarthTune follows Earth’s measured Schumann tone. Limen watches the solar wind press on Earth’s magnetic boundary. The home screen shows all three readings at once, and every number arrives with its source and its age.
// THE BELT
Open any instrument from the belt. A bar above it takes you back or straight across to another one, and a listening session or a survey keeps running while you look elsewhere.
Reads this phone’s magnetometer in µT and shows the change from your survey site’s baseline. Walk a survey and it tags each sample to a trail on the map, then exports CSV or GPX. It reports the field, not ley lines or energy.
Follows the Schumann fundamental measured from public ELF observatory spectrograms, shown as Tomsk • 7.88 Hz • 12 min ago, and glides binaural or isochronic audio to match it. If the stations go quiet, it says so. Wellness tool, not a medical device.
Reads NOAA SWPC real-time solar-wind data and models where Earth’s magnetopause stands (Shue et al. 1998), with the age of every sample. Keep private field stamps of what you saw. An observation instrument, not a forecast.
One paid download, with every feature of all three instruments, including EarthTune’s Spectrum and 20- and 45-minute sessions and Limen’s 24-hour trace and stamp export. No in-app purchases, no subscription.
// PRIVATE BY DESIGN
EarthTune fetches its numbers from our anonymous, read-only feed, and Limen reads NOAA directly. Leyline’s location and magnetometer readings never leave the device unless you export them yourself. The privacy policy is the whole story.
