Aetherometer

Aetherometer puts three instruments for Earth's field in one app, ordered by scale. LEYLINE: In your hand Reads your phone's magnetometer and shows the local magnetic field in microtesla. Run a survey on foot and record it. Surveys can be exported as GPX. EARTHTUNE: Planet-wide Shows the Schumann resonance fundamental in hertz from the EarthTune observatory feed, and lets you listen to it. LIMEN: At the boundary Shows the magnetopause standoff distance in Earth radii. It is modeled from NOAA SWPC solar wind data using the Shue 1998 model, and the app labels it as modeled. THE BELT The home screen shows all three readings at once. Open an instrument and a bar lets you go back or jump straight to another one. A listening session keeps playing and a survey keeps recording while you look at a different instrument. HONEST BY DESIGN Each reading is marked as live, modeled, stale or sample, so…
