Aerial Cal Measures What Crop-Spraying Aircraft Actually Put on the Ground

Why it surfaced

Aerial Cal is unusually concrete: applicators photograph cards after a real pass, analyze them on the device without a signal, and receive a report they can save, print, or share. Its optional “Truth Test” compares two passes after changing one variable, turning spray calibration into an evidence trail rather than a guess.

A field-ready browser app that reads water-sensitive paper cards to measure spray coverage, droplet size, uniformity, drift risk, and effective swath spacing.
