Hook Echo

Hook Echo shows NEXRAD weather radar at full resolution, drawn on the GPU so it stays smooth on a laptop in a car. It opens straight to useful radar with no account and no setup.

- Every Level II product: reflectivity, velocity, spectrum width, differential reflectivity, correlation coefficient and differential phase, at every tilt
- A clean, map-first layout with floating glass panels, in dark and light themes
- Hover anywhere for the value, beam height, and range and bearing from the radar

Radar data comes from NOAA's free public feeds. Hook Echo has no telemetry and no accounts. It is free software (GPL-3.0-or-later); sources and licenses are at https://github.com/kz6fittycent/HookEcho.
