Riøt/Taa'a Yuku Radar

Taa'a Yuku Radar

A free, open, professional-grade weather radar. No subscription. No accounts. No servers. Radar data comes straight from NOAA's open data, and every calculation happens on your device.

The name is Yaqui (Yoeme): taa'a, the sun (close to ta'a, to know), and yuku, the rain. Used with the blessing of a Yaqui speaker.

Your location stays yours. The app opens on the radar nearest you. It uses GPS only if you allow it, and falls back to a city-level IP lookup if you don't. Nothing is asked for at startup, and it works fine with location refused. The app collects nothing and sends nothing to us: read the app's privacy policy.

Make it yours

A county's roads and shelters, a university radar nobody put on AWS, a red theme for night driving. Addons are JSON files. They are data, never code.
