[Yojan]

Anemometer for Android - new app appeared today on Google Play:
https://play.google.com/store/apps/details?id=org.livelocalizer.anemometer
The application uses sound waves, created by wind flowing around the smartphone to derive the wind velocity.
Works from 0 to about 15 m/s!
A must for paragliders, kiters, sailors, etc.
