Zephyrus works as an anemometer, just using your smartphone microphone! This free edition has a reduced size ideal for basic cell phones.

If you have a powerful phone model, try our last Zephyrus Lite edition (free)!

Dynamic wind speed measuring mode with real time chart, wind direction display and calibration.

The typical wind range is 1-16 m/s (max 20 m/s): the full scale is limited by the internal mic maximum SPL.
