This application brings the functionalities of an Anemometer (Wind Speed Meter) and of a Wind Spectrum Analyzer to your phone.No sensors required: realtime wind speed reading just using your smartphone microphone.The typical wind range is 1-16 m/s (max 20 m/s): the full scale is limited by the internal mic maximum SPL.
Unique features, multilingual, cross-platform, frequent updates: do you want more? simply ask!

>>Quick startThe application relies on the mobile microphone signal. To achieve the best results consider the following:1) Easy calibration (only the first time): for details see the calibration section of the user guide2) avoid measurement in presence of loud noises (heavy traffic, motorbikes, trucks, loud talking, shots)3) keep your fingers away from the mobile microphone (hold it by the top) and keep it in vertical position4) orient the back of the phone in the direction of the wind (keeping the display in front of you)5) click on one of the function buttons
This application is not meant to be used in place of scientific instrumentation, but with a good calibration it can come close to a real anemometer device.
