"Inherit the speed of the wind"

Reviewed by / Jul 11, 2012

Use the app to know the wind velocity and learn if you can do your favorite activities

Anemometer is an application for Android devices which analyzes the spectrum of sound and uses that to measure the wind velocity, having previously filtered out the human voice or other sounds around.

That information can be really useful if you're looking forward to doing outdoor activities which might be cancelled because of the wind: fly a kite, sail and other several ones. When you first start the app, you should set the zero wind level and then you will get a graph in which you can see the meters per second and the peak depending on where you are. Of course, it's also pretty interesting to amateur meteorologists and related hobbies.

Undoubtedly, this is a useful application in general, it works well and we're satisfied with the results. Only one thing, the design does the work but it could be a bit prettier but, in general, we recommend Anemometer for all people who have been some time dissappointed when they couldn't do their favorite activity because of the wind. Igor Kreslo is the developer of Anemometer and other science-related apps. They state that this is not a scientific instrument and that the accuracy depends on the device and other factors, so of course it won't replace a professional anemometer, but it's a useful app and weighs less than a Mb., perfect to have it installed awaiting for the moment to be used or serve as a curiosity. In short, a smart use of what a smartphone can do.

Developer's original description available here
Anemometer is an application, that measures wind velocity
by analyzing spectrum of sound, created by the air flow around your Android device. It is a wind speed meter in your pocket.
The app is useful for people, doing outdoor activities depending on the wind,
such as paragliding, kite surfing or sailing.
This wind speed meter uses quite sophisticated algorithm to extract wind speed range from zero up to about 15m/s, depending
on the device. This algorithm allows to filter out most of sounds, so that human voice, or
noise of trees on the wind do not affect measurement accuracy.
Before starting to use anemometer please set zero wind level: hold your device in silent no-wind conditions
and press "Set zero" item in menu. The value will be stored in persistent memory, so you don't need to
do it often. However, if you feel that zero level is wrong for some reason - just re-do it.

New method of anemometer calibration is added:
put phone side by side with the reference anemometer instrument to a constant air flow, click on Menu-Calibration Point and enter wind speed, measured
by reference device. Calibration constant will be re-calculated automatically.

When the anemometer is stopped measured data is saved to file (10 points per second). Directory Anemometer is created when you launch application for the first time.
Data files are located in this directory, names start from W and contain date and time of saving.
Saving data can be also forced during measurement by swiping the screen.

The linearity and calibration of wind speed meter are ensured for Samsung Galaxy S, other devices
may show deviations from linear response. Use with caution!

The application is created on the basis of Hermit libraries by MoonBlink (http://code.google.com/p/moonblink/).

This program Anemometer is distributed WITHOUT ANY WARRANTY!

Recently changed in this version

10.07.2012 New method of anemometer calibration is added:
put phone side by side with the reference anemometer instrument to a constant air flow, click on Menu-Calibration Point and enter wind speed, measured
by reference device. Calibration constant will be re-calculated automatically.

25.07.2012 Widget is added! Now you can place a widget to your home screen. The Widget shows results of the last measurements. Clicking on widget starts the Anemometer.
