  • The rugged and electronic-free Vaavud wind meter turns your compatible smartphone into a high-tech meteorological tool, measuring wind speeds up to 48 knots with near-professional precision. Its unique design and electronic-free technology provide durability and reliability to meet the demands of an active life and the powerful Vaavud App provides an extremely easy to read and user-friendly interface, with the potential for expanded functionality and interaction.


    With its compact two cup design, inspired by professional anemometers, the Vaavud wind meter is accurate, practical and truly pocket friendly. It has a one piece durable plastic rotor and low friction PTFE bearing. Reliability and long service life are assured through the use of revolutionary electronic-free technology, communicating directly with the magnetic field sensor in your smartphone.

    Vaavud App

    The Vaavud App measures and displays wind speed in commonly used units of measurement. It has a neat and clean interface that shows the most important wind characteristics: actual, mean and max wind speeds. The smoothed graph provides additional data on variations in strength as well as a quick overview. The graph supports both drag and pinch to zoom so data can be viewed in fine detail.

    The Vaavud App is available free from the Apple App Store, Android Market and web sites. The Vaavud development team is working on adding History and Map features to the App, which will allow users to easily share wind information and help each other find the perfect location for every activity.


    The Vaavud wind meter has a wind range from 4 knots up to 48 knots (2 m/s up to 25 m/s). Accuracy is the lower of +- 4% and 0.4 knots (0.2 m/s), with testing and calibration confirmed in the professional wind tunnel at the Technical University of Denmark. The cup anemometer design makes the Vaavud less sensitive to the way it is pointed; a weakness in impeller type wind meters.

    Compatible with Smartphones and Tablets

    The Vaavud wind meter application works on iOS or Android smartphones. The electronic-free signal transfer utilises the magnetic field sensor, often called a digital compass, in your phone or tablet. To be able to detect high wind speed this sensor requires a high update/refresh frequency. The following devices have been confirmed as capable with the Vaavud wind meter and App, and will function across the full working wind range.

    Compatible With:

    • Apple iPhone 4 / 4s / 5
    • Apple iPad 2, 3 and 4th generation / mini
    • Samsung Galaxy S2 / S3 / S4
