Windy is a revolutionary tool for weather visualization. This fast, easy to use and most accurate weather app is trusted by professionals from many fields who rely heavily on accurate and up to date weather information.

Pilots, paragliders, skydivers, kiters, surfers, boaters, fishermen, storm chasers, and many others use it to check weather conditions in their area of operation.

Whether you are planning a hike, tracking a tropical storm, pursuing your favourite outdoor sport or you just need to know if it will rain this weekend, Windy provides you with the most up-to-date weather forecast around.

Windy has the ability to provide much more accurate information than any other weather app. Moreover, it is absolutely free and without ads. It's also lightweight and doesn't require much space. In my opinion, it's a must-have.
