WindApp is a practical mobile app for wind energy enthusiasts and professionals that can estimate your energy and monetary savings for a specific wind turbine based on your local wind resource. Features such as built in mapping with your GPS location and the ability to add a customized wind PDF gives users the ability to account for local terrain and wind distributions. Manufacturers and installers can have their information updated at anytime and these updates are automatically uploaded to all the app users, without the need to for the user to update the app itself.
