The app you were missing for windsurfing. Discover spots and their weather forecasts, create and share your sessions with fellow windsurfers. Plus, you can also broadcast sessions in real-time. This means you can see data on speed, distance, and even the geolocation of the rider who has activated this option. For example, you'll know if your friend who just entered the water is planing or not. This will provide you with all the information you need to decide whether to hit the water or not. This also gives you an extra layer of safety at sea, as in sessions with some risk, you can alert the community to your situation and location in real time (we do not recommend taking risks under any circumstances and you should bear in mind that this option depends entirely on your phone's connection and battery, so it is not infallible, just an additional safety feature). Another important part of the app is the discovery of spots. The app has a global list of spots, dynamically growing, because users can add their favorite spots. Get to know all the detailed info of the spot written by a local and the weather forecasts from the best wind models. Just like the spots, registered users also generate data related to their activity and thanks to this, from the user account, you can access the sessions enjoyed and all the statistical data obtained as a result. For example, you can see what size sails you have used most often or the wind conditions on a specific past day. Also, which spots you have visited the most, what are your usual conditions... There are endless possibilities. In short, an app that we hope will make windsurfers have fun and gain information and safety in the water. *** The weather models data are obtained thanks to the API from Open-meteo.com, which supports us by allowing PRO access to their API. *** Note: Real-time GPS location use requires an internet connection and GPS operation in the background (with the screen off). This entails battery consumption. Therefore, we recommend that you consider your battery level when you start a session.
