Awsome app. Wind is difficult to predict, but sailflow almost always gets it right or very close. We've been using it for surfing for years. Our plans revolve around the data on sailflow. Alerts taylored to SURFERS would be an excellent upgrade, and i would love to see the map predictions show hourly updates vs every 3 hours if that level of accuracy is possible. Still the best thing around. 👍

Been using this app for 10 years App always had an upgrade feature, but the app has ads so most weather stations were free to use for current condition and forecast. Now the greedy developers made the any feature an upgrade. All stations say experimental and can't see anything. Just used this app like a month ago.. used to have 4 stars now it's 1.

Randy, W H A T? We have not changed anything. Most of the stations are Free to use; you must have hit some option that changed what you were looking at. It's unclear. Anyhow- our Customer Support team can help you with whatever issue you are having! Give us a jingle at: App Main Menu > Settings & Help > Contact Us.
