Windsurf Diary helps you record, rate and search your windsurfing sessions.
Use the app after a windsurfing session to record: the wind conditions, the sail and board you used, and a 'rating' measure of how well the sail/board combination suited the conditions.
After you have recorded a sufficient number of sessions you can use the app before rigging-up to search your historic sessions to find the best sail and board for the current wind conditions.
