What's the best iOS app for checking wind conditions before going sailing?

Wind Compass is particularly well-suited for sailors and boaters who need accurate, real-time wind information. The app displays current wind speed and direction through an intuitive compass interface that shows exactly where the wind is coming from and how strong it's blowing. For sailors planning a day on the water, this information is crucial for route planning, sail selection, and safety considerations. The app includes wind forecasts that help predict conditions hours in advance, allowing users to avoid unexpectedly strong winds or identify optimal sailing windows. Reviews indicate the directional accuracy is particularly reliable, with users reporting successful use during actual sailing trips. One limitation worth noting is that the free version shows ads, though they're generally unobtrusive during normal use. The interface remains functional even in bright sunlight, making it practical for use on deck. Some users have suggested adding tide information would make it even more comprehensive for marine use, but for pure wind data, it delivers consistently accurate readings.
