Feel the Wind: The Ultimate Sailing Companion WindTalker turns your Apple Watch and iPhone into a real-time sailing instrument β€” showing you exactly where the wind is coming from, how fast you're going, and where to point your bow next. TRUE WIND & APPARENT WIND See both the true wind (straight from Apple Weather) and the apparent wind you actually feel on deck β€” calculated live from your boat's speed and heading. Point your compass at the horizon and watch both arrows update in real time. OPTIMAL SAIL ANGLE Based on true wind, apparent wind, and your current point of sail β€” close-hauled, beam reach, broad reach, or downwind β€” WindTalker recommends the sail angle to get the most out of every gust. RACE START COUNTDOWN Cycle through 5, 3, or 1-minute countdowns (or an instant "Go"), with a reaction-delay setting that fires the start signal early so you're moving exactly on time. Voice, beep, and haptic cues keep you counted down without ever looking away from the line. COURSE MARK TRACKING Lay out your waypoints on iPhone and they sync straight to your watch. Live bearing and distance to your next mark, automatic advancement as you round each one β€” no more guessing where the next buoy is. BOUNDARY ALERTS Draw a sailing area and get an instant alert β€” with a live return bearing β€” the moment you drift outside it. Stay safe without staring at a map the whole time. VOYAGE LOG Every session's route, distance, speed, and calories are recorded to Apple Health, so you can relive (and improve on) every sail. Built for Apple Watch, and just as capable solo on iPhone β€” WindTalker is the sailing companion that reads the wind so you can glide the water.
