SailingWatch vs Upwind

SailingWatch is the race companion for sailors — a precise start sequence, a real start line, live tactics, and your whole session on a map. Built for dinghies, keelboats and yachts, on iPhone and Apple Watch. THE START, NAILED EVERY TIME • A big, readable countdown with a sweep ring that drains as the gun approaches. • Sync to the committee boat in one tap, or fine-tune with −1 / +1 minute. • The final minute turns red so you always know how long you have. • Start, pause and resume right from the cockpit. A REAL START LINE • Ping the pin and the committee-boat ends to set the line. • See the line bias and your live distance to the line. • Time your approach instead of guessing. LIVE TACTICS • Capture your port and starboard tack angles. • A compass and layline call tell you if you're lifted, headed, or on the groove. • Make the smart call on when to tack. WIND AT A GLANCE • A 6-hour wind forecast strip for your exact location — speed, direction and gusts. • Know what's coming before you leave the dock. EVERY SESSION, ON A MAP • Automatic GPS recording while you sail — speed, heading and full track. • Review past sessions grouped by month. • Replay any track on the map with distance, duration and top speed. SHARE YOUR SAIL • Export a standard GPX file. • Create a video animation of your track to share. • Send your sessions straight to Strava. ON YOUR WRIST • The Apple Watch app puts the timer, start line and live data on your wrist — sail with your phone in your pocket. MADE YOURS • Save your boat profile — class, sail number, polar and hull length. • Choose your units for distance, speed and temperature. • A clean, high-contrast black-and-blue design that stays readable in bright sun. Whether you're lining up for the gun on a club Wednesday or training for the season, SailingWatch keeps the start, the line and the tactics one glance away. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
