Tired of going out on your boat only to find yourself stuck in the middle of the sea due to a sudden dead calm, or worse, having to fight against dangerous gusts? SailDay is your ultimate digital tactician. The only weather app designed exclusively for those who go to sea. Instead of making you decipher dozens of complex weather charts, SailDay analyzes the data for you and gives you a clear score from 0 to 100 on the "Sailing Quality". Choose your Boat in your profile, and the algorithm will adapt to your needs: • Dinghy or Small Boat? The app will look for days with light wind and calm seas for safe and fun outings. • Cruiser or Racing? The app will focus entirely on steady, strong wind to get you planing with full sails. MAIN FEATURES: • Ruthless Algorithm: We analyze Knots, Gusts, Rain, and Thunderstorm Risk to tell you exactly when to cast off. • Smart Push Notifications: Add your favorite ports or bays, and we'll notify you when a "Perfect Wind" is on the way. • Gear Advice: Based on wind strength and temperature, we suggest the right outfit (e.g., ocean foul weather gear or light jacket) and sail trim (e.g., full sails or reefed). • Legendary Database: Over 100 of the world's most famous ports, marinas, and straits pre-loaded, from Porto Cervo to the Strait of Bonifacio, from Cowes to Antigua. And if your secret bay isn't there, you can search and add it! • Webcams & Maps: Access live webcams of the port with a single tap to check conditions in real-time. SAILDAY PREMIUM: Upgrade to Premium to unlock the app's full potential: • Extended 10-day forecasts (to plan your cruises or weekends in advance). • Unlimited ports saved on your Home screen. • Unlimited push notifications across all your routes. Stop wasting your weekends in port. Download SailDay, hoist the sails, and get ready for the perfect navigation. --- Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
