SailWatcher vs Current Coach

SailWatcher is the perfect app for all sailing and boating lovers. Whether you are an expert or a beginner enthusiast, this app will help you plan, monitor and live your adventures at sea to the fullest. Key features: - Track course and key points: While sailing, SailWatcher records the boat's GPS position and that of the points where the shots were taken to retrieve parameters - Practical and fast: To perform the analysis, simply take a shot, select the areas of interest and finally the LUFF. - Share: Once the parameters are calculated, you can share all the information, including the photo and personal notes, by generating a unique URL. - SailWatcher Engine: An algorithm has been developed that, requiring only a few pieces of information from the user, identifies and evaluates the sail's shape lines, returning draft, camber, twist, entry and exit angle. Thanks to an intuitive interface and advanced features, SailWatcher allows you to focus on what you love most: sailing. The app is designed to offer you all the information you need, right in the palm of your hand. Download SailWatcher today and take your passion for sailing to a higher level! --- FREQUENTLY ASKED QUESTIONS - Which parameters does it calculate? SailWatcher calculates the following parameters: camber, draft, twist angle, entry angle, exit angle. It also saves the boat's speed at the moment the photo is taken. - Does it work on every sail? SailWatcher calculates the parameters of all sails with highlighted shape lines. If your sails have visible shape lines, you can use SailWatcher. - Is an internet connection required? SailWatcher is designed to be used on the open sea; it does not require an internet connection, except for some secondary functions (e.g. sharing). - Can I share the obtained data? Yes, via a unique URL. The web page will contain the photo, the shape lines with their parameters, additional data (wind speed, ...) and additional notes entered by the user. - Why can't I retrieve the data? SailWatcher performs a series of calculations to identify shape lines. If you can't retrieve the data for your sail, let us know by email. We will analyze the case and improve the algorithm so that it also identifies your sail.

Current Coach turns your iPhone into a precision tidal current meter for sailors, racers, and cruisers. Drop your phone into a waterproof drifter, let it move with the water for 30–60 seconds, and get the speed and direction of the current in real time. Whether you're calling the first shift off the pin, staying out of a foul current at the layline, or understanding why the boat felt slower on port tack — Current Coach gives you the data instead of the guess. KEY FEATURES • PRECISION MEASUREMENT GPS-driven drift readings with start-to-end displacement. Every measurement shows speed in knots and m/min, direction in degrees, duration, and a confidence score combining GPS quality, recording length, and drift distance. • GPS SIGNAL SCOPE Before you hit Start, a radar-style scope shows live GPS accuracy — color-coded green/blue/amber/coral so you know whether the first ping will be good enough to anchor the reading. • HEAT-MAP VECTOR FIELD Toggle heat-map mode on the map and Current Coach interpolates a full vector field of currents across your race area from the readings you've collected. Lookback adjustable 1–24 hours. Confidence fade shows where the extrapolation is strong vs. weak. • HISTORICAL REVIEW Tap any recorded measurement to jump to the map with a ±12 hour window focused on that moment. Retrace a tack. Compare morning practice to the afternoon race. See how the current evolved. • M2X CLOUD SYNC (OPTIONAL) Sign in with an m2xsailing.com account to sync measurements to the cloud. View them in the web File Library, share with teammates, or disconnect any time. All core features work offline without signing in. • DESIGNED FOR THE HELM Dark palette, large numeric read-outs, readable under sunlight. Portrait-locked. Recording continues while the phone is pocketed. No ads, no subscription, no in-app purchases. Built for sailors who need the answer, not a guess.
