SailWatcher vs TackSense

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.

TackSense is a simple sailing aid that helps you understand your point of sail from wind direction, boat heading, wind speed, and gusts. Enter the conditions, and TackSense shows a clear visual guide for the sailing angle, likely sail position, reefing considerations, and downwind caution zones. It is designed for quick use on deck when you want a fast sanity check without clutter, accounts, or unnecessary complexity. TackSense can help you identify whether you are close-hauled, reaching, running, near the no-go zone, or in a wing-on-wing zone. It also provides practical trim suggestions such as when sails should be trimmed in, eased out, or when a more conservative setup may be appropriate. Features * Point-of-sail calculation from wind direction and heading * Wind speed and gust input * Clear sail-position diagram * Main and headsail setup suggestions * Reefing considerations based on wind strength and gusts * Downwind caution notes, including wing-on-wing and gybe risk zones * Simple terminology for newer sailors * Works on-device * No account required TackSense is not a chartplotter, navigation system, weather service, or replacement for seamanship. It provides general sail-setup guidance based on the information you enter. Always consider local conditions, sea state, crew ability, vessel setup, and official weather information before sailing. Built for sailors who want a fast, visual answer to a basic but important question: What point of sail am I on, and how should the sails roughly be set?
