An intuitive, easy to use tactical mobile application for sailors by sailors. Built and optimized for iPhone, Apple Watch, and iPad. Maximum feedback with minimal user input. Easy to use interfaces with highly visible displays.
Distance to line, tactical pre-start data, and a race dial that tracks wind shifts and headers! We are happy to announce that all these features are also available on the Apple Watch.
At tack X, our mission is simple. First, we provide sailors clear and concise data in all conditions. Second, we foster the improvement of sailing skills and a lifetime of learning through technology.
Not only do we write and test the software for our customers, we use it too. Every member of our team uses tack X. Our continuous field testing process means a better experience for you.
Not a racing sailor? Not a problem there are features for you too! Use the nav display for position and course information. Use the "line manager" to calculate distances and times to coordinates. And more!
