[Analysis App of the Sailors, by the Sailors, for the Sailors] Taking advantage of my experience as a sailing athlete and coach, I have created an app that can be used to improve sailing skills. I hope this app will help improve the quality of practice. [How to use] - Record the wake using the GPS sensor of your smartphone. Bring your smartphone to the ship and take measurements. - The app will automatically analyze the measured wake. - Check the analyzed results, improve tunings, and use it for the next practice! [Main functions] - GPS measurement function - Analysis function (time, distance, speed, number of tacks, number of jibes, sailing angle against the wind, calculation of VMG) - Measurement data display function (leg, map display, graph display) - Measurement data editing function (wind information, boat information, manual correction, division of measurement data) - Recording of boat information (boat information, tuning information) - Comparison function with past records [Disclaimer] -Since this application operates with GPS, the accuracy may deteriorate depending on the surrounding radio wave conditions and the performance of the terminal. - Estimated wind direction is automatically input. If necessary, correct the wind direction manually. - Measurement data is saved in the database in the smartphone. Please note that data cannot be taken over when changing smartphones. - Do not operate this app while sailing because it is dangerous. - The app developer is not responsible for any disadvantages such as accidents or injuries while using this app. Please be sure to use this at your own risk.
