Sailing Analyzer

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.
What the numbers alone cannot show, you can look back on with photos and videos tied to your track.

[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.
- Import the photos and videos you took during practice, and keep them tied to the moment you were sailing.
- 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)
- Totals across four groups: upwind/downwind by port/starboard
- Automatic wind direction estimation (filled in when you finish measuring, and you can correct it by hand)
- Measurement data display function (leg list, map display, graph display, estimated wind direction at each tack)
- Graph types (speed, sailing angle and VMG over time; speed, VMG and time spent by angle)
- Measurement data editing function (wind information, boat information, notes, GPS data range, division of measurement data)
- Photo and video function (linking to logs, adjusting the capture time, capture points on the map, video trimming)
- Shooting with speed and heading burned into the photo or video
- Recording of boat information (boat information, tuning information, setting photos)
- Comparison function with past records and teammates (up to six logs, synchronized playback)
- Exporting and importing logs as CSV
- Unit settings (distance: m/km/mi/nm, speed: m/s/km/h/mph/knots. Wind speed can be set separately from speed)

[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, along with imported photos and videos, is saved inside the smartphone. Please note that data cannot be taken over when changing smartphones.
- Do not operate this app while sailing because it is dangerous. Only shoot when it is safe to do so.
- 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.
