Sailing Analyzer vs SailViewer

[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. 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.

SailViewer turns sailing GPS and instrument logs into an interactive debrief on iPhone and iPad. Import a supported sailing file, choose the logs you want to open, and explore the race from several angles: • Track views with boats, courses, selections, and optional map backgrounds • Tables and graphs for comparing selected values • Polar analysis for speed and angle relationships • Start, Race, Boat, and Maneuvers views when supported by the data • Local image sharing from supported analysis windows SailViewer includes synthetic sample logs. Samples start closed, so you decide when to open them. You can import SW2, SLV, GPX, KML, NMEA, VTK, FIT, VKX, supported CSV sources, and supported ZIP archives. Your imported sailing files stay on your device unless you explicitly share them. Ordinary iPhones, including large iPhones, have permanently free local access and do not require weekly license checks. All iPads, including iPad mini, and this iPad app running on an Apple-silicon Mac are free through 31 December 2026. These devices require an internet connection for initial activation and at least once every seven days. Free access ends on 1 January 2027 at 00:00 UTC, when a paid subscription will be required. Purchasing will require a future app update; this release cannot take payments. There is no automatic charge. If access expires, your local library is retained. Optional error reports and usage summaries are off by default. Support reports are sent only when you choose to send them, and original sailing logs are not attached automatically. This is the new SailViewer app and is separate from the legacy SailViewer/TruSailViewer product. Automatic transfer from the legacy app is not promised; keep your original files and import supported formats into this app.
