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.
