Sail Tracker is an app to track your Sailings and keep them in your Sail-Board (digital logbook) at Sail-la-vie.com. The app is used to track route sailings. Either sailing club members or Sail-la-vie.com customers can use this app to record, when they are at sea, the route they follow. The track is done using the GPS of the phone and the data are stored first locally and then transmitted to a server where the users can see their routes and share the URL to family and friends. This URL is called Live Map in the app. It is a join cooperation of HARTIS, SAIL LA VIE and SAIL-CLUBS.com. You need to login first to Sail-la-vie.com in order to use the app. You may read more about the concept here: http://www.sail-la-vie.com/#enjoy
SailViewer

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.

The clearest difference is iOS requirement: Sail at 8.0 against SailViewer's 17.0. On price, update cadence, ads and in-app purchases there is nothing between them.
