iSailGPS : NOAA USA RNC Charts

September 18, 2024

This version is ready for iOS 18 and the newest iPhones and iPads. We're continually improving this app so it will be even more useful! What's new in iSailGPS when compared with other available NOAA chart apps? • You don't just see waypoints and routes displayed on the chart, you can actually do real great circle navigation to those waypoints and along those routes. You get information such as Estimated Time of Arrival, current bearing, heading and cross-track error, and remaining distances to your intermediate and final destinations. • You don't just see individual charts. Whenever the map projection is compatible (which it is most cases), you can see adjacent charts with their margins removed stitched together seamlessly, even when the chart scales are different. For example you can see the approach chart and the corresponding harbor detail chart both together on the same screen. • You can create, import, edit, export, and navigate both on routes based on a recorded or imported path, and on routes based on a series of waypoints. • Get the weather report and forecast, the sun and moon position, rise and set times, and driving directions to the dock for any point on a chart with a few taps. • iSailGPS's code size is kept very small by efficient programming so in an emergency, you can download it easily even over a weak cell connection. • The current version of iSailGPS runs on the latest devices and also on older devices with older versions of iOS , all the way back to devices such as the iPhone 6. • There is never any confusion over what charts you have available offline. They are clearly listed by NOAA chart name and number, and shown on an overview map. • Check the App Privacy section. We don't know who you are when you are using iSailGPS. We never send your current location or your recorded track to our servers. Hence we cannot and don't use your location data. We cannot and don't provide your location data to anyone else. Unlike other mapping apps that profit from using your location data in ways that do not keep it private, iSailGPS maintains the highest level of data confidentially.
