What's New in iSailGPS NZ

9.6.9

April 24, 2026

Improved wording on some Alerts and Notifications. What's new in iSailGPS NZ when compared with other available New Zealand 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 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 NZ'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 NZ 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. Check the App Privacy section. We don't know who you are when you are using iSailGPS NZ. 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 NZ maintains the highest level of data confidentially.

Awesome!

Have used for 2 summers now & very happy with it. Being able to select track up as well as North up would be a useful feature.

Excellent

We have used iSail GPS NZ since we retired our home-built charting software. We thought we were smart, but iSail GPS NZ has impressive functionality delivered on a very usable platform (iPad). Recently had an issue with the iPad – my fault – and so contacted support. To say Larry was helpful is an understatement. His responses were prompt and comprehensive. Very much recommended.
