User Reviews

Overall, users praise iSailGPS for reliable NOAA raster charts, solid GPS tracking and waypoint/route features, and strong value. The app is battery friendly, stable, and well-supported, with reviewers noting quick responses and good updates. It’s trusted for night sailing, racing, and cross-device use between iPhone and iPad. However, chart stitching/management, inland coverage gaps, limited chart detail/zoom, and occasional chart loading issues are recurring drawbacks.

Great App! Had it about 6 years now and it’s awesome, nothing better available in its class!

I miss charts. This is by far my favorite app for sailing. No distractions, just clear accurate markings on a proper chart!

The main problem for me is the inability to stitch together a see less chart and being able to get the best detail for the area automatically. I’ve been playing with app for awhile now and when I get to the chart boundary I can often get the next chart to show by double tapping the white area outside of it. And sometimes, I think, it seems to have successfully stitched together into a single, larger chart. But, it may not have the sufficient detail I need for a particular port. At that point I’m forced to go to my downloaded charts and find it. Not so simple as I now have a long list of charts. This can be impractical to do on the water unless you have a dedicated navigator. When approaching a busy area I don’t want to take my eyes off the water and be scrolling through a list of charts trying to find the appropriate detail. Maybe I’m missing something but for me other apps with paid subscriptions work a lot better. There’s just no chart management needed, and you can find them for as little as $5/year (at least for my area - eastern US coast).
