iSailGPS : NOAA USA RNC Charts

Replaces a basic chart plotter. I run in the dark quite a bit, and this app has been very accurate for me. I’m always impressed - basic functions, but it performs very well.

Any of the negative reviews, and there are only a few, cleary just downloaded the app and didn’t bother to learn it. This app is amazing! I do wish I could figure out how to download additional waypoint icons though. Anchorage, bouy, ramp, hoist, pump out, etc. it may be possible but I can’t figure out. Still tho, great map. One tip, when creating waypoints, make sure to use in insets or zoom way in because, initially, when I was creating them, I learned that they were way off!

I just wanted an app that I could use for viewing NOAA raster charts. This does the job plus so much more. I like that you can download the charts right to your phone so they are always available whether you have cell phone service or not. The app itself doesn’t take up much space on your phone which is another plus. For under $10 you can’t go wrong with this app folks.

I love this app! It gives me exactly the info I need when racing or just sailing. I’ve set waypoints for all the government and private buoys we use to set our race course. Then all I have to do is create a route by choosing the waypoints to be used for that day’s race. Then I have SOG and bearing and VMG to each mark and more. Amazing! The learning curve is a bit steep, but well worth it. And if I have questions, the developer is super-quick to respond. Highly recommended.

I have used this app on my phone to navigate my sailboat at night from San Diego to Catalina and arrived at Avalon dead on the mark and within five minutes of the predicted ETA. While it’s less convenient than a dedicated chart plotter, it gets the job for a fraction of the price.
