A friend of mine recently downloaded the eSeaChart App onto his smart phone and has nothing but good things to say about it. I have not used it or even seen it yet, but thought I would pass along the information.
eSeaChart has been built with speed and responsiveness in mind. This not only makes the app feel right, it’s also essential when using the app on a moving craft. When at the helm it’s essential to keep your eyes outside the craft at all times, and every second spent fighting a slow app is seconds lost keeping a proper lookout. eSeaChart automatically switches between charts as you pan and zoom.
eSeaChart uses NOAA raster charts which has the same look as the traditional paper charts. They also provide full coverage of the United States maritime territories.
NOAA update many charts on a weekly basis. eSeaChart downloads the maps directly from NOAA without middle hands, ensuring that you always get the latest and most up to date chart. And you can update the chart by simply downloading it again, at any time.
A lot of effort has been put into the app, making it as simple and easy to use as possible, without losing its usefulness. Just download the charts you want and start navigating.
