Great start for new (to me) nav app


I just got back from a week of sailing. Part of this frist cruise for the season was to evaluate the current state of navigation software. I was running between 2-4 different products at the same time and evaluating which worked and which worked best for me.

I kept coming back to Embark because of its very nice UI and how simply visually appealing it is. In lots and lots of hours of using it, it never crashed on either my iPad or iPhone. As long as you have strong cell signal where you sail you really don't need to buy any of the very reasonably priced subscriptions. But even there the buy-in is very modest. You can subscribe to a month worth of a service to give the advanced features a try. I.e., you don't need to throw down $60 for current charts.

From my perspective there are some things "missing" from the app (it is only a couple years old). I kept a running list of things that I would like to see or did not work as I expected. When I got back I sent my list to the Embark folks. I got an immediate response from them. Although I don't know that any of my ideas will become reality, I really think that my email is being discussed around a table someplace in Norway this morning. Great customer service and interaction.

No, I am not deleting the other apps from my iPad ... yet. But I am really looking forward to using Embark this summer and watch how it matures.

Great job Embark folks!

Perfect for boating, navigation and fishing!


Hardly use my chart plotter anymore. Having my charts on my phone is simply more convenient.
Embark offers incredibly detailed charts to navigate with. It´s possible to adjust the depths and heights personally that will be shown on the chart. It works perfectly smooth on the water, shows my location and is very easy to understand. I go fishing a lot with my boat and knowing the depth where I am is crucial to know. Being able to have all that information in a beautiful map… it is what I´ve been waiting for. I haven’t gone boating at night a lot, but the night mode works very well at dusk and dawn as well and the charts are incredibly easy to read! Great product!

Slick and fast


While this app does not -yet- have a lot of features, it is a pleasure to use. Attractive easy to view charts, fast scrolling and night mode. The company was just acquired by C-Map, the cartography company, which has the resources and power to take this to the next level. My priority list would include NMEA 2000 integration allowing connection to a vessel’s instruments and other monitoring. AIS, GPS, engine data ...
I would also like to see a service from them that delivers global weather conditions and forecast via a satellite service such as Iridium Go.
