The app tells me there is an update to the chart I purchased, but doesn’t give a download option, all I can do is delete.

I have used many navigation apps over the years and thought I was using the best one until a friend asked me to help him take his boat down to Hilton Head. His primary chart plotter died and he pulled out his iPad and started using Maptech iPlot. I was surprised at the amount of features it had and even more surprised on the ease of use. I have never used an easier navigation app before. I especially liked that it used the NOAA raster charts. I enjoyed using it so much I bought it and am using myself now.

Seems like a fairly useful navy app however I did not realize before downloading that they are NOT offering Bahama's coverage.

Thank you Maptech. Finally a Navigation App that use the updated NOAA raster charts! The other vector chart apps on the market lack the detail and accuracy provided by the original NOAA source charts. I like the ease of your seamless chart manipulation and the smart zooming and scaling. I like the simplicity of creating routes and i also like the Steer To screen with with range and bearing to waypoint. I hope that the next version of your App will have the ability to display the Maptech 3D bottom contour charts?

My husband and I are weathered sailors and have tried many of the new navigatin apps for our ipad 4. We were happy to find out Maptech has this app. We use the Maptech paper chartbooks as well as their PC programs and have come to rely on them for all our navigation needs. This app quilts the Maptech charts without any seems. It is easy to operate and handles routes and marks better than any app or program we have ever used. We would like to see the next version import our routes from our Maptech Chart Nav Pro program, let's hope they are working on that.

This is nowhere near the level of Navionics. It's cheaper, but not a good value. I saw it at the Annapolis Sailboat Show last weekend and bought it for a feature I like that Navionics doesn't have. That's the dashboard, which shows COG, SOG, and XTRK, time to next WP, etc., which I can use when racing. But this thing isn't stable. The maps are crude downloads of free US charts. They jump around. It's not a smooth app. Maybe I'll be able to use it in the limited context of a few race waypoints. It's inspired me to write to Navionics and ask them to add a racing module, maybe they'd charge ten bucks for that. But this app isn't the solution to your cruising chart needs. Get Navionics or Garmin BlueChart.

Functionality has improved significantly as Apple has corrected its OS. Using this with an iPad Air.

"This is what I have been looking for, an iPad app for navigation that is easy! Downloaded the iPlot app about a month ago, and loaded the free planning charts and Region 3. Been using it for a month now and really love it. Easier to plot routes with the iPlot than it is on my 6k chart plotter on my boat! The charts are much more detailed and up to date than what the plotter uses. The iPlot has all the functions I need to plot marks and routes, and it is so simple. I really like the steer by page, after I set my route up I use this to steer from waypoint to waypoint. I find myself navigating with with the iPlot more than the boater,s plotter. We'll done, Maptech.

I like this app. I don't understand why these previous reviewers had so much trouble. I just finished a two week delivery and this app performed really well. I am waiting for them to add tracks to the app. I promise you, this is much easier to use than InavX.

Spent 2 hours putting in waypoints and routes. App would not stay open...had to delete and reinstall...let's see if it works....paid a lot for 6 chart adds and I am very disappointed
