Marine Navigator

Excellent chart app that I use with charts from "Visit my Harbour". Setup is a little tedious but only needs to be done once. AIS demo mode works. Hope author rolls it out quickly.

Amazing app. Turns your smart phone into a fully functional navigation device. I had used the lite version to navigate all over the Great Lakes for the past three years and just upgraded to the full version. Don't delay like I did! The functionality is amazing.

Downloaded app and then bought charts for UK. Over 20 attempts, closely following the instruction but neither my son nor I could get the app to pick up the charts. Am asking for a refund as the app/charts don't work on a Samsung S7

An excellent app that works well with the UK charts from "visit my harbour" website. Looking forward to using the AIS overlay that has just been released. Well done!

Installed on Galaxy S8. Cursor coordinates do not match actual chart coordinates. Not sure how helpful this will be. Otherwise looks like a nice app.

My favorite boating app. Cant wait for the official ais upgrade to be available, I already ordered a nmea 0183 wifi bridge to feed my ais to my phone and tablet. I only wish there were more sources for kap files. Searching for usable maps apart from whats in the handful of websites listed in the import section is near impossible, I just cant find maps for most of where I want to sail outside of the USA. I'd pay more for a worldwide directory of usable kap files, even if I also have to pay separately to actually download them.

When I reset my device my charts disappeared, but managed to get them back after another reinstall, followed by import and new Activation Request. Thanks for your help!

Fantastic app! Better than a $2000 chart plotter. Takes a while to load up the apps; definitely do it ahead of time. Absolutely great to have real charts in my pocket when we're sitting at dinner, planning the next day's sail etc. I got a clamp mount for my tablet, and now I have a big display hands free at the helm. So good, I think I'll run a usb charger out and maybe skip the chartplotter.

I have used this app for years now. I love that it is offline, meaning you don't need a phone connection to use it. Out of phone signal? No problem, as long as you already have the appropriate charts downloaded and your phone has dedicated GPS, which almost all do these days. It's intuitive and therefore easy to quickly learn. Downloading Raster charts is relatively easy from NOAA in the US.. The layout of the display is great, and the zoom features take me into the very level of detail I need in a given situation. It has never given me a problem and I have now used it on several different phones. Never once has it glitched. I am actually shopping a tablet now with GPS to provide a bigger screen then my 5.5" phone, (though I don't really need it). They are available online for $60-$90. That compared to 400-1000 or more for dedicated marine unit. You can't ask for more than that. Best app I have on my phone.

Best navigator I have tried. I particularly like the excellent image quality on a tablet and the ability to easily freeze the chart selection to be able to zoom out for an overall view. Well done.

The app hasn't worked since the last Android update several months ago. The author has not released any updates so obviously has no intention of fixing it. Don't waste your money.

Excellent backup to a chart plotter. Uses free government-issued charts. The user interface is reasonably intuitive.

Love it and travel all over the world with! Only improvement would be able to store charts on sd card for more room.

By using NOAA charts a user connects with hundreds of years of British and American sailing experience.

Great app. Should add support for SD card storage.

No charts for Asia PG n far east

Works welll. Uses official maps. Perfect

Great app - using it with UK charts from Visit my Harbour

It does the job

IMHO this is probably the best RNC navigation app that uses official RNC charts directly from their respective sources. For voyage planning purposes this app runs circles around professional ECDIS machines costing tens of thousands of dollars more. I purchased this app over 5 years ago. Mr. Koenig keeps improving and updating this app over the years and has implemented several suggestions I have made a few years ago. In addition to planning, I also use it to verify that the vessel is on course no matter where I am on the vessel (even inside with a marginal GPS signal near portholes). I have not observed any deviation when comparing it against IMO type approved equipment. -- I am a USCG licensed professional mariner with an unlimited master's license (Any Gross Tons, Oceans) since 1999 with 30 years sea experience.

Not totally intuitive to set up but worth the effort. It works really well with some slight niggles. Blanks on adjacent charts when working away from vessel position is a bit unnerving. Would love to see NMEA integrated and then thus would get 6 out of 5.

This is a very good app for daysails, maybe. But for coastal travel it is too ponderous. There needs to be a way to import more than one chart at a time from the bsb_root folder. I would rather press a SELECT ALL button (or check the box that means to select all in a list view) and have to walk away for an hour or two, than to sit there and select them for import one at a time. I would even prefer, since you do not use the downloaded NOAA file directly, to have a separate app to do the conversion and import to the default list of all charts that appear in the bsb_root folder automatically. This would save a tremendous amount of time. Either option would serve to automate the mind numbing process a little.

Been using the light app for quite some time maybe 2 years and have finally decided to go with the paid app. Also used the lite app with great success in both rivers and In Shore. I anticipate this version will be more Dynamic

Used this for 2 years with VMH charts. After using Transas software on PC, this app is very usable, used it to navigate from Great Yarmouth UK south past Harwich Thames, Dover to Plymouth. It never faltered unlike the Garmin plotter.

Buy it. For $10 you are set up with a first rate plotter. Lite version works 100% and will get you there but the full version is a great deal. I purchased it as a token of graditude to the developer for making the lite version a working app. Love it.

Have used this App for Day and overnight passages in NZ waters, works well and is reliable.

Thanks for the great app! I use it constantly.

Best Chart and plotting app in the Play Store!!

Yes, yes, oh yes, Baby like app, Baby buy app NOW! Oh yes

Good navigation app for using with VMH Admiralty Charts

Invaluable.

Very accurate and simple to use

Nicely executed app, and when twinned with the VMH charts for European waters is an excellent alternative chart plotter. I love the way the app zooms from large scale to small on raster charts letting me see all the notes that are tough to pick up on vector charts. One plea for the next release. Please add an AIS display and connection to the boat systems. That way this could be my sole plotter for low power draw on passage.

Just started at home with app on Samsung Tab 3. I must be dense; I set some waypoints but see nothing anywhere explaining route planning. Nor have I seen the phrase "go to". I have not seen any trace of the three dashboards shown/described. I loaded NOAA charts OK I think (twice, it appeared) but none show the green checkmark described. I get that there is a learning process, but this thing is way short on instruction. I guess I'm only out $8.40, still very disappointed so far. Is there an MN for Dummies out there? -TC

Great app, although there is little learning curve to get used to things. I wish there was a quick tutorial. Here are two notes: First, it takes a while to import maps, so be prepared to let your device sit while while it imports the vector files. Each map was like 5-10 minutes so I definitely want to plan ahead for this. Second, I wanted all my relevant maps in the same folder zip file, because that way they will all show up in the same folder for the automatic switching. If I import each map in a different folder zip file, it's more cumbersome to switch back and forth. After selecting a new folder, I have to quit the app and restart it (which is fast) for the map auto-switching to take effect. Overall, this is a truly awesome app, bringing in the high quality NOAA charts aligned with GPS capability to see exactly where I am. Thank you for putting together such a great app.

App loads NOAA charts nicely. However, with an external GPS (tablet does not have an integrated GPS) no position is marked by this app. Google Maps is able to mark position with both the USB and Bluetooth external GPS units I use. Disappointing.

I have used this program with the VMH charts for two years on my Hudl 2 Android tablet and think it is excellent for coastal and open water navigation. I prefer it to the Navionics app I also have. I am planning to take it on a passage from Plymouth to the Cape Verdes as a back-up. The only problem I have is the tracks not showing, but could well be a Hudl glitch Thanks very much for a great app.

I use MN with VMH charts. It's a pretty good combo, but if I were to be picky I'd identify a couple of irritations: first, although you can save tracks, I can't see a way to view them; second the route editor allows you to append or prepend waypoints (in one menu), and to append, prepend or insert route points (in another), but you can't insert waypoints. But these really are quibbles in that the MN/VMH combo gives you a full up-to-date set of charts and a fullspec marine grade chartplotter.

I find this app pretty intuitive. It's simple enough my kids know to use it. It's great for the US as the digital charts are all free from NOAA. This not the case with other countries like Canada. I've had this app for several years now. An upgrade added many new features. A great app got much better.
