GPS only required for real time route navigation. Optional Real time AIS, Tides and Weather information require an active internet connection. Real-time route navigation requires a GPS location. iPhone devices and iPads with a cellular modem already have a built-in GPS, even if they do not have an active service plan. If you have a WiFi-only iPad or iPod you will need an external GPS receiver to enable navigation. Inexpensive 3rd Party units are available to add these accurate location capabilities to your device via bluetooth. Please note that continued use of GPS running in the background can dramatically decrease battery life. NOT FOR NAVIGATION This program is distributed in the hope that it will be useful. SeaNav should only be used for basic navigation reference and should not be solely relied upon to determine precise locations, proximity, distance, or direction.

SeaNav US App Reviews

  • Poor & slow

    By Pet Gear Depot
    Crash & calibrate,seems that's all I do with this app. This app is not even good for recreational boating. Don't waste your time & money.
  • Crashed 5 times in the first 15 minutes - Yuk

    By D_Snow
    Crashed so often that I couldn't even view harbors. Vey allow on my LTE iPad Mini. Depth contours 0-18', 18-30', and 30-600'are less than ideal. I would want to navigate my boat using this app and its maps.
  • Good app but NO detailed depth contours for Tennessee River

    By Flexoffset
    I give it 5 stars because it is an intuitive app, and if you do any type of weekend trip on a cabin cruiser near the major bays, it's probably fine. I like the fact that it pings GPS every minute when in background mode to save energy. I like the intuitive interface, and myriad options one can set. Their tech support is great. I've been emailing them and they have done all they can to work with me, and even suggesting a refund. I appreciate a company like this but I did ask them to update their description to make sure people know about the Tennessee River depth contour issue. I bought a competing app after I bought SeaNav and I initially considered refunding the SeaNav but I like it enough reasons to keep them both. I'm not a pro but I have spent a lot of my life in twin engine Chris Craft cruisers as well as little runabouts. I keep laminated official marine charts and realize these apps are no substitute for charts. I CANNOT RECOMMEND THIS APP FOR THE TENNESSEE RIVER, particularly for its lack of detail upriver from Pickwick Dam (Pickwick Lake towards Wilson Dam) and lack of more detailed depth contours. There are underwater stumps galore and you must stay in the channel you need to follow. SeaNav does not show a route and does not label any of the obstructions - even though it would probably be impossible to pinpoint them all. I bought this app for the depth contours that showed up in the preview images, thinking they would be on all US waterways. Seems their map source does not offer those, so I get only two depth contours on the Tennessee River through North Alabama: >9ft and <9ft. Seriously. Inaccurate rendering of depth contours even in slews that are 20+ feet deep it is a blue color representing <9 ft deep. We do a lot of activities in our runabout in shallow slews and also a couple miles up from the mouth of the Elk River. The mouth of the Elk River has channel markers but this app does not show a route through that channel. The river renderings stop after you leave the main Tennessee River. Elk River on Wheeler Lake? forget it. Shoals Creek on Wilson Lake? forget it. Bear Creek on Pickwick Lake? forget it.
  • Snappy and helpful

    By gschroder
    The app is crisp and responsive on my 4th gen iPad -- and the AR feature was a huge help in confirming landmarks while sailing through the fog along the Monterey coast.
  • Nice improvements

    By SuperSaint2009
    They keep working on this app and its become much better, performance is good on my iphone 5
  • Unusable

    By Appkiller434
    The charts draw soooooo slowly, this app is virtually unusable.
  • Too slow and crash prone

    By RafaU
    It crashes about half the time thus far
  • Slow to the point of being unusable

    By Layr Layr
    The slightest move on the chart causes a 5-20 second wait for the map to redraw itself. Zooming out makes the map unreadable for at least as long. Simplifying the map only helps a little bit...still too slow to use. The charts are way too busy graphically speaking-very hard to even find a channel with giant marker icons. The only good thing is that is coordinates with boat beacon, a very good app. Get Navionics. 1000 times better.
  • Crash

    By Z090
    Will not run on my 124g iPad3 more than two minutes before crash.
  • Crashes frequently

    By JFNeal
    I am running this app on an iPhone 5 with iOS 7. Since purchasing I haven't been able to use the app due to it crashing every time I open it. Please update your app to work with the new iOS or remove it from the App Store if you cannot support it.
