AIS integration
The integration with my em-trak AIS receiver/transmitter is the killer feature. That lets me do heavy-duty nav/piloting in the iOS/WiFi universe rather than in some manufacturer's proprietary OS universe and the nichey, expensive, specialized marine networking universe.
Removing ‘Crashes on open’ comment
SeaNav has always worked well for me but recently after updating my subscription it crashed on open for about 2 days on my iPhone 16. A reboot and reinstall did not help. However after this time the app works again. Upgrading review to 4 star but suggest not changing subscription during a stormy day out sailing.

Crashes on open
Since renewing the subscription for US charts this app crashes as soon as these charts load. Unfit for purpose.
Deceptive
Product doesn’t allow you to try before it charges you and then refuses refund. Beware
Hard to use
Difficult
Hard to navigate
Hard to use
Too basic
This app offers little more than a colorful map with a few icons. It is of zero use in navigation.

Very good navigation app
I’ve used SeaNav and Boat Beacon for six years, extensive offline use in British Columbia and Washington.
Of the six or seven IOS marine navigation apps I’ve owned, it’s the best and most enduring.
Well maintained and very responsive tech support.

Waste of money can’t get a river depth it old version was free
Google maps is better
Not user friendly
Very difficult to use but have heard good things from other Captians
Not for iPhone!
I sail Alamitos Bay in Long Beach, CA. Although I have Anchorages layer OFF, the chart still indicates all anchorages. So many are shown that they overlap and are unreadable. On my iPhone 6 Plus, the chart is useless. Tech support claims that the anchorages are the names of the 'water areas' and will show even with the Anchorages layer turned OFF. $30 bucks out the window, as far as I'm concerned.

Poor & slow
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
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
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
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
They keep working on this app and its become much better, performance is good on my iphone 5
Unusable
The charts draw soooooo slowly, this app is virtually unusable.
Too slow and crash prone
It crashes about half the time thus far
Slow to the point of being unusable
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.
