Awesome!. This app saved us last night in the fog. Got home safe thanks to this excellent app!

Unusable. The charts draw soooooo slowly, this app is virtually unusable.

Nice improvements. They keep working on this app and its become much better, performance is good on my iphone 5

Too slow and crash prone. It crashes about half the time thus far

Exceptional. Love the look and feel of the charts. Easy to read. Zoom in and out makes my onboard Raymarine software/equipment a relic. Use in conjunction with Boat Beacon (app). This will give you real time AIS!

Crashes!!!. when you set sail to a point it crashes and then you have to start all over. Adding spots should be simple but its not, (you should be able to tap in boat position and add your fav spot), zoom in out is app took a time to load or freezes!

Too basic. This app offers little more than a colorful map with a few icons. It is of zero use in navigation.

AIS fan. Great app for viewing ships in Los Angeles harbor.

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.

Not user friendly. Very difficult to use but have heard good things from other Captians

Crashes frequently. 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.

Amazing app. This app is truly amazing. It automatically couples with other apps, like the AIS beacon app, et al.

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.

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.

Misleading. App is suppose to cover all US charts yet none of the lakes in my area show up. In fact, none of the lakes in my state show up, and we are talking some rather large bodies of water. The only body of water to show up is a floodplain called little blue river which isn't even navigable, lol. App should correctly read only select US bodies of water, not ALL U.S. charts. Waste of $10. Navionics is much more complete.

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.

Waste of money can’t get a river depth it old version was free. Google maps is better

SeaNav. Works best on iPad 3 with cellular/wifi as this iPad 3G has a GPS assisted capability whether connected or not to a cellular network. IPad 2 wifi (no cellular) dees NOT have a GPS Satellite Receiver in them so you would need to add a GPS receiver to an iPad 2. I tried using a Verizon Hot Spot Cellular with iPad 2 and neither worked, nor did Apple Maps or Google Maps. There are no cellular towers in the middle of Lake Michigan, so the triangulated cellular cannot function on a iPad 2. You end up sliding along the shoreline and never go out into the Lake. The same problem happens with Apple Maps and Google on an iPad 2 with wifi. Apple Tech Support acknowledges that they are having problems with Apple Maps and today acknowledged issues reported with SeaNav and BoatBeacon, both sold through their AppStore because of the lack of a GPS receiver in the iPad. I took back my iPad2 wifi and picked up a iPad 3G which allows SeaNav & Boat Beacon to work out on the water. The Technical Support and Management at SeaNav/Boat Beacon provided excellent support and personal attention to my concerns and answered all my help requests. A+

Self. Purchased app yesterday and initially worked perfectly, then my iPad wouldn't show position on SeaNAv. Strange. I emailed Steve Bennett @ Pocket Electric (the developer) and I had an email back from him this morning. There's a known bug in the llatest bersion of iOS software that prevents the iPad from accepting location from the extenral GPS (in my case, a Dual). The fix is on the iPad: (1) turn off location services on iPad; (2) reboot iPad; (3) wait 5 seconds and turn iPad on; (4) turn location services on. This may need to be done whenever the problem reappears. Let's hope Apple fixes this soon. Anyway, the SeaNav app is outstanding and a real bargain for the recreational boater, in my opinion. And the quick, accurate and friendly tech support seals the deal for me!

Hard to navigate. Hard to use

Very cool app!. I also have boat beacon that overlays AIS data on these nautical charts and its great to watch, especially during meetings when you'd rather be on the water :)

Crash. Will not run on my 124g iPad3 more than two minutes before crash.

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.

Awesome app. Huge fan of this app. Really easy to set up. Easy to use. Very functional. The app has a lot of great features. I holy recommend this app

Needs work. It would be a great app IF it would use iPad internal gps. At the moment it requires you to connect to external gps! How stupid is that?! I used version of this software back on PC. Back than I understood need of external gps. Not theses days. Please fix it. Meantime I will stick to iSailor.

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.
