SeaNav uses Digital Vector charts providing a wealth of benefits and advantages. Buoys, Lights, Bridges, Depth Contours, Depth Soundings, Rocks, Anchorage areas, NOAA Weather Buoys etc. are all selectable and have real time distance, bearing and detail information. Turn off layers to de-clutter the display and only show what is important at the time. Tides, moon and sun times and weather are also all available at your fingertips.
SeaNav’s unique AR view mode allows you to view buoys, lights, ships, waypoints and track overlaid on your iPhone or iPad live camera view. With "AR LockOn" you can select a target on the chart and then be guided to it in the AR camera view.
SeaNav lets you measure distances and bearings and record waypoints on routes. When at sea, the app’s Sailing HUD shows your position, Course over ground (COG), Speed over ground (SOG), Vector Made Good (VMG), Estimated Time of Arrival (ETA), Distance and bearing to next Waypoint. Waypoint reached alerts, auto-routing to the next waypoint and collision alerts.
SeaNav comes with a free Apple Watch companion app .
Lowrance, Simrad and B&G GoFree support included.

Requires iPhone or iPad. GPS only required for real time route navigation. Optional Real time AIS, Tides and Weather information require an active internet connection.
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 you will need an external GPS receiver or GPS feed to enable navigation.
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.

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.

Deceptive
Product doesn’t allow you to try before it charges you and then refuses refund. Beware

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.

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.

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.

Unusable
The charts draw soooooo slowly, this app is virtually unusable.
Appkiller4342013-11-08
★★★★★
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.

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.

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!

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.

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.

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!

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 M

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 :)

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
