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.

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.
Developer Response
We are glad to hear SeaNav is working ok again for you now. Apple had an issue with their AppStore which was affecting a lot of Apps In App Purchases. They have now fixed it.
Too basic
Sunrise46
This app offers little more than a colorful map with a few icons. It is of zero use in navigation.
Very good navigation app
MV Kinnikinnick
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.
AIS integration
Ted in NC
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.
SeaNav autoroute:
Set start and end point for a route and let SeaNav propose a route and waypoints including the ICW
SeaNav AutoPilot:
Navigate routes automatically. SeaNav can now remotely control Raymarine and Navico/Simrad/Lowrance Auto tillers and helms. You can also use the free SeaNav Apple Watch app to control a Raymarine autohelm and tiller from your wrist.
iOS 26 updates.
