SeaNav is a Universal app, which works on iPad, iPhone and iPod.
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 has free Apple Watch and Pebble Smartwatch apps available.
Lowrance, Simrad and B&G GoFree support included.
Your purchase of SeaNav includes 12 months of free updates to the included US chart set. Further chart updates are then available via an in-app purchase. Charts for other regions including Canada may also be added to your product via optional in-app purchase.

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 or iPod 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.
