The unique Augmented Reality view mode allows seamless overlay of buoys, lights, ships, waypoints, and tracks onto your iPhone or iPad live camera feed. The "AR LockOn" feature enables users to select targets on the chart for guidance in real-time AR display. This is particularly beneficial in low-visibility conditions such as night or fog.

The app's Head-Up Display (HUD) efficiently shows vital navigational information including position on route, Course Over Ground (COG), Speed Over Ground (SOG), Vector Made Good (VMG), Estimated Time of Arrival (ETA), as well as distance and bearing to the next waypoint. Features such as waypoint reached alerts and AIS collision warnings enhance navigational safety.

It is important to note that all in-app purchases operate as one-year subscriptions that automatically renew unless turned off at least 24 hours before the current period ends. Payment details are processed through the user’s iTunes Account upon confirmation of purchase.

The software requires an iPhone or iPad device; however, for full functionality related to real-time AIS data, tide information, and weather updates, an active internet connection is necessary. Users with WiFi-only devices will need an external GPS receiver to facilitate navigation.

Please be aware of potential battery drain when utilizing GPS services in the background.
