Everything you need on the water
One app for tracking ships, finding ports, spotting lighthouses, and knowing where you’re headed.
Live AIS map, worldwide
Every cargo ship, tanker, passenger liner, fishing boat, tug, military vessel and sailboat on the water — color-coded by type and moving in real time on a map you can pan and zoom anywhere on Earth.
Find any vessel in seconds
Search by name, MMSI or IMO number and jump straight to a ship’s position, speed, heading, course, destination and ETA — no scrolling a map to spot it yourself.
Ports, at a glance
Browse a bundled database of ports worldwide with berth details, traffic, and the ships currently calling — useful whether you’re tracking a delivery or just curious what’s in harbor.
Lighthouses & navigation aids
A full lighthouse and nav-aid database with location, light characteristics and range — for sailors, spotters, and anyone who likes their coastline annotated properly.
Marine compass
A real-time heading compass built for the water — orient yourself against true north wherever you are, no separate app required.
Favorites & fleet tracking
Star the vessels, ports and lighthouses you care about and check back on them from one list instead of searching again every time.

Built on real AIS data
Not a toy map. Marine Tracker is grounded in the same Automatic Identification System data merchant and passenger vessels are required to broadcast worldwide.
Privacy-respecting
Your location is used on-device for the compass and map centering — never sold.
Global coverage
From major shipping lanes to small harbor traffic, worldwide.
Always current
Positions refresh continuously as vessels broadcast their AIS signal.
Questions, answered
Where does the ship data come from?+
Vessel positions come from AIS (Automatic Identification System) transponders that ships broadcast by international requirement. We aggregate this through a licensed vessel-tracking data provider and refresh it continuously, worldwide.
Is Marine Tracker free?+
Yes. The core map, search, ports, lighthouses, compass and favorites are free with light, non-intrusive ads. Marine Tracker Pro removes ads and unlocks weather overlays, AI vessel summaries, port alerts and full unblurred data fields.
Can I use this for actual navigation?+
No. AIS data can lag, drop out, or be reported incorrectly by a vessel’s own equipment. Marine Tracker is for informational and tracking purposes only and must never be used as a substitute for official navigational charts or instruments.
What languages does the app support?+
Marine Tracker ships in 11 languages: English, Deutsch, Español, Français, हिन्दी, Bahasa Indonesia, Italiano, 日本語, Português, Português (Brasil), Türkçe.
Does it work on both Android and iOS?+
Yes, Marine Tracker is built for both platforms from a single codebase, so the experience matches wherever you run it.
