Depending on your mobile device's OS, visit the corresponding store to purchase, download and install the MarineTraffic Mobile App.
Google Play (Android)
App Store (iOS)
Windows Store (Windows)
Upon installation, you can directly start using the App. However, it is highly recommended to sign-in or register in order to make full use of the App's available functions and features.
To sign-in or register tap Menu->Settings->My Account->Login
If you are an already registered MarineTraffic user, you can use your credentials to sign-in to the Mobile App (the same way you would sign-in to the MarineTraffic website). Enter your e-mail and password and tap on the "OK" button.
If you are not a registered MarineTraffic member, you can do so by tapping on the respective button. Registration is completely free and can be completed in a matter of seconds.
Either way, you can now start enjoying the MarineTraffic Mobile App to its full extent!
