Live-Daten von Schiffen, hat für mich eigentlich keinen Mehrwert, finde es aber super interessant. Das geht auch über die Website, aber es ist schon cool im Urlaub (lol) am Meer sagen zu können wie das Schiff am Horizont heißt, und was es macht.
Grundversion ist kostenlos, aber man kann in-app ein Upgrade kaufen.
Looks like the Android version is $6 and the iOS version is $5:

I have a free knockoff app called FindShip which has limited ads. But yeah I've never seen the original MarineTraffic app available for free. Their desktop site is free though and is quite good.
He might enjoy Marine Traffic as well then
