What's New in VesselFlow
1.0.2
August 8, 2026
Replay now lets you watch the last hours of traffic play back on the map. Follow a single vessel along its entire track, or replay a chokepoint to see how it fills up and then clears. Recent has been upgraded too: ports and straits now appear there alongside vessels, so you can jump back to the places you care about faster. iPad users get smoother map and panel resizing for a more stable, responsive view. We also improved reliability across the app, including search, watchlist names, replay playback, and map framing. Plus, bug fixes and performance improvements throughout for a faster, more consistent experience.
