# LuckyDirectionMap vs VesselView Mobile

The clearest difference is rating: LuckyDirectionMap at 4.5 against VesselView Mobile's 3.1. LuckyDirectionMap also leads on update cadence (every 5 days vs every 3 months). VesselView Mobile's advantage is in-app purchases (none vs 10) and ratings volume (146 vs 21). On price, ads and device support there is nothing between them.

Both are free to download. LuckyDirectionMap sells 10 one-off in-app purchases. VesselView Mobile asks for nothing beyond the download.

LuckyDirectionMap holds the better App Store score, 4.5 against 3.1. That said, the two scores are not equally well evidenced: VesselView Mobile has 146 ratings behind it against 21, so its average is the more settled of the two. Written reviews complicate that: 38% of LuckyDirectionMap's written reviews are positive against 47% of VesselView Mobile's, so the app with the better star average is not the one people write more warmly about.

LuckyDirectionMap ships an update every 5 days, VesselView Mobile every 3 months. The most recent releases landed on September 16, 2026 and September 20, 2026 respectively.
