ReceptionRating · Positive reviews · Number of ratings

Ocean Keeper holds the better App Store score, 4.4 against 3.8. That said, the two scores are not equally well evidenced: Ocean Keeper has 288 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 86% of BoxHead vs Zombies 2's written reviews are positive against 48% of Ocean Keeper's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

BoxHead vs Zombies 2 ships an update every 13 months, Ocean Keeper every 4 days. The most recent releases landed on September 25, 2026 and October 19, 2026 respectively.
