Verdict

The call

The clearest difference is rating: The Shark Trust at 5.0 against FathomVerse's 4.7. The Shark Trust also leads on update cadence (every 2 weeks vs every 6 weeks). FathomVerse's advantage is review sentiment (86% vs 67%) and ratings volume (92 vs 5). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

The Shark Trust holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: FathomVerse has 92 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 67% of The Shark Trust's written reviews are positive against 86% of FathomVerse's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

The Shark Trust ships an update every 2 weeks, FathomVerse every 6 weeks. Both last shipped on November 3, 2026.
