Verdict

The call

The clearest difference is in-app purchases: Sushi Monster at none against Fourth Grade Learning Games's 7. Sushi Monster also leads on review sentiment (71% vs 48%) and update cadence (every 5 weeks vs every 4 months). Fourth Grade Learning Games's advantage is ratings volume (13K vs 815). On price, rating, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Fourth Grade Learning Games holds the better App Store score, 4.2 against 4.1. That said, the two scores are not equally well evidenced: Fourth Grade Learning Games has 13K ratings behind it against 815, so its average is the more settled of the two. Written reviews complicate that: 71% of Sushi Monster's written reviews are positive against 48% of Fourth Grade Learning Games's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Sushi Monster ships an update every 5 weeks, Fourth Grade Learning Games every 4 months. The most recent releases landed on October 21, 2026 and October 29, 2026 respectively.
