# Sushi Monster vs Fourth Grade Learning Games

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.

Both are free to download. Fourth Grade Learning Games sells 5 in-app purchases, starting at $5.99 per month. Sushi Monster asks for nothing beyond the download.

Fourth Grade Learning Games holds the better App Store score, 4.2 against 4.1.

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.
