Verdict

The call

The clearest difference is review sentiment: Math Gremlin at 100% against Fourth Grade Learning Games's 48%. Math Gremlin also leads on update cadence (every 2 months vs every 4 months). Fourth Grade Learning Games's advantage is ads (none vs shown) and rating (4.2 vs 3.8). On price, in-app purchases, monetization model 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 3.8. That said, the two scores are not equally well evidenced: Fourth Grade Learning Games has 13K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 48% of Fourth Grade Learning Games's written reviews are positive against 100% of Math Gremlin's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Fourth Grade Learning Games ships an update every 4 months, Math Gremlin every 2 months. The most recent releases landed on October 16, 2026 and September 28, 2026 respectively.
