Verdict

The call

The clearest difference is price: STEMWerkz at Free against Marble Math's $3.99. STEMWerkz also leads on update cadence (fortnightly vs every 4 months) and rating (5.0 vs 4.7). Marble Math's advantage is in-app purchases (none vs 2) and ratings volume (1.3K vs 4). On ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

STEMWerkz holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Marble Math has 1.3K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 86% of Marble Math's written reviews are positive against 77% of STEMWerkz's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Marble Math ships an update every 4 months, STEMWerkz fortnightly. The most recent releases landed on September 29, 2026 and September 18, 2026 respectively.
