# Vocabulary Builder by Learning vs Math AI

The clearest difference is rating: Vocabulary Builder by Learning at 4.7 against Math AI's 3.0. Vocabulary Builder by Learning also leads on ratings volume (513 vs 3) and device support (3 vs 1). Math AI's advantage is review sentiment (100% vs 67%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Vocabulary Builder by Learning sells 11 in-app purchases, starting at $2.99 per 7 days and Math AI sells 3 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Vocabulary Builder by Learning holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Vocabulary Builder by Learning has 513 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 67% of Vocabulary Builder by Learning's written reviews are positive against 100% of Math AI's, so the app with the better star average is not the one people write more warmly about.

Vocabulary Builder by Learning ships an update weekly, Math AI every 2 weeks. The most recent releases landed on September 25, 2026 and September 9, 2026 respectively.
