# MatheArena Classic vs AI Vocabulary Builder

MatheArena Classic and AI Vocabulary Builder are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. MatheArena Classic sells 5 in-app purchases, starting at $4.49 per month and AI Vocabulary Builder sells 4 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on November 6, 2026 and November 10, 2026 respectively.
