# Knowt vs MasteryAI

The clearest difference is review sentiment: MasteryAI at 100% against Knowt's 62%. MasteryAI also leads on rating (5.0 vs 4.7). Knowt's advantage is ratings volume (11K vs 3) and chart position (#111 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Knowt sells 9 in-app purchases, starting at $9.99 per 7 days and MasteryAI sells 3 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

MasteryAI holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Knowt has 11K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 62% of Knowt's written reviews are positive against 100% of MasteryAI's.

Knowt ships an update weekly, MasteryAI every 2 weeks. The most recent releases landed on November 9, 2026 and October 30, 2026 respectively.
