# Mental Math Master vs AI Study & Flashcards · Recall

The clearest difference is in-app purchases: Mental Math Master at none against AI Study & Flashcards · Recall's 12. Mental Math Master also leads on review sentiment (100% vs 83%) and iOS requirement (13.2 vs 15.0). AI Study & Flashcards · Recall's advantage is ratings volume (250 vs 16) and device support (4 vs 2). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. AI Study & Flashcards · Recall sells 9 in-app purchases, starting at $3.99 per 7 days. Mental Math Master asks for nothing beyond the download.

AI Study & Flashcards · Recall holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: AI Study & Flashcards · Recall has 250 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 100% of Mental Math Master's written reviews are positive against 83% of AI Study & Flashcards · Recall's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on September 25, 2026 and October 11, 2026 respectively.
