# Math Solver AI vs KnowNotes

The clearest difference is review sentiment: Math Solver AI at 67% against KnowNotes's 0%. KnowNotes's advantage is rating (4.5 vs 3.8) and update cadence (weekly vs every 2 months). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Math Solver AI sells 3 in-app purchases, starting at $4.99 per 7 days and KnowNotes sells 6 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

KnowNotes holds the better App Store score, 4.5 against 3.8. Both are backed by a comparable volume of ratings — 6 and 13 respectively. Written reviews complicate that: 67% of Math Solver AI's written reviews are positive against 0% of KnowNotes's, so the app with the better star average is not the one people write more warmly about.

Math Solver AI ships an update every 2 months, KnowNotes weekly. The most recent releases landed on September 18, 2026 and September 23, 2026 respectively.
