# Chemistry. Periodic table. AI vs MathNotes

The clearest difference is rating: Chemistry. Periodic table. AI at 4.9 against MathNotes's 4.0. Chemistry. Periodic table. AI also leads on ratings volume (2.7K vs 3) and device support (6 vs 4). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Chemistry. Periodic table. AI sells 9 in-app purchases, starting at $1.99 per 7 days and MathNotes sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Chemistry. Periodic table. AI holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: Chemistry. Periodic table. AI has 2.7K ratings behind it against 3, so its average is the more settled of the two.

Chemistry. Periodic table. AI ships an update fortnightly, MathNotes every 2 weeks. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
