# Chemistry. Periodic table. AI vs Factorization training

The clearest difference is in-app purchases: Factorization training at none against Chemistry. Periodic table. AI's 12. Chemistry. Periodic table. AI's advantage is ratings volume (2.7K vs 1) and update cadence (every 2 weeks vs every 2 months). On price, rating, ads and iOS requirement 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. Factorization training asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Chemistry. Periodic table. AI against 5.0 for Factorization training. That said, the two scores are not equally well evidenced: Chemistry. Periodic table. AI has 2.7K ratings behind it against 1, so its average is the more settled of the two.

Chemistry. Periodic table. AI ships an update every 2 weeks, Factorization training every 2 months. The most recent releases landed on October 2, 2026 and September 20, 2026 respectively.
