# Chemistry. Periodic table. AI vs Material Engineering

The clearest difference is ads: Material Engineering at none against Chemistry. Periodic table. AI's shown. Chemistry. Periodic table. AI's advantage is ratings volume (2.7K vs 2) and update cadence (fortnightly vs every 3 months). On price, rating, in-app purchases and monetization model 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 Material Engineering sells 6 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Chemistry. Periodic table. AI against 5.0 for Material Engineering. That said, the two scores are not equally well evidenced: Chemistry. Periodic table. AI has 2.7K ratings behind it against 2, so its average is the more settled of the two.

Chemistry. Periodic table. AI ships an update fortnightly, Material Engineering every 3 months. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
