# Chemistry. Periodic table. AI vs Physics Formulas

The clearest difference is price: Chemistry. Periodic table. AI at Free against Physics Formulas's $0.99. Chemistry. Periodic table. AI also leads on review sentiment (84% vs 50%) and update cadence (fortnightly vs every 7 months). Physics Formulas's advantage is in-app purchases (none vs 10) and ads (none vs shown). On rating there is nothing between them.

Chemistry. Periodic table. AI is free to download; Physics Formulas costs $0.99 up front. Chemistry. Periodic table. AI sells 7 in-app purchases, starting at $1.99 per 7 days. Physics Formulas 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 Physics Formulas. That said, the two scores are not equally well evidenced: Chemistry. Periodic table. AI has 2.8K ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 84% of Chemistry. Periodic table. AI's written reviews are positive against 50% of Physics Formulas's.

Chemistry. Periodic table. AI ships an update fortnightly, Physics Formulas every 7 months. The most recent releases landed on November 10, 2026 and November 6, 2026 respectively.
