ReceptionRating · Positive reviews · Number of ratings

Chemistry. Periodic table. AI holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Chemistry. Periodic table. AI has 2.7K ratings behind it against 60, so its average is the more settled of the two. Written reviews complicate that: 84% of Chemistry. Periodic table. AI's written reviews are positive against 86% of Physics Formulas Lite's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Chemistry. Periodic table. AI ships an update every 2 weeks, Physics Formulas Lite every 4 months. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
