# Physics Formulas Lite vs Chemical Formulas Quiz

The clearest difference is ratings volume: Physics Formulas Lite at 60 against Chemical Formulas Quiz's 7. Chemical Formulas Quiz's advantage is iOS requirement (11 vs 15.1). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Physics Formulas Lite holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Physics Formulas Lite has 60 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 81% of Physics Formulas Lite's written reviews are positive against 89% of Chemical Formulas Quiz's, so the app with the better star average is not the one people write more warmly about.

Physics Formulas Lite ships an update every 4 months, Chemical Formulas Quiz every 3 months. The most recent releases landed on November 1, 2026 and November 8, 2026 respectively.
