# Physics Formulas vs PhET Simulations

The clearest difference is rating: Physics Formulas at 5.0 against PhET Simulations's 4.5. PhET Simulations's advantage is ratings volume (49 vs 1) and review sentiment (66% vs 50%). On price, update cadence, ads and in-app purchases there is nothing between them.

Physics Formulas costs $0.99 and PhET Simulations $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Physics Formulas holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: PhET Simulations has 49 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Physics Formulas's written reviews are positive against 66% of PhET Simulations's, so the app with the better star average is not the one people write more warmly about.

Physics Formulas ships an update every 7 months, PhET Simulations every 14 months. Both last shipped on October 2, 2026.
