# Chem AI vs Physics AI

Chem AI and Physics AI are too close to call on the numbers: across 10 compared parameters — price, rating, review sentiment and ratings volume among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Chem AI sells 15 in-app purchases, starting at $0.99 per 7 days and Physics AI sells 2 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.4 for Chem AI against 4.5 for Physics AI. Both are backed by a comparable volume of ratings — 822 and 287 respectively. Written reviews are what separate them: 20% of Chem AI's written reviews are positive against 25% of Physics AI's.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on October 20, 2026 and October 18, 2026 respectively.
