# Physics Master vs Chemical Engineering+

The clearest difference is review sentiment: Physics Master at 50% against Chemical Engineering+'s 0%. Chemical Engineering+'s advantage is rating (3.0 vs 2.0) and ads (none vs shown). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

Both are free to download. Physics Master sells 11 in-app purchases, starting at $0.99 per month and Chemical Engineering+ sells 6 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Chemical Engineering+ holds the better App Store score, 3.0 against 2.0. Both are backed by a comparable volume of ratings — 1 and 2 respectively. Written reviews complicate that: 50% of Physics Master's written reviews are positive against 0% of Chemical Engineering+'s, so the app with the better star average is not the one people write more warmly about.

Physics Master ships an update every 6 weeks, Chemical Engineering+ every 2 months. The most recent releases landed on June 1, 2026 and June 3, 2026 respectively.
