# PocketCAS vs Physics problem solver

The clearest difference is review sentiment: PocketCAS at 91% against Physics problem solver's 17%. PocketCAS also leads on rating (4.6 vs 1.0) and ads (none vs shown). Physics problem solver's advantage is in-app purchases (none vs 1) and iOS requirement (8.0 vs 18.0). On price and device support there is nothing between them.

Both are free to download. PocketCAS sells 1 one-off in-app purchase. Physics problem solver asks for nothing beyond the download.

PocketCAS holds the better App Store score, 4.6 against 1.0. That said, the two scores are not equally well evidenced: PocketCAS has 204 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 91% of PocketCAS's written reviews are positive against 17% of Physics problem solver's.

PocketCAS ships an update every 3 months, Physics problem solver every 6 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
