# Physics AI vs Calculus Solver

The clearest difference is monetization model: Calculus Solver at free with in-app purchases against Physics AI's subscription. Calculus Solver also leads on ads (none vs shown) and iOS requirement (14.0.0 vs 16.0). Physics AI's advantage is update cadence (fortnightly vs every 21 months) and review sentiment (25% vs 0%). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Physics AI sells 2 in-app purchases, starting at $5.99 per 7 days and Calculus Solver sells 4 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Physics AI holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Physics AI has 287 ratings behind it against 30, so its average is the more settled of the two. Written reviews point the same way: 25% of Physics AI's written reviews are positive against 0% of Calculus Solver's.

Physics AI ships an update fortnightly, Calculus Solver every 21 months. The most recent releases landed on October 10, 2026 and October 13, 2026 respectively.
