# Physics Questions vs Physics AI

The clearest difference is update cadence: Physics Questions at every 4 days against Physics AI's fortnightly. Physics Questions also leads on iOS requirement (12.0 vs 16.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Physics Questions sells 9 one-off in-app purchases 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.

Physics Questions ships an update every 4 days, Physics AI fortnightly. The most recent releases landed on October 6, 2026 and October 10, 2026 respectively.
