# Physics AI vs Physics AI

The clearest difference is update cadence: Physics AI at every 9 days against Physics AI's every 4 months. Physics AI also leads on iOS requirement (15.0 vs 18.6). On price, ads, 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 $3.99 per 7 days and Physics AI sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Physics AI ships an update every 4 months, Physics AI every 9 days. Both last shipped on October 25, 2026.
