# Physics vs DEV

The clearest difference is price: DEV at Free against Physics's $4.99. DEV also leads on iOS requirement (15.0 vs 17.6). On update cadence, ads, in-app purchases and device support there is nothing between them.

DEV is free to download; Physics costs $4.99 up front. Physics sells 2 in-app purchases, starting at $4.99 per month and DEV sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
