# CurioSeed vs Mechanism

The clearest difference is iOS requirement: Mechanism at 16.0 against CurioSeed's 26.5. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. CurioSeed sells 1 one-off in-app purchase and Mechanism sells 1 in-app purchase, starting at $39.99 per year. Whichever you choose, the download price is not the number that matters.
