# Engineering English vs CurioSeed

The clearest difference is iOS requirement: Engineering English 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. Engineering English sells 2 in-app purchases, starting at $8.99 per month and CurioSeed sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
