# Data Structures and Algorithms vs 考研政治

The clearest difference is iOS requirement: 考研政治 at 14.0 against Data Structures and Algorithms's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Data Structures and Algorithms sells 1 one-off in-app purchase and 考研政治 sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
