# 心知岛 vs 自传

The clearest difference is iOS requirement: 心知岛 at 9.0 against 自传's 11.0. On price and in-app purchases there is nothing between them.

Both are free to download. 心知岛 sells 10 one-off in-app purchases and 自传 sells 1 in-app purchase, starting at $2.49 per month. Whichever you choose, the download price is not the number that matters.
