# 流迹 vs Second Brain

The clearest difference is device support: 流迹 at 3 against Second Brain's 1. 流迹 also leads on iOS requirement (14.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. 流迹 sells 2 in-app purchases, starting at $3.99 per month and Second Brain sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
