# 中英 vs 投屏助手

The clearest difference is iOS requirement: 中英 at 7.0 against 投屏助手's 13.0. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. 中英 sells 2 one-off in-app purchases and 投屏助手 sells 6 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.
