# 程序员面试 vs 知到.

The clearest difference is rating: 程序员面试 at 4.4 against 知到.'s 1.2. 程序员面试 also leads on review sentiment (33% vs 20%) and iOS requirement (10.0 vs 14.0). 知到.'s advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. 程序员面试 sells 1 one-off in-app purchase and 知到. sells 11 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
