# 知乎 vs 百度贴吧HD

The clearest difference is rating: 知乎 at 4.5 against 百度贴吧HD's 3.2. 知乎 also leads on update cadence (weekly vs every 2 months) and ratings volume (26K vs 562). 百度贴吧HD's advantage is in-app purchases (none vs 17) and ads (none vs shown). On price there is nothing between them.

Both are free to download. 知乎 sells 13 in-app purchases, starting at $2.99 per month. 百度贴吧HD asks for nothing beyond the download.

知乎 holds the better App Store score, 4.5 against 3.2. That said, the two scores are not equally well evidenced: 知乎 has 26K ratings behind it against 562, so its average is the more settled of the two. Written reviews complicate that: 16% of 知乎's written reviews are positive against 30% of 百度贴吧HD's, so the app with the better star average is not the one people write more warmly about.

知乎 ships an update weekly, 百度贴吧HD every 2 months. The most recent releases landed on October 22, 2026 and October 17, 2026 respectively.
