# 知乎 vs BYR BBS

The clearest difference is review sentiment: BYR BBS at 100% against 知乎's 16%. BYR BBS also leads on in-app purchases (none vs 10) and ads (none vs shown). 知乎's advantage is rating (4.5 vs 3.9) and ratings volume (26K vs 8). On price and device support there is nothing between them.

Both are free to download. 知乎 sells 8 in-app purchases, starting at $2.99 per month. BYR BBS asks for nothing beyond the download.

知乎 holds the better App Store score, 4.5 against 3.9. That said, the two scores are not equally well evidenced: 知乎 has 26K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 16% of 知乎's written reviews are positive against 100% of BYR BBS's, so the app with the better star average is not the one people write more warmly about.

知乎 ships an update weekly, BYR BBS every 5 weeks. The most recent releases landed on November 11, 2026 and November 2, 2026 respectively.
