# App CDMX vs FreeBuf知识大陆

The clearest difference is review sentiment: FreeBuf知识大陆 at 100% against App CDMX's 44%. App CDMX's advantage is rating (4.8 vs 4.0) and in-app purchases (none vs 12). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. FreeBuf知识大陆 sells 12 one-off in-app purchases. App CDMX asks for nothing beyond the download.

App CDMX holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: App CDMX has 462 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 44% of App CDMX's written reviews are positive against 100% of FreeBuf知识大陆's, so the app with the better star average is not the one people write more warmly about.

App CDMX ships an update weekly, FreeBuf知识大陆 every 8 days. The most recent releases landed on September 22, 2026 and September 23, 2026 respectively.
