Verdict
The clearest difference is review sentiment: CMDb2.0 at 100% against 知乎's 16%. CMDb2.0 also leads on rating (5.0 vs 4.5) and ads (none vs shown). 知乎's advantage is ratings volume (26K vs 2) and chart position (#121 vs unranked). On price, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. 知乎 sells 13 in-app purchases, starting at $2.99 per month and CMDb2.0 sells 6 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
CMDb2.0 holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: 知乎 has 26K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 16% of 知乎's written reviews are positive against 100% of CMDb2.0's.
知乎 ships an update weekly, CMDb2.0 every 2 weeks. The most recent releases landed on September 28, 2026 and September 7, 2026 respectively.
