# csl. vs 小氣簿

The clearest difference is review sentiment: 小氣簿 at 100% against csl.'s 8%. 小氣簿 also leads on rating (5.0 vs 1.5) and update cadence (every 4 days vs every 3 weeks). csl.'s advantage is in-app purchases (none vs 2) and ratings volume (26 vs 1). On price, ads and device support there is nothing between them.

Both are free to download. 小氣簿 sells 2 in-app purchases, starting at $4.99 per month. csl. asks for nothing beyond the download.

小氣簿 holds the better App Store score, 5.0 against 1.5. That said, the two scores are not equally well evidenced: csl. has 26 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 8% of csl.'s written reviews are positive against 100% of 小氣簿's.

csl. ships an update every 3 weeks, 小氣簿 every 4 days. The most recent releases landed on November 1, 2026 and November 5, 2026 respectively.
