# CSDN vs Dev Utils

CSDN and Dev Utils both sit at 4.7 stars, but that hides the real split: 92% of Dev Utils's written reviews are positive against 45% of CSDN's. Dev Utils also leads on in-app purchases (none vs 16) and ads (none vs shown). CSDN's advantage is update cadence (weekly vs every 4 months) and ratings volume (1.7K vs 101). On price, rating, device support and iOS requirement there is nothing between them.

Both are free to download. CSDN sells 15 in-app purchases, starting at $12.99 per month. Dev Utils asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.7 for CSDN against 4.7 for Dev Utils. That said, the two scores are not equally well evidenced: CSDN has 1.7K ratings behind it against 101, so its average is the more settled of the two. Written reviews are what separate them: 45% of CSDN's written reviews are positive against 92% of Dev Utils's.
