Verdict

The call

The clearest difference is rating: CSDN at 4.7 against Storm Sniffer's 3.9. CSDN also leads on monetization model (free with in-app purchases vs subscription) and update cadence (weekly vs monthly). Storm Sniffer's advantage is ads (none vs shown) and review sentiment (76% vs 45%). On price, in-app purchases and device support there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. CSDN sells 15 in-app purchases, starting at $12.99 per month and Storm Sniffer sells 7 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

CSDN holds the better App Store score, 4.7 against 3.9. That said, the two scores are not equally well evidenced: CSDN has 1.7K ratings behind it against 120, so its average is the more settled of the two. Written reviews complicate that: 45% of CSDN's written reviews are positive against 76% of Storm Sniffer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

CSDN ships an update weekly, Storm Sniffer monthly. Both last shipped on October 22, 2026.
