Verdict
The clearest difference is ads: 小律 at none against 须臾's shown. 小律 also leads on rating (5.0 vs 4.7) and review sentiment (97% vs 84%). 须臾's advantage is ratings volume (456 vs 4) and iOS requirement (14.0 vs 16.1). On price, update cadence, in-app purchases and monetization model 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. 须臾 sells 1 one-off in-app purchase and 小律 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
小律 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: 须臾 has 456 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 84% of 须臾's written reviews are positive against 97% of 小律's.
须臾 ships an update every 3 days, 小律 every 4 days. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
