# 30일 vs 초동수사

The clearest difference is rating: 30일 at 4.4 against 초동수사's 3.3. 30일 also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). 초동수사's advantage is update cadence (weekly vs every 6 weeks) and review sentiment (92% vs 70%). On price, ratings volume, in-app purchases and device support there is nothing between them.

Both are free to download. 30일 sells 10 one-off in-app purchases and 초동수사 sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

30일 holds the better App Store score, 4.4 against 3.3. Both are backed by a comparable volume of ratings — 7 and 3 respectively. Written reviews complicate that: 70% of 30일's written reviews are positive against 92% of 초동수사's, so the app with the better star average is not the one people write more warmly about.

30일 ships an update every 6 weeks, 초동수사 weekly. The most recent releases landed on September 27, 2026 and September 26, 2026 respectively.
