# 초동수사 vs POOLS™

The clearest difference is rating: POOLS™ at 4.5 against 초동수사's 3.3. POOLS™ also leads on ads (none vs shown) and ratings volume (1.6K vs 3). 초동수사's advantage is update cadence (weekly vs every 2 months) and review sentiment (92% vs 79%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. 초동수사 sells 7 one-off in-app purchases and POOLS™ sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

POOLS™ holds the better App Store score, 4.5 against 3.3. That said, the two scores are not equally well evidenced: POOLS™ has 1.6K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 92% of 초동수사's written reviews are positive against 79% of POOLS™'s, so the app with the better star average is not the one people write more warmly about.

초동수사 ships an update weekly, POOLS™ every 2 months. Both last shipped on September 26, 2026.
