# 퀴즈플래닛 vs 초동수사

The clearest difference is ads: 퀴즈플래닛 at none against 초동수사's shown. 퀴즈플래닛 also leads on rating (3.5 vs 3.3) and iOS requirement (7.0 vs 15.0). On price, review sentiment, ratings volume and update cadence there is nothing between them.

Both are free to download. 퀴즈플래닛 sells 5 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.

퀴즈플래닛 holds the better App Store score, 3.5 against 3.3. Both are backed by a comparable volume of ratings — 2 and 3 respectively. Written reviews complicate that: 90% of 퀴즈플래닛'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.

퀴즈플래닛 ships an update every 9 days, 초동수사 weekly. Both last shipped on September 26, 2026.
