# CTA 말문제 vs 일백제

The clearest difference is ads: 일백제 at none against CTA 말문제's shown. CTA 말문제's advantage is update cadence (every 3 days vs every 9 days). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. CTA 말문제 sells 2 one-off in-app purchases and 일백제 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

CTA 말문제 ships an update every 3 days, 일백제 every 9 days. The most recent releases landed on October 28, 2026 and October 21, 2026 respectively.
