# 모두의 자격증 vs 전자문제집 CBT

The clearest difference is ads: 전자문제집 CBT at none against 모두의 자격증's shown. 전자문제집 CBT also leads on update cadence (daily vs every 8 days). 모두의 자격증's advantage is iOS requirement (15.0 vs 18.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. 모두의 자격증 sells 1 one-off in-app purchase and 전자문제집 CBT sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

모두의 자격증 ships an update every 8 days, 전자문제집 CBT daily. Both last shipped on October 8, 2026.
