# 정보처리기사 vs 문어 CBT

The clearest difference is ads: 문어 CBT at none against 정보처리기사's shown. 문어 CBT also leads on update cadence (weekly vs every 3 months). 정보처리기사's advantage is review sentiment (86% vs 71%) and iOS requirement (13.0 vs 17.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. 정보처리기사 sells 2 one-off in-app purchases and 문어 CBT sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

정보처리기사 ships an update every 3 months, 문어 CBT weekly. The most recent releases landed on November 4, 2026 and November 10, 2026 respectively.
