# 직상 vs 전자문제집 CBT

The clearest difference is ads: 전자문제집 CBT at none against 직상's shown. 전자문제집 CBT also leads on update cadence (daily vs every 9 days). 직상's advantage is iOS requirement (15.1 vs 18.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. 직상 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.

직상 ships an update every 9 days, 전자문제집 CBT daily. The most recent releases landed on September 23, 2026 and September 17, 2026 respectively.
