# KxCoding vs 코딩챌린지

The clearest difference is update cadence: 코딩챌린지 at every 6 days against KxCoding's every 3 months. 코딩챌린지 also leads on iOS requirement (11.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. KxCoding sells 8 in-app purchases, starting at $49.99 per month and 코딩챌린지 sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

KxCoding ships an update every 3 months, 코딩챌린지 every 6 days. The most recent releases landed on September 20, 2026 and May 16, 2026 respectively.
