# 프로 장기 vs 오목제로

The clearest difference is ads: 오목제로 at none against 프로 장기's shown. 오목제로 also leads on update cadence (fortnightly vs every 3 months) and iOS requirement (13.0 vs 15.6). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

프로 장기 ships an update every 3 months, 오목제로 fortnightly. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
