# 방학일기 vs 공책

The clearest difference is update cadence: 공책 at every 9 days against 방학일기's every 11 months. 방학일기's advantage is iOS requirement (13.0 vs 15.1). On price, ads, 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.

방학일기 ships an update every 11 months, 공책 every 9 days. The most recent releases landed on August 20, 2026 and September 19, 2026 respectively.
