# 사락 vs 책기록

The clearest difference is update cadence: 책기록 at daily against 사락's every 2 months. 사락's advantage is device support (3 vs 1) and iOS requirement (15.6 vs 17.0). On price, ads and in-app purchases there is nothing between them.

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

사락 ships an update every 2 months, 책기록 daily. The most recent releases landed on October 20, 2026 and October 7, 2026 respectively.
