# 책인아웃 vs 책기록

The clearest difference is update cadence: 책기록 at every 3 days against 책인아웃's every 8 days. 책인아웃's advantage is device support (3 vs 1) and iOS requirement (15.0 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.

책인아웃 ships an update every 8 days, 책기록 every 3 days. Both last shipped on October 29, 2026.
