# BookDiary vs YomuMark

The clearest difference is ads: BookDiary at none against YomuMark's shown. YomuMark's advantage is update cadence (every 4 days vs every 2 weeks) and iOS requirement (15.5 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. BookDiary sells 1 one-off in-app purchase and YomuMark sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

BookDiary ships an update every 2 weeks, YomuMark every 4 days. Both last shipped on October 31, 2026.
