# 読書管理ビブリア vs mekuru

The clearest difference is ads: mekuru at none against 読書管理ビブリア's shown. mekuru also leads on update cadence (every 3 days vs every 2 months) and rating (5.0 vs 4.8). 読書管理ビブリア's advantage is ratings volume (24 vs 1) and review sentiment (95% vs 84%). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. 読書管理ビブリア sells 1 in-app purchase, starting at $4.99 per month and mekuru sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

mekuru holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: 読書管理ビブリア has 24 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 95% of 読書管理ビブリア's written reviews are positive against 84% of mekuru's, so the app with the better star average is not the one people write more warmly about.

読書管理ビブリア ships an update every 2 months, mekuru every 3 days. Both last shipped on October 21, 2026.
