Read alone. Not alone—with quiet company for every page. mekuru is a reading room made for time with paper books. Small reader avatars settle into a warm study, and the gentle sign of a page turning lets you feel that someone else is reading too—without video, a microphone, or chat. WITH MEKURU, YOU CAN • Enter as a guest—no sign-up required • Join an open room and read quietly with others • Invite someone with a link and read together • Your reader turns its pages on its own — a faint paper sound is the only sign of presence that travels • Breaks and time away are sensed and shared softly, on their own • Keep your reading time and revisit it in your Time Shelf • Create an account to choose from six reader avatars and unlock book covers as you read • Become reading companions with the people you share a room with There are no DMs, likes, comments, follows, or rankings. mekuru is not about competing over pages. It is a place to let the time you spend with books accumulate quietly. In Korea, a trend called "text hip" has been spreading: enjoying the time spent reading, and sharing it. mekuru is a place to share that time — the middle of the reading itself — quietly, with someone else. OWNER (SUBSCRIPTION) The optional Owner plan is an auto-renewing subscription, billed monthly or yearly, that lets you furnish a room of your own and open it to your companions anytime. Registered accounts can try a one-time 14-day viewing first, no card required. In Japan the price is ¥580/month or ¥5,800/year; pricing for your region is always shown in the App Store before you confirm.

You can manage or cancel it anytime in your App Store account settings. Privacy Policy: https://www.mekuru.app/en/privacy Terms of Use: https://www.mekuru.app/en/terms

Verdict
The clearest difference is ads: mekuru at none against Cat's Library's shown. mekuru also leads on rating (5.0 vs 4.8). Cat's Library's advantage is ratings volume (43 vs 1). On price, review sentiment, update cadence and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Cat's Library sells 7 in-app purchases, 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: Cat's Library has 43 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 88% of Cat's Library'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.
Cat's Library ships an update every 4 days, mekuru every 3 days. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
