iPhone/iPad: Try the first 20 pages per book free. All pages require a one-time in-app purchase. No monthly fees. For archives, PDFs and image folders.
Manage your own files and ebook metadata from ebookjapan, DMM, Kindle, BOOK WALKER, Rakuten Kobo and BookLive. Review before adding; prevent duplicates and preserve existing covers. Resume interrupted updates or run a full recheck.
New in-app online entries: Kobo (kobo.com), verified with a free book in a Rakuten ID-linked Japan/English library; Kindle (Amazon.com), verified with a free book. Both were tested through import, re-import and official reader text display. Other countries, including UK, and large/multi-page overseas shelves are unverified. New overseas entries exclude Safari Sharing, extensions and general saved HTML. Keep the login screen/text across app switches; use standard Paste. Shortcuts can open/search the shelf and be disabled in settings. Spine recognition, Japanese Siri AI and Google Play Books are deferred.
Use cover or list views, search/filter tags, add whole-book notes and organize series across stores, including manual merge/separation. Each purchase retains its own reading link. Send candidates from supported shelves displayed in Safari using the share sheet.
Japanese page OCR runs on-device. Use a correctly read ISBN to request NDL title-correction candidates and compare them with existing metadata. The replacement title starts unselected; only selected fields are staged in the editor, and existing metadata changes only when you save. Search terms/ISBNs are sent to NDL; ISBN cover requests use openBD.
Universal purchase scope
The universal unlock removes reading limits on Mac, iPhone and iPad with the same Apple Account. It does not add another OS's exclusive features. The iOS unlock covers iPhone/iPad; adding Mac requires an active iOS unlock plus Upgrade to universal. Universal and legacy full-reading purchases can be restored.
Mac Creator Tools (saving corrected images, batch export, eyedropper, etc.) is a separate purchase, not included in the reading unlock; it does not unlock reading by itself. Direct licenses, books, external-service fees and DRM removal are not included. Restoring purchases does not copy book files.

Piktoo Studio is an independent developer. Contact support@piktoo.com in English or Japanese. We reply in turn.
Privacy
No Emaki account, ads, usage analytics, or tracking. Reading history and connection details are stored on your device. When Sync Across Devices is on, viewing history, favorites, and bookmarks are stored in your iCloud and are not sent to the developer's servers. Komga integration syncs reading progress to the server you specify. Purchases and restoration use Apple In-App Purchase.
Online shelves open provider links without importing book files or bypassing DRM.
About the screenshots
