FAQ
Can this app edit the body text of chapters or convert TXT/PDF files into EPUB?
No. This app is dedicated to EPUB cover design, metadata editing, reading direction layout, and repackaging. It does not edit chapter text or convert document formats.
How does local Wi-Fi transfer work?
As long as your Apple device and e-reader (Kindle, Kobo, BOOX, etc.) are connected to the same Wi-Fi network, start the transfer mode and scan the QR code or enter the provided URL in the reader's built-in browser to download your EPUB.
Will adding high-resolution covers blow up the EPUB file size?
No. The built-in smart compression automatically optimizes the image file size while keeping visual details razor-sharp on high-DPI reader screens.

Actually Works🤯
Most of these types of apps are complete garbage, this is not the case. Amazing app, very fast, and a real developer that responds to users. Phenomenal work!

Almost perfect!
This is very convenient to have on the phone, I have a few suggestions, since this is a new app, maybe the dev would consider.
1) Would be great to be able to add the series name & volume in the metadata of the epub.
2) When adding an image from the camera roll, it would be great to be able to write the name of the book with whatever fonts are installed in the iPhone & the option to change…— MalloryKnoxxxx, United States, · See reviews on the App Store
