Peregrin

About

Peregrin is an ebook reading application focusing on the gpub ebook format. It is intended to be used on mobile devices as a "progressive web app" (PWA). If you have not already: you can install it from your mobile browser.

It imports and keeps your books in browser storage, for which there is a storage limit of 5–10MB (you can check your current usage on the settings page). You can read and add books fully offline (this application does not make requests other than for its own assets) and does not engage in any form of tracking.

Once you have added a book, tap its name and you will be taken to the reader page. Swipe left and right to navigate pages. Tap in the middle to bring up or close the menu bar (from which you can get metadata, navigate via the table of contents, or go back to your book list).

Enjoy some great books in a great format!
