Reading with comfort is a dream of any book lover! It’s more than 10 years already that my i2Reader has been making this dream come true. With each version of the app I add a bunch of new options and always try to keep the pleasure of reading a top priority. When putting books on digital shelves or turning over their 3D pages on any device (Mac, iPhone or iPad), you will always feel “I too Reader”* * - this is not a mistake :) Main features: • iCloud support: your library is synchronized in all your devices. You can start reading a book on iPhone and continue doing it on iPad or Mac! Everything from last the opened page, bookmarksо, highlighters to book metadata, including user's choice of a book cover, titles, genres, keywords, series etc. - is synchronized in each book; • Footnotes are displayed on the bottom of the page – like in real paper books! • Full support of 3D Touch: - in a library: to peek at a book info, press slightly on it; swipe up to bring up a context menu for this book; - when reading, you can assign 3D Touch to one of these options: Wikipedia or dictionaries. Press on a word and the assigned option will run right away, bypassing context menu. • Interactive guide to introduce features of the app; • Support of multitasking Side Over and Split View for iPad Pro, iPad Air or iPad mini; • Support Drag and Drop for iPad under iOS 11; • AutoScrolling – vertical text scrolling with adjustable by horizontal swipe speed; • Auto Turning – automatic page turning according to timer; • download books from Dropbox, Google Drive and Yandex disk as well. Google Drive now supports download of GDOC (Google Docs) files; • User's access: now all members of your family can read the same books not interfering with each other. Besides, the new feature enables you to highlight text fragments and comment on it, thus making up mini-chats in your own mini social/family networks :) • Review of reading statistics for both particular books and individual library users; • adjust brightness of the screen with a two-fingers vertical swipe; • finest configuration of a book layout for the most comfortable reading: everything like fonts, font size, colors, background is adjustable, including paragraph and line spacing; • i2Reader works with FB2 (also fb2.zip or fbz), EPUB (no DRM protection), MOBI, RTF, MS Word DOC/DOCX and PDF book formats; • different ways of page turning (including 3d page turning and vertical scroll); • voice/audio reading with the use of voice synthesizer; • easy selection and sorting of books based on various criteria - you won't get lost in your library and find your book in no time; • you can also create digital shelves which are also synchronized via iCloud; • support of starDict and XDXF dictionaries when reading; • Support of in-built iOS dictionaries; • support of Lingvo dictionaries when reading (if you have installed Lingvo app); • widget for notification center; • you can now share quotes to Facebook, twitter, Evernote or send then via email; • you can also download books from public OPDS libraries. All features in one simple and handy interface - now everything is at your fingertips! You are always welcome to share your opinion and suggestions to support@i2reader.net

Read full description

Organize your PDFs, set custom covers, and choose from several theme colors and icons, for a pleasant reading experience just the way you want it. • Create folders and folder groups to keep your PDFs organized however you prefer. Rename and rearrange things as the mood takes you. Name every single book and folder the same thing, if you really want to! (I don’t recommend doing that, but nonetheless, that’s the sort of awesome power that you wield if you use BookFolder.) • Set custom cover images for every book (or stick with a book’s default cover, of course). Your library will look the way that you want it to! (And the underlying files remain pristine, so if you begin to regret choosing a photo of your cat for every book in your collection, you can always restore the originals and no one will know. Except your cat, who is judging you now.) • Get wild on an iPad with split-screen multitasking support. Read two books at once (or the same book twice)! If that’s something that you want to do. • Swap between five theme colors, for an interface that works best for you. (Dark Mode support, too, of course!) • Choose from a dozen icons, from solid colors to subdued platinum to a retro rainbow look, to fit your mood and to ensure a harmonious home screen layout with your other apps. (I’m not the only one who arranges my icons by color and design… am I?) • You can use it to actually read the PDFs, too, of course. Mustn’t forget that part. • Plus bookmarks, searching, and table-of-contents support, as one would expect. • Also, it’s free, no in-app purchases, no tracking… just a nice PDF reader and library manager. I hope that you’ll enjoy it!
