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.

Verdict

The call

The clearest difference is review sentiment: TTReader at 100% against i2Reader Cloud's 48%. TTReader also leads on rating (4.8 vs 4.1) and update cadence (every 3 weeks vs every 3 months). i2Reader Cloud's advantage is ads (none vs shown) and ratings volume (74 vs 10). On price, in-app purchases, monetization model and device support there is nothing between them.
