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

Verdict

The call

The clearest difference is update cadence: CHMate at every 4 weeks against i2Reader Cloud's every 3 months. i2Reader Cloud's advantage is ratings volume (74 vs 20) and iOS requirement (15.6 vs 26.0). On price, rating, review sentiment and ads there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. CHMate sells 1 one-off in-app purchase and i2Reader Cloud sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

i2Reader Cloud holds the better App Store score, 4.1 against 3.9. Both are backed by a comparable volume of ratings — 20 and 74 respectively. Written reviews complicate that: 55% of CHMate's written reviews are positive against 48% of i2Reader Cloud's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

CHMate ships an update every 4 weeks, i2Reader Cloud every 3 months. The most recent releases landed on October 4, 2026 and October 3, 2026 respectively.
