Great App

I've been enjoying Shubook for years. It does everything I need it to do,and it does it simply. I had a problem with the latest version, but the developer replied right away with a fix, so I can say I'm enjoying it again very much.

Developer Response ,

You may open Book Settings and turn off System Screen Brightness to get back your old preferred setting. As for the "bad color themes" issue, we can't reproduce the bug. Can you send us a screenshot with your iPhone model and iOS version number? Thanks. In fact, we're doing an update in a few days. So you'd better email us soon in order to catch the next train. :-)

Forever User Suggests Improvements

I have used ShuBook almost from its inception, through each subsequent version, and right up to the current 2M version. I love its simplicity, the ability to download ePub & PDF books from any source, add tags, download book covers, sort by author, change fonts, change to nighttime reading, bookmark, etc. etc. It's never eaten or lost a single word, much less a book and I've read thousands and store thousands of books.

Why only 4 stars? It continues to lag behind all other major e-readers by lacking the ability to highlight text and to add your own notes for future reference. This is a major setback for me. I'm a voracious reader and getting older. My memory isn't what it once was. I hate that this otherwise perfect e-reader has an almost unforgivable flaw. I also use Kindle because of their proprietary e-books. I love the highlighting and note writing, but find it unwieldy as a library for all my e-books. Please, please add these indispensable features!!!

Why do I continue to use it over Marvin, which I also have? Marvin is a beautiful, full featured, overblown memory hog that only lets me upload from certain sources. ShuBooks 2M is a very lean memory user. That's a priority for me.

Best ereader out there!

I absolutely love Shubook. After Stanza was killed off I tried many apps that left me disappointed. Shubook is hands down the best and gets better with every update. The tagging system from Calibre now automatically sorts in Shubook. If you have a ton of books like I do this is a lifesaver.
