Comments on SideBooks - PDF&Comic viewer for Android
★★★★★Mirmir· Sep 15, 2024
If ur looking for a much more realistic ebook reader I recommend this one. But the devs should add a sound page flip for realism & search button for finding a specific page to make it simple. Since it focuses on the title of pages It should be either the page number or the title of that specific page. And also the tutorial should be translated into English for more understanding to new users. BUT overall it's a good app It really brings a realistic experience like ur actually reading a book.

Best comic books and PDF reader. U can easily categorize ur books and reach them and even add notes on the pages.

❌❌❌❌❌ ✘✘✘✘✘ DOES'NT OPEN AFTER UPDATE... APP TOTALLY USELESS...NEVER INSTALL, JUST WASTE OF TIME

❌ Still it crashes soon after it is opened and when it is scrolld up or down and try to open next group of books, it stops
★☆☆☆☆Danny Pressler· Nov 13, 2024
I used to love it! There was no better app to see all your comics lined up on a shelf. Now after the updates, it crashes before it even loads. I thought it was my tablet that I have used with it for years, so I got a brand-new tablet, just for this app, and I was EXTREMELY disappointed that it had the same result. I'll have to settle with different readers until (hopefully) this one gets fixed!
