Dear Side books Team, I am well satisfied with your APP especially with your policy decision of non collection of user data. I would like to give you a point to consider to be better than your peers. At present there is 'background color' changing option alone, try to Add 'page color' changing option with colors such as SEPIA, BLACK, etc...for nighttime users....expecting an update ASAP...

This has been default book reading app since 2013. Is one of the best e-readers that I found page animation. Also for people who are having trouble comic books archived with zip change the file extension from ".zip" to ".cbz" ("CBZ" which means "Comic Book Zip" and "CBR" which means "Comic Book RAR" files are the most common extension use for comic book scans). The issue of files with ".zip" becoming corrupt happened to me on my old iPhone 5.

★★★★★ 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.

Changing review, for months the app crashes when opening a second PDF. No response and no solution in site. Love the app, but it's dead.

★★☆☆☆ gob · Dec 23, 2023

Whenever I tried opening a PDF through my files to this app, it would copy it as a new one in the app which is fine for the first time but repeating the same process with opening the same PDF would make a SECOND copy or (a new copy again) rather than opening the first PDF in the app which led to multiple pdfs of 1 PDF in the app, I don't know what caused this issue bcz it wasn't like this at first, and it doesn't have a great searching and organizing system, looking forward to a better version!

★☆☆☆☆ 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!

★☆☆☆☆ Teacher · Oct 28, 2025

❌ 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
