Great full featured ebook reader, very customizable. The only ebook reader that I really enjoy on iOS while using my ipad mini. The complaints about the advertisements or price of the pro version is understandable and probably could use some modification. If the developer was willing to adopt only one limitation for the free version instead of two it would be more palatable. Currently the free version not only has limited features, it also has advertisements. The ads help the developer generate some income so I'm not opposed to it. However adopting both models to encourage the move to pro is a bit iffy. On the good side, the move to pro is a modest fee imo. So I'm not complaining just analyzing. Personally I would like to see better image layout handling and an easy way to install fonts that some epubs require for proper look and layout. Otherwise i love this app.

This is one of my favorite reading apps (I'm still trying to settle on one I use 100% of the time, but this is the one I use most frequently). It has nice options and customizability. I wish it had more background color options and page turning options like Marvin, but overall it's a great app. The most common complaint I saw in the reviews was about ads running at the bottom of the screen, but I paid the couple of dollars to upgrade to the Pro version and there are no adds at all, so that seems like a stupid thing to complain about. I never use the free version of a reading app because the ads are annoying and take you out of the the reading experience. So if you get this app pay for the upgrade -- it's worth it (I got it on sale for $1.99 -- definitely money well spent and cheaper than other apps like Marvin).

And so far this app has done it. It took time to learn & become accustomed to, but the more I used it the better I liked it. I love that I can password lock either individual books or a whole folder. One thing that I do have trouble with is the fact that on my iPad I have the pro version I bought, but when I downloaded the app to my phone it looks like I'll have to pay again to get the pro version there. It seems to me that if I buy the pro version I should only have to pay for it once & have the ability to access it on all devices. I'm hoping this is just a glitch or I'm missing something. Aside from that I love the app & I'm thrilled to have found a replacement for iBooks.

This is the very best cbr app I've used on my iPhone & iPad. It's great for epubs too. You can pull content from your device, cloud storage, web libraries (Gutenberg, Google Books, etc.) & memory card storage devices like Leef iBridge. The only complaint I have is that the app doesn't auto zoom on comics when you turn the device landscape. That said, pinch in/out function works perfect, especially on smaller screens like iPhone. I don't usually buy "in-app purchases," but be sure to flip the four bucks for the Pro version. The ebook speed reading & summarization functions are totally awesome. Plus no more ads.

I am giving this app 5 stars, but I’m giving the app’s developer TWO STARS, because you all don’t answer emails and that is a negative as far as I am concerned. I finally figure it out myself. Now I would like to see that there can be someway to mark your notes with colors. That would be fantastic. Since I had to also take the time to keep trying until I could learn how to fine the different colors. Is there a way to underline in different colors lines. That would be grrrreeeaaat.
