I use Smash - Comic and Manga Reader. It's also optimized for the iPad 3 Retina Display. Very nicely laid out and very enjoyable to read your comics on.
Here's some screenies. It's $3.99 in the iStore.
I found there video displaying the app. Check it out.
I started using 'Comics' by ComiXology a few days ago and like it better than Smash Comic and Manga Reader. The In-Store feature is second to none. It's also optimized for the Retina Display on the iPad 3.
The only drawback to this is it's just like the Marvel comic app, there's a store to purchase and download your favorite comics but it does not support app syncing through iTunes. In other words, if you have a whole bunch of .cbr files (which are comic files) you can't load them into this app.
The other app that I used called 'Smash' comic and manga reader did support .cbr files along with a few other formats as well. So it seems that if you want to sync your own comics you will need one type of app and if you want to download and pay for comics within the app itself you would need a separate app all together.
This evening I did some investigating on which apps are the best comic viewers that support app syncing and came across 'Comic Zeal' which is very nice, has some of the best ratings for comic viewers in the app store and has Retina Display support. It seems to be even better than 'Smash' comics and manga reader. I'm going to try it out and report back later what I think.
I don't know if this is the same thing, but I had some downloaded to my PSPGO and they were excellent. The best ones were Marvel Zombies, they should defo make this series into a movie franchise!
I have the comiXology app as well and I love it to death. Like you said, though, it's unfortunate that you can't upload comics from other sources to it. I'd like to upload some issues of comic books that I know will never make it on to the comiXology release schedule (or at least not sometime soon) such Generation X and Darkhawk. This Comic Zeal sounds intriguing. So it'll show CBR files on Apple devices then, correct? I may have to download that app.
Forget what I said about Comic Zeal, I have officially tried all the comic file apps in the iStore and the best of the best is by far ComicGlass. It not only looks better but is better. It also has more settings than you can shake a stick at for customization. It renders the graphics in ComicGlass faster than Comic Zeal does too. Too bad I can't get my money back for the ones I didn't like. Anyways here are some screen captures of it too.
I have been using the comiXology app as well on my Kindle Fire and the comics look great! I don't read them as much as I wish. Anyone suggest any good reads? I'm open to anything
If you want superheroes, the best book out there today is Invincible. As for the "big 2", I'd go with Wonder Woman, Batman or Justice League from DC and Daredevil, Ultimate Comics: Spider-Man or Wolverine and the X-Men from Marvel.
If you want anything but superheroes, I highly recommend The Walking Dead, Morning Glories, Saga, Saucer Country, Mind the Gap, Atomic Robo and my absolute favourite comic series of all time (even though it currently unavailable through comiXology), Y: The Last Man.
Just checked out Invincible and Atomic Robo. Both are excellent! Thanlks a lot
