I asked support on Twitter and they said the feature was coming soon so fingers crossed.
Looks like the new update adds filter by unread...I think...I never update apps right away when they do a massive overhaul.
Sooooo...remember when I said I'd talk about all the other comics apps? Me neither...but's it's 3AM and I just woke up...
New freebies!
Redeem the code HENCHPOD for
Henchmen #1 and
Henchmen: I, Henchbot #1 (Jamison Raymond and Ryan Howe)
FCBD 2015 Street Fighter: Super Combo Special
Death in Oaxaca #1 (Steve Lafler) (It's Lucha Libre and vampires?)
CBLDF Defender #2 The first one had a Neil Gaiman interview (still haven't read it) and other articles about censorship. This one has Eric Stephenson and other articles about censorship.
On to other apps. I'll start with
Comicsplus from the company who made the Archie app. I know nothing of this app since you can't actually sign up for an account. Found it a few months ago, tried a few times to sign up and got an error. Just tried again same thing. Looking at the website they do have different stuff than Comixology but I'd say if you do get signed up just grab free stuff. They can't even get signup right, no way they should get money.
Next is
Dark Horse. Full of Dark Horse and Dynamite comics. Dynamite is on Comixology and Dark Horse just joined up this week...BUT only graphic novels will be on Comixology. Dark Horse has a decent selection of free issues. The viewing is different than Comixology, try the free ones out to make sure you don't mind the differences.
2000AD Comics and Judge Dredd This is the British publisher. Fun fact, 2000AD was the first comics publisher to go digital. There's 4 free issues, I'm not sure if they rotate or not, so a periodic check in would be an idea. Plus you can buy Judge Dredd here, so that's a good reason to check it out. The viewing is much different than Comixology, try the free ones out to make sure you don't mind the amount of zooming required.
We could use a Wiki in this thread to put this kind of info in and maybe list the stuff that's always free and other stuff...
