Rebuilt for latest iPhone, iPad and iPod touch.
Ratings and Reviews
Excellent archive reader
I especially love it for picture archive files. The images aren't resized relative to each other, and it doesn't force images to fit into a single "page" like with another reader I use. Despite not having any updates for several iOS upgrades, it still works perfectly. Ads are small and unobtrusive. My go-to non-PDF reader app. (Not saying it can't read PDFs, just saying it handles non-PDFs the best of all the reader apps I've used.) There are problems reading nested archives, but that's an easy fix. Thanks, developer!
2 page landscape pdf view!
Finally an app with two page landscape view for viewing PDF's on IOS devices to include iPhone! AND ITS FREE??? It took me ~5 years to find this. It needs to be advertised better by Apple because there are countless other people I've seen on forums who are searching for this functionality. On top of everything you can go left to right or right to left. May God bless you (the developers of this app) and your family/progeny with endless blessings in this life and the next.
After seeing the age of ultron trailer I decided I wanted to re read my age of ultron without my laptop. Did a quick search to see which app was best for comics and this one did not disappoint! I was able to easily transfer age of ultron and other comics to both my iPad and iPhone 6. Minor lag on my iPad for age of ultron but it's a huge file so I won't complain. No lag on my 6. Anyone wondering which app to read comics, this is by far the best!!
With Family Sharing set up, up to six family members can use this app.
