My favorite reader. If you're the type of person who likes to tweak every preference setting, Challenger will satisfy. I found the number of settings overwhelming at first, but the built-in help file covers the basics. Free, ad free, and even has advanced features like syncing a folder from Google Drive or a Samba share. The home screen icons are a bit dated, design wise, but that's honestly my only real complaint and the author's energy obviously is better directed into the app's functionality. Not quite as intuitive as ComicRack, but donation driven, no pop-ups or nagging, and similarly feature rich. Plus, it's still actively being developed, unlike ComicRack. Outclasses even other paid comic readers.
Simple & works. Simply the best comic viewer out there without too much unnecessary gimmicks. Best feature of it? Truly free without ads. The UI can be updated though, to match newer android style (just personal opinion, still use it regardless)
My only complaint is the Google drive library access. It takes forever to sync. Looks like it downloads the file to get the info, then re-downloads the file when you want to read it. Downloading the file temporarily to read it I have no problem with, but the info sync takes forever. Wish there was a way to just point the library to my google drive folder it get the name and cover and not have t download every file and extract it. Makes it really really slow. I just want to stream the file from google drive. Hope this makes sense. :)
Works well on cbr. Displays a magnifier on epub that doesn't seem possible to turn off. Could use a goto page x function. By magnifier i mean a small rectangle on screen that displays a magnified portion of the text. Like a small floating magnifying glass. Something has changed though, it used to be on permanently now it shows if you touch the screen then disappears after a few seconds.
Image seems to be blur then actual it is. Did bimap scaling too but no improvement.. if I open pdf in other pdf reader it looks good but blur in challenger comics viewer.. function are good..
Perfect app, Add the following features and will be Devine!!! 1) Add bookmarks for ePub files. 2) An overview of all bookmarked books for us that we read two or three books simultaneously :) 3) Remove borders around ePub pages. 4) Real night mode for PDF files. Keep up the good work, God bless you.
