Hi everyone. As the title says, I'm looking for a method to download manga on smartphone and then read it with a proper offline reader (any suggestion is appreciated).
Example: I've been reading comics (downloading them on the smartphone and then reading them with "Perfect Viewer" app) for years and I would start to read manga also with a similar solution.
I prefer to download them on the smartphone (and don't read it online) because I don't have always a decent Internet connection, and when I can access to that I use that to download as many comics I can.
Thanks in advance for all your help
EDIT: Thanks for your help, I'll try Mihon and Kotatsu
I've used Kotatsu. It's pretty good for all kinds of comics (not just Japanese manga).
You can download chapters while on WiFi and read without using data.
+1 for Kotatsu. It's a bit easy on the NSFW offerings, so, be careful with that in case this is important to the OP.
