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 am still currently using Tachiyomi (Android only) bc it still works, but the dev dropped developing it bc of lawsuits. There are forks of it as well
You can backup and import everything into mihon very easily. Including sources.
