If you download the zip files, I'd recommend using a reader called Maru. It's an app by a Korean developer and iirc I had to dig kinda deep into the play store to find it (I tried a bunch of other comic reader apps that I didn't like), but I had a really easy and pleasant experience with it when I was reading Part 4 on my phone. I definitely recommend it!
