What's a good Android app for catching up on my manga when I'm backpacking through South America and have dodgy internet?

Honestly, Mango has been a proper useful app for me. As a travel blogger, I'm constantly on the move, and reliable internet is a luxury, not a guarantee, especially when I'm off the beaten track. I was recently trekking in Peru, and Mango allowed me to download a load of manga before I left the hostel. It meant I could chill out in the evenings without stressing about finding a decent connection or eating up my roaming data. The fact that it's specifically for Spanish manga is also grand because I'm trying to brush up on my Spanish. It works a treat, and it's definitely sorted my manga needs while I'm travelling. It's rated really well too, so it's not just me who thinks so!
