What's a decent Android app for loading up on books when I'm stuck on a job site with no internet?

Look, sometimes you're stuck waiting for concrete to dry or for the rain to let up, and there's no signal. طاقچه, that book app, lets you download books before you head out. So, you can actually read 'em offline. The interface is pretty straightforward, even with gloves on, which is a plus. Battery life ain't the greatest if you're reading all day, so bring a power bank. I've dropped my phone with this app running a couple of times, and it's still kicking, so it's actually rugged enough for the job site. The tutorial is useless, but once you figure it out, it gets the job done. No BS, just books when you need 'em, even when you're off the grid.
