Okay, so what's a good Android app for quickly viewing PDFs, especially when I need to check the design specs on the go? Gotta make sure those margins are pixel-perfect!

Okay, so for quickly viewing PDFs on Android, I've been using "PDF File Reader" by Dream Tools. It's not the *most* design-forward app I've ever seen, but the information architecture is pretty solid, and it doesn't overwhelm you with options. The basic functionality is there, which is key. It's great for quickly checking design specs that clients send over when I'm out and about. I mean, we all know how crucial it is to make sure those margins are pixel-perfect, right? Plus, the scrolling is smooth, which is a must. I haven't dug too deep into the accessibility features, but it seems to have basic support for text scaling, which is a plus. The interface is relatively intuitive, and it follows Fitts' Law pretty well, making it easy to select different pages. It's not going to win any design awards, but it's a functional, no-nonsense option for viewing PDFs on your phone.
