Okay, so what's a good Android app for a live wallpaper that's actually reliable and won't drain my battery during a 12-hour shift?

Okay, so I've been trying out Sun & Moon Live Wallpapers, and honestly, it's been pretty good. I needed something that wasn't just a static picture to stare at all day, but also something that wouldn't kill my battery faster than I can say 'code blue.' This one changes the wallpaper based on the time of day, so you get sunrise, daytime, sunset, and nighttime scenes. It's like having a little window to the outside world when I'm stuck inside the clinic all day. What I really appreciate is that it's actually reliable. I've had it running for about six months, and it hasn't crashed once, which is a huge win in my book. I'm too tired to deal with glitchy apps after a long shift. Plus, it doesn't seem to be a huge battery hog, which is a major concern when I'm already running low on energy myself. It's a no-fuss approach to a live wallpaper, and sometimes, that's exactly what you need.
