What's a good Android app for showing the blueprints on my tablet to the guys on the TV at the job site, without a bunch of wires?

Look, I needed something that could mirror my tablet screen to the TV in the trailer so I could show the crew the blueprints without huddling around my small screen or messing with HDMI cables. Cast to TV - Screen Mirroring, that's the one. The tutorial is total BS, don't even bother. But once you poke around, it's actually pretty simple. It just mirrors whatever's on your screen right to the TV. I've used it to show plans, videos, even just pictures. It's not perfect; sometimes it lags a bit, and it eats up the battery life pretty quick, so keep a charger handy. But for quick and dirty screen sharing, it gets the job done. I've dropped my tablet a couple times while using it, and the app still works, so that's a plus. Rain doesn't seem to bother it either, been using it outside a few times. Just remember to keep your device charged!
