The app itself is pretty simple, beautiful and slick. You can check out various featured collections, including a behind-the-scenes look at the making of Planet Earth II, or browse the mammoth archive in its entirety. You can filter clips by species, behavior and habitat, build your own collections and share your favorite moments. As you may have guessed from the size of the library, all clips are streamed, so best to stick to WiFi if you don't want to burn your data allowance hunting around for the app-exclusive easter egg clips staring Attenborough himself.
