One of the most enjoyable features of Alfred is its two-way audio. You can talk to whoever (or whatever) is in front of the camera, which is pretty hilarious if you're using it to keep an eye on your pets. Imagine shouting at your dog to stop barking, or talking to your cat to see if it responds!

Alfred also has a night vision mode, which is super useful if you want to keep an eye on things in low light. The app is also free, with optional in-app purchases, which is a pretty sweet deal.
