Knock, Knock. Who’s There? These Apps Will Tell You.
The automated home is a future not too far away. We've already seen the launch of sensors that email us, plants that tweet at us, a smart thermostat, a coffee maker controlled by our phones, and so much more.
Our home entrances are getting an upgrade as well. Today, there are all kinds of gadgets and apps that help us provide a warmer welcome for our guests. Here are three of our favorites of late:
Pocket Doorbell is a magical app that turns your phone into a portable doorbell. It always knows where you are and which door to ring. When you arrive at your friend's house, just press a button and it will text or call your friend. It's also great for those of us in small apartments or homes with lousy doorbells.
It's only available for iPhone now, but there's a high probability the team will launch an Android version soon.
