GarageMate

GarageMate ($50) is compatible with all the major garage door openers. It comes with a simple Android or iPhone app. Suppose you’re going biking and you want to open the garage door and you don’t want to take your keys with you. You can just open up this app on your phone, press one button, and the garage door opens up. It’s just like magic. All you have to worry about is taking your phone, and it’s much more convenient.
