Guardian Angel watches over your Mac, locking it whenever you leave, and automatically unlocking it when you return. When you run Guardian Angel for the first time, you can choose how far you want to be from your computer before it locks, so whether you are at home or in the office you can tweak the range to your liking. Guardian Angel connects to your phone using bluetooth, so everything that you need is already in your computer and ready to go. Before Guardian Angel gets to work, you will be prompted to set a password to be used as a backup. That way, if you lose your phone, or it goes out of range, you can still get back into your computer the old fashioned way. If you want to change any settings, such as the locking range or your connected devices, the preferences button is still just a click away. We can't anticipate how everyone will use Guardian Angel. That's why we've made it possible for you to set your own custom behaviour by adding scripts and applications into the program's settings, allowing you to decide exactly what happens when your computer locks or unlocks. To give you a bit of an idea, we've included the ability to pause your iTunes on lock, so your music won't be left playing to an empty room, and you won't miss your favourite songs, but that's just the tip of the iceberg...
