Welcome to CNET Australia's App of the Day, where you can see some of the coolest, silliest and most useful apps in action.
If you haven't seen Wikitude yet, well, you should probably go check it out right now. It's an augmented-reality (AR) browser for your phone. What this means is that when you hold up your phone and view the world around you through its camera, you will see notes telling you various things about your location. It's great, for instance, for travel; say you're in the middle of Paris, Wikitude will show you Wikipedia articles about locations nearby, or you can search for ATMs, restaurants, user reviews and tweets. There's even a game that lets you pop bubbles floating by. If you go out on your own a lot, then Wikitude is going to be indispensible.
