Micello, Inc. announced an app at this week’s Demo09 conference that will give you a Google Maps-type experience for indoor settings.

On Micello’s website, they explain:

Millions of people today use Google Maps to get to their destination. Micello goes one step further by extending a map inside locations, such as  convention centers, shopping malls, college campuses, airports, and theme parks. Micello brings any location alive on a mobile phone by providing a navigatable map and a rich set of interactive services in the context of time and place. Micello creates communities for these places, providing you highly relevant information on your mobile device.

Frankly I think this is a no-duh application. Why hasn’t this come out sooner? In fact, a time or two I’ve wondered to myself if there was an app out there for something like this, and now I’m wishing I’d done more research and made the app myself.

Check out the video below:

There will be a heck of a lot of practical use for an app like this, but my only concern is that at launch “We will have over 100 maps of the bay area when we release the application in few weeks,” according to Micello’s press release. “We add about 10 maps a day and are scaling to accelerate that. We will add a region at a time.” So it will be a while before Micello is truly comprehensive.

“The maps today bring you to the door. We take you inside the place. It’s the last mile, the unchartered territory. We are building the foundation for indoor location based services and creating an eco-system similar to what’s happening in the outdoor space,” said Ankit Agarwal, Founder and CEO of Micello. “Micello is really all about people, places and events at indoor locations. What’s happening here and who is here now,” he added.

At launch, Micello will be free. But there was no word on when it will be ready.
