Locaii's a location-based check-in app that goes beyond saying "I'm here" in that it actually encourages conversation amongst proximate users; it was designed and self-funded by a Dallas-based, Rice- and UTD-educated physicist, who was Niels Bohr'd to death with people burrowing into their iPhones and forgetting their surroundings. The gist:
- Find friends via Facebook, or via the app itself, which lets you easily invite, say, that dude in the corner using Locaii
- Divide contacts into "Trusted Friends" -- who get to see everything -- and "Friends" (a designation quickly upgradable if a "Friend" wants to look at your iPhone)
- Pick people and locations (bars, restos, sports venues) to follow
- Hit someplace and check in, either publicly or anonymously
- Start a public convo about the location by posting a photo or observation ("Inspired crowd tonight"), or creating a poll w/ custom response options; e.g., "Should I sex this waitress?" could inspire "No, you'll get VD", "Yes, you'll get VD", or "Don't you mean could I sex this waitress?"
There's also a game element, called Identity, where going to the same few places'll get you labeled "Neighborhood Mogul"; adding tons of friends & followed locales makes you a "Neighborhood Pirate"; app-talking to very few folks makes you a "Conversational Ninja"; and yapping at a lot of folks makes you a "Conversational Rock Star" -- if Doc Brown had been one of those, maybe he'd have gotten a lot more Hills and Valleys.
