Detroit Labs, which produces Apps for mobile and the web, has launched a free iPhone application called Landmarked Detroit that lets users "check in at different Motor City points of interest and flip through morsels of background information," according to MLive.

There's historic info on Cobo Center, where Martin Luther King delivered his famous 1963 "I Have A Dream Speech" after the Detroit Freedom March and several weeks before King made that line famous on the Mall in Washington.

The app promotes itself by saying: "Look at the map of significant landmarks that are all walking distance in downtown Detroit. Once you physically travel to a landmark you can unlock information about Detroit's past, present and future. Each landmark has 3-6 cards of detail. Each card is a one-minute read to give a little more insight about what makes Detroit unique."

The app features 20 landmarks in downtown Detroit.

Will McDowell, a business analyst at Detroit Labs, came up with the idea last summer as a new way to connect with his city, and said he hopes the app allows others do the same.

“There’s all these unique facts,” McDowell said. “Like Compuware has the world’s largest indoor waterfall or Martin Luther first said ‘I have a dream’ in Cobo Hall. … It’s all about discovering Detroit’s stories and it’s an easy way to learn little facts that make Detroit special.”
