App.net invites Windows Phone 7, Blackberry and HTML5 in from the cold

App.net, a website for helping distribute and monetize mobile apps, got started in 2010 with iOS and Android. Today it is expanding its support to three new app platforms: Windows Phone 7 (WP7), Blackberry and HTML5.

App.net is owned and operated by Mixed Media Labs, which was founded by Bryan Berg and Dalton Caldwell.

“A lot of the larger shops have apps on multiple platforms, and there are small developers that are experimenting with WP7,” says Caldwell, in an interview with VentureBeat. “Now that we have the core platform built, adding new platforms is straightforward for us to do. The larger vision of these new features is that we are getting to the point where we want a developer to be able to link to app.net/myapp [the URL of an application on App.net] and App.net will show the best version of their app for the device the user is on. The less end-users have to deal with the platform complexity and compatibility issues, and figuring out whether to use mobile website vs. app, the better.”

On his blog, Caldwell makes a minor apology to webOS, which wasn’t included in the new release.

“(sorry webOS),” he writes. I told you it was a minor apology.

App.net helps developers optimize their products’ online presence and provides tools to manage, monitor and promote their product. Using App.net, developers can create landing pages and widgets as well as monitor performance data.
