One of the first sports chat and fan interactive apps that we looked at here at Mobile Sports Report was one called SportStream, at the time the first app from a startup developer named Evri, which was also focusing on developing a real time content engine.

A lot has changed since last September when the app was first being shown around it had a football focus, was part of Evri and ran on both Android and Apple’s iOS platform. Well that has all changed. iPad users will love the new version of the app, currently it does not run on other platforms.

That is not too surprising considering how prevalent it is for tablet users to employ the device as a second screen while watching sports and a bigger display is easier to follow all of the chatter rather than using your phone.

Evri has set the app free to be a standalone development, although it is being led by Will Hunsinger, who led its development at Evri. It has its own funding from Vulcan Capital, also the venture capital firm that has funded Evri. Its first round of funding netted the company $3.5 million from Vulcan.

There is also a change in focus or possibly an expansion rather. Initially available as a SportStream Football as a place for fans to gather, follow scores and post comments, and that is no longer available, although it said that it will add that feature when the season begins. It currently handles the end of the NBA season as well as MLB. Hockey will also be added when the season starts up later this year.

You can add teams as favorites, and their games will be automatically added to a feature called game picker, but you can add any game that you wish to that feature as well. Tap the screen to enter into viewing the game info and check in to a game from the game picker list to participate in the conversation. Once checked in you can also post to twitter or Facebook.

The app does have one very nice feature that many will probably find very useful, that is the ability to filter out twitter streams and block specific users that are uninteresting, rude, or for whatever reason that you might want including simply data overload. The app uses a Facebook check in, which seems to me to be a bit limiting because many might not want to use that avenue to access it.

It seems that almost daily a new chat app is available; some like Bantr and Golf GameBook aimed at one specific category of fans and others including FanCru, GrabFan, JockTalk and PlayUp open to a broader base of fans and so more directly compete with SportsStream. However almost all of its rivals have come out on iPhone first, while SportStream selected the iPad first.

It is hard to predict how the interactive fan sites and apps will work out, but I suspect that the market is already reaching its limits as to how many apps it will support. However having a big cash funding round should help serve SportStream very well. Many other apps appear to be mostly self funded and as Facebook has shown, generating ad revenue from mobile is tough and so may take longer than some developers have.
