Sidecastr social TV app is a tweet-timeshifter. Well, timeshiftr…

The problem with a lot of social TV apps is that you have to use them at a specific time. Zeebox is no use to you for Mad Men episodes if you’re time-shifting them a few hours or days after their initial airing.

Sidecastr is a US iPad app that aims to be more useful. If you’re timeshifting your TV viewing, it timeshifts the best tweets about that show too. And it then even timeshifts your own (timeshifted) tweets. It’s enough to make your head spin.

“Sidecastr lets you experience a moment by moment replay of the best of the social TV content stream, even when you’re watching later. And because Sidecastr’s storage and playback of the social stream remains alive indefinitely, you can even add new comments long after an episode first airs, which in turn reaches fans who are watching after you.”

For now it’s Twitter-focused, although Facebook features are apparently coming in the next update. Most definitely one to watch – not least for a battle royale to come in the US with Zeebox (on its way across the Atlantic as we speak), Shazam, GetGlue, Miso and others.
