Gen cert, Sonic Mule, iPhone ***

Fancy yourself as a Rachel? How about a bit of a Mercedes or Kurt? Fans of the TV show Gleeshould get to the App Store quick smart. Sonic Mule has unleashed an app dedicated to the all-singing series that puts you at the heart of Glee. The scariest part of this app is that to really get the most out of the experience, you have to join in. Yes, that's right – sing, upload and let the rest of the Gleeworld witness your efforts. You can also listen back to others' efforts so the humiliation is evenly shared.

Build up fans (gleeks, for the uninitiated), connect with people through Facebook, try some songs out for free – Rehab, Somebody to Loveand You Keep Me Hanging On– and pay for the rest from the hit show.

Best thing? It features autotune. So even if you aren’t the best singer in the world, you can at least hold a note thanks to the technology that some rich recording artists have come to rely on. Who wouldn’t give it a shot?
