Greg Grunberg talks up Yowza and who has gaydar on 'Heroes'

"Heroes" mind-reader Greg Grunberg was pretty excited to talk to the Dish Rag about his new project.

No, not a new TV show. Not an indie flick. He developed a new app for the iPhone called Yowza.

But watch the video and he'll tell you all about it.

And he's pretty psyched about being in the L.A. Times in an article about his new invention.

Since he was at the 20th Annual GLAAD Awards on Saturday night, we tried to stay on topic. Amazingly, Greg also reveals who is gay on "Heroes" (no, not Sylar, in fact, not anyone) and who has gaydar.

"We should have a gay character on the show!" he says, "I should be gay on the show.... If anyone should have gaydar, it should be me!"
