(KUTV) Steve Shillingford has received a lot of feedback from Sudo users.
He says there are about two million Sudo identities being used.
And it's not just tech fans using the app, but the average, "everday" person who want to protect their personal information.
"They literally don't care about the technology," Shillingford said. "The psychology of this interaction is probably more important than actually the underlying tech."
Many women like to use the app because it allows them to compartmentalize their lives.
"There's an element of safety there that's really, really important." Shillingford said.
