If you've ever asked a friend to call you during a date in case you need an excuse to get out of there . . . a new app called Tickle is automating the process. The app uses the iPhone's accelerometer to sense your awkwardness on a date.
It monitors things like fidgeting or shaking your leg. And if it senses enough, it generates a FAKE PHONE CALL you can answer and use to escape. The app is coming soon . . . you can sign up for a waiting list now.
