Users will be able to send audio recordings of the 35-year-old actor's voice saying, the app's name or alternatives like 'Bueno, b-tch,' or 'I love you, b-tch', reported Time magazine.
The app, which is free in iTunes but offers in-app upgrades for purchase, was announced by Paul on Twitter on Friday.
"Yo Bitch! To everyone that has ever asked me to call them a bitch, here you go. It's an App Bitch! Happy Holidays," Paul tweeted.
