The app will allow fans to back their favourite acts once the programme reaches the live shows stage.
Those with tablets and smartphones running Apple's iOS and Google's Android software can download the free app.
Viewers will be able to cast up to five votes whenever the polls are open and they can back one contestant or a combination.
Ann Cook, of ITV, said: "Having successfully launched in-app voting for The X Factor last year, we know there's a growing appetite for viewers to engage with the show via a digital platform.
"The new initiative to offer in-app voting for free centres around our ambition to give viewers new and exciting ways to interact with our shows, and explore how a mixed economy of free and paid voting drives interactive behaviour."
The X Factor returns to UTV on Saturday and Sunday from 8pm.
