The X Factor 2018 semi-final will feature free voting this year and here is just how to vote.
Once again for this year's X Factor live shows, you'll be able to vote for free using the show's official app.
You can vote by downloading the free iOS or Android version of The Official X Factor app on your smartphone or tablet
> Get the X Factor 2018 app for iOS devices: DOWNLOAD HERE
> Get the X Factor 2018 app for Android devices: DOWNLOAD HERE
Clear voting instructions appear within the app and you can vote a up to FIVE TIMES in each round of voting.
You can use your free votes on just one contestant or split them between any combination of contestants.
Or you could just not use them at all - but remember they don't rollover - so use them or lose them!
If you don't want to or can't use the app, you'll still be able to vote via phones or mobiles using the numbers given out in Saturday and Sunday night's live shows.
Lines for phone, mobile and online app votes will close at the same time as announced during the live show.
This weekend sees the semi-final live weekend as the remaining six contestants sing twice for the very first time this year.
In the Boys category are Anthony Russell, Brendan Murray and Dalton Andre Harris. In the Overs is Danny Tetley.
In the Girls category is down to just Scarlett Lee. Finally, in the Groups are duo Acacia and Aaliyah.
The results of the viewer vote will be revealed during the live show where there will be yet another double elimination.
The X Factor 2018 airs live this Saturday at 8PM and Sunday at 8PM on ITV. The final takes place live next weekend, December 1 and 2, taking place live form Wembley Arena.
