Parents are said to have complained about live text competitions at the shows, reports The Sun.
The gigs - which already cost £37.50 - encourage attendees to text in to a competition to try and meet their favourite acts.
"I felt it was too much, given how much we'd already paid for tickets," one fan at a London O2 gig is quoted as saying.
"There were lots of young kids and you could see them texting when the offers came up."
Another concert-goer added: "It was outrageous - especially when it didn't even seem like much had been spent on the show. Thank goodness the finalists were so good."
James Arthur, Ella Henderson, Jahmene Douglas, Rylan Clark, Christopher Maloney, Union J and District3 perform on the tour, which continues until the end of February.
A tour spokesman said the 'Meet And Greet' competition offering fans a chance to meet the singers was "in no way compulsory".
Maloney recently denied that he was booed during a performance on the X Factor tour.
