Britain’s Got Talent viewers will be able to use the show’s smartphone app to vote on the contest from this weekend.
The new voting method will allow fans to have their say via iPhone, iPad or iPod Touch for the first time ever.
500,000 people have already downloaded the app and up to 130,000 fans per episode have used its "buzzer" to interact with the programme.
But the new voting mechanism will now allow viewers to support their favourite act directly from their Apple device.
When the voting window opens during the live shows, users will see a new button appear at the bottom of the app and will then be able to purchase a bundle of three votes for £1.49.
And from this weekend viewers will also be able to cast votes using Mobile Short Dial Codes, which allow UK mobile users to dial a short seven digit number and nominate favourite acts from their mobiles for a fixed price of 50p per vote.
Ann Cook, Director of Interactive ITV & Managing Director of ITL said: “We know that today's viewers like engaging and interacting with our biggest shows via new platforms and on many devices. Therefore it makes sense for us to explore introducing voting to the places where large numbers of viewers are already engaged.
“We’re really looking forward to seeing how audiences respond respond to both these two new voting platforms, alongside the existing landline platform, as Britain’s Got Talent moves into its exciting live final phase this weekend.”
