Apptivism runs through Facebook Messenger and is being trialled in Jersey until Sunday. It has been designed to give people a chance to share their opinions without having to attend a meeting.
Islanders can click on a link to join an interactive conversation, which takes around three minutes. They can share their views, compare their answers to how other users have responded and leave any comments they might have on specific issues.
And the app has been praised by author, broadcaster and former Downing Street press secretary Alastair Campbell, who tweeted: 'Good to see launch of apptivism. Real potential to increase people's voices.'
Apptivism co-founder Alex Tupper said: 'We hope to reach over 5,000 people in the first live test of our new chat software.
'The results of the anonymous pilot will be presented to the States and if user feedback is positive, the software might become a regular feature of government public consultation.'
Digital Jersey chief executive Tony Moretta added that Jersey provided a 'dynamic environment to test new technology and to help residents express their views'.
Islanders can give their views by searching apptivism.je on Facebook.
Meanwhile, former Chief Minister Frank Walker has been appointed as the new chairman of Digital Jersey.
Mr Walker will take over at the end of the month when the current chairman, Paul Masterton, steps down.
He is a former managing director of the Guiton Group and currently serves on a number of company boards, including that of Andium Homes. He also chaired the initial working group which ultimately led to Digital Jersey being set up.
Mr Moretta said: 'At a time when Jersey is facing many challenges which will impact the digital economy, from skills shortages, to e-gov and the potential changes that Brexit will bring, Frank's political and business experience will be invaluable to us.'
