GuardianWitness launched as an iOS and Android app last April to source UGC from readers and was developed using n0tice, the Guardian's mobile publishing platform.
When the platform launched, Joanna Geary, social and communities editor for the Guardian at the time, told Journalism.co.uk: "It's an essential part of our future and we believe that our ability to collaborate and do open journalism is essential in the digital age. That is journalism."
