The Yes Equality group, which is campaigning for a Yes vote in the same-sex marriage referendum, has launched a free Yes Equality app to support its campaign.

Brian Sheehan, co-director of Yes Equality, called on people to take a “selfie for Yes” through the app and share it across social media.

“More than any other referendum in Ireland, social media has played a huge role in engaging new and younger voters. So far over 130,000 [people] have uploaded Yes Equality ‘twibbons’ [the Twibbon website enables users to increase awareness of campaigns] on Facebook and Twitter. Our register-to-vote appeal, which was driven primarily by social media, resulted in approximately 40,000 new voters registering.”

He said the new app was developed by a group of Yes Equality volunteers from the Irish tech community.
