MORE than 150,000 Irish people are using the online 'hook-up' service Tinder.
The new research has identified of Irish online dating habits.
Tinder is an app that allows people to swipe through photographs of potential matches in a form of online speed-dating.
Individuals sign up and use personal profile images from their Facebook library.
Swiping right on a profile indicates interest, whereas swiping left indicates no interest.
When two people swipe right on each others' profiles, the app allows them to communicate with each other.
However, the chances of meeting a match on the casual dating service are only one in a hundred.
Of the one billion swipes recorded every day, just 12 million matches are made, according to the company.
Those who use the app are more likely to be under 25, say researchers for Ipsos MRBI, which counted the number of Irish people who say they use Tinder.
Contrary to some reports claiming it is largely being used by women, Irish Tinder users are balanced roughly equally between the genders.
Whereas the creator of the app, Sean Rad, has said he regards it as a networking and communications service, it has gained a reputation for being a conduit for casual sex across Europe and the US.
Twenty-somethings, which are the most active users, resort to it in bars and nightclubs as a way of meeting people on the spot.
The service has an estimated 50 million monthly "active users" located mainly in western countries, compared with 864 million "active" Facebook users and 300 million "active" Twitter users.
Those who use the app quickly become addicted to it,with the average Tinder user spending between an hour and 90 minutes using the app every day, logging in 11 times.
That rivals the likes of Facebook or Twitter.
The figures also show that men are much less fussy than women when it comes to identifying a match.
Men are three times as likely (46pc) to swipe 'like' on a woman's profile as women are (14pc) on a man's profile.
