e Harmony is another massive player, with 3 million users signed up.
But size isn’t everything – as anyone who has just wrapped up a three-hour swiping session on Tinder will attest.
However, they do have a live help service at their homepage to talk you through joining.
Pros: Uses compatibility testing to match you with someone who shares the same worldview as you.
Pros: Free to join and to have limited contact with members.
You can connect with Facebook so getting started is much quicker than with other sites.
A one step Facebook log-in process leads on to a few simple questions (the most obvious – height, kids, whether you drink or smoke), a description and a photo – then you are in. To use the site fully – sending unlimited messages to other members – payment is required.
You can browse a selection of pictures and ages before logging in, anything more specific requires you to become a member. As with many free or low-cost sites, ads can be frequent and feel spammy.
The price and process mean only the dedicated remain – but equally, can lead to people dropping out mid-process.
Controversy swirled in 2010 around its lack of same-sex matching resulting in a site launched later for gay and bisexual daters called Compatible Partners, but e Harmony now offers matching for both mixed and same sex couples from the main homepage.
There’s currently a 7-day free trial to communicate with matches for free until 1 January.
It’s a softly, softly approach – excellent for those new to internet dating or nervous about entering the melee, or using a fast-food dating app like Tinder.
It seems unavoidable that if we have filters and tick-boxes for features and likes or dislikes, we could be cutting off literally thousands of potential suitors because of something we might have thought minor or irrelevant if we met in the flesh.
