The site looks into making perfect matches by analyzing the personality, values, ideals, lifestyle, and preferences of the users.
As the name suggest the site is for those who want long-term relationships and avoids those who are interested in just casual dating.
But the app has fallen in popularity compared to Tinder, and the fact that you can receive messages from anyone - without matching first - means that your inbox can quickly become clogged with sleaze. It matches you with people based on your location and a shared interest in music.
It can import your favourite tunes from your smartphone or and does the hard work for you by collating matches.
Before you join, the app has to approve you as a member (a slightly daunting process) or you have to be invited.
If you want to unlock certain features you either have to pay or invite other to join.
e Harmony was developed by Neil Clark, a psychologist and the author of relationship advice books. It is the questionnaire in the profile that decides whether you are eligible for the matching process.
