You can see who is near to your location, making it easier to meet up.
Behavioral matchmaking engines monitor the behaviour of thousands of users in order to spot common patterns. This knowledge is then used in helping you to find a match, without having to fill in lots of lengthy questionnaires and so on.
By rating the daily matches, you help improve the match-making algorithm of the app. Overtime, the daily matches the app suggests should become better suited for you.
You have to fill out your profile information and answer a general questionnaire (it might be time consuming, but is very useful for finding possible matches).
You can search through singles using filters such as age, education, height or even body type. It is useful if you are looking for something specific.
When you log in with Facebook, it will let you know if you and another user have communal friends. This is useful if you want to find people connected to your circle, or even to avoid meeting people who are connected to you.
This feature is aimed at creating real life meet ups, and fast. You can use it at events such as a concert, or even at a coffee shop to see if there are any singles about.
When you sign in with your Facebook account, it will show you if other app users have liked the same Facebook pages as you.
