6. happn
This app ranks 6th in our list of best free dating apps for Android phones. It is all about coincidences and random encounters. It was created in France, but quickly spread to the UK and the United States. The start is almost the same; you link the app with your Facebook account and then you set the preferred age and radius. Then the app uses your GPS to track your movements and matches you with a user with whom you crossed paths. You can send a “charm” to the user you like and then wait. If you get a “crush”, congratulation, you can communicate. If not, you’ll have to find someone else.
