Dating App

I registered a dating app called Tinder yesterday with a hope of making friends with foreigners.
My American friend introduced me the app and I tried to use it for the first time.
You can use the app for free at the beginning, but you have to pay in order to use its more functions such as checking pictures unlimited and sending messages.
The price is not that high so I paid the fee and started to use the app to the full extent.
I am not sure if I can make friends with the app but I will continue to use it until I get some friends.
