To chat to with another user you firstly need to be ‘matched’ - this means both users need to swipe right on each other’s profile. Once you’re matched, you can start chatting.
Chatting is completely a FREE feature for everyone.
However, if you wish to skip the matching process, you may send a paid Chattylike to someone to start a conversation. This works like swiping right but with a feature to attach your text message.
To use the Chattylike feature, just tap the smaller like icon on the Swipey screen.
