Wayfare essentially pairs you with a new friend for a week. You can only have one friend at a time and you can’t pick the gender of your match — to help cut down on those looking to ‘hook up’. It is possible to get a new match: but only if your first pick doesn’t reply within 20 minutes. The app helps get over such issues by pairing more engaged users together to help foster a strong community.
Wayfare Brings Penpalling into the Modern Era – one new friend at a time- for a week – sounds like "musical friends"
