WUFI is an app that lets you quickly create any social activity (a WUFI) you have in mind and send a notification to your friends to see who might be interested to join. No need to message this person (SMS? Facebook Messenger? WhatsApp? BBM? iMessage?), call that person, email that other person. No need to bother anyone with a message or call that requires a response. Send a passive notification for your WUFI to all your friends at once, or to friends within a specified range or to certain groups of friends. Those who want to join will be added to your WUFI. Those who don’t, need not reply!
