You can use the location of the device and store the lat and long of the device in the backend(probably AWS if you are using it!).<\/p>\n

Every device registers to your app will be sending its realtime lat and long to your backend. <\/p>\n

You can have some sort of computation or graph-based analysis in the backend and check if two devices have a really small difference in their location parameters. If so, then you can use SNS(Available in AWS) and Firebase, to send a push notification, to notify the user.<\/p>\n<\/p><\/div>\n
