On your next pub crawl or night on the town, make following the party easy with Crawlr, an app which allows you to create and find your group, taking the hassle out of event coordination so all you have to worry about is having a great night!
If youre the "group leader", simply create an event with a start/end time and a group name and share it with your friends. Theyll be able to follow you until the specified end time, at which point well automatically stop any location updates.
