There are ways to share your real-time location with people, but doing so typically requires some degree of hassle. People either have to predict how long they want to share their data with someone or manually remember to turn it off later. Google account holders can send a map via Hangouts every couple of minutes and experience some degree of success, but Jink looks like a more elegant solution. The app lets multiple people share their location with a few taps, and the connection will automatically end once everyone meets up.
Sure, this is yet another app that requires your friends to use it in order for it to be worth anything, but sharing the app looks to be as straightforward as we could hope. There is no sign-up required, and users contact each other via their phone numbers. There's also an iOS version, so people don't need a posse of people running Android for things to work out. The app appears to be smart with how it handles sharing, as it will automatically pause Jinks that last longer than two hours and cancel location sharing that exceeds twelve.
The app is still in beta, but it's free to use. Here's a link. Feel free to leave the house, grab some friends, and get back to us with the results.
