iOS: Meeting up with people is often difficult because it's hard to tell exactly where they are or how long it will take them to arrive. Routeshare takes out the guessing and sends real-time updates of your location to a person of your choosing, then stops broadcasting when you arrive.
Routeshare is incredibly simple to use. Just launch the app, then select a recipient to send your location to. The app will send them a link that leads to a map with your location and estimated arrival time. They don't need to have Routeshare installed to view the map, and the second you arrive at your destination, you get your privacy back. It's a handy way to share your location occasionally without leaving it out in the open all the time.
