Share (but don't overshare) your location
If you think most location-sharing apps are creepy and a little invasive, but still want to share your general location with family and friends, this extension is for you.
Instead of letting the world know precisely where you are at all times, it lets your friend group know what city you're in, and sends you weekly email updates with news about where your friends have moved.
It's easy to lose track of people when you move to different cities. But with this extension, I think you'll find you cross paths with old friends more often than you'd expect.
