How do you know when a friend is in town?
Quick answer
Parages pings you when a friend you added comes into town near you, so a passing visit becomes a meetup instead of a missed one, without any live location sharing.
A friend passes through your city, assumes you are busy, and never says a word. You find out afterward and both of you feel a little robbed. Parages closes that gap. Add the people you want to see, and when one of them comes within range of you, your phone tells you they are around. A quick "You're here? Let's meet" replaces the regret of a visit you never knew about.
In one sentence
Parages pings you when you pass near a friend. It tracks nobody.
