Why is finding friends at a concert almost impossible?
Quick answer
When you lose friends in a concert crowd, Parages alerts you the moment one you added returns to within a few hundred metres, without anyone sharing live location.
One trip to the bar and the crowd swallows your friends whole. Phone signal crawls, the support act is too loud to call, and "I'm near the sound desk" means nothing in a sea of ten thousand people. Parages cuts through it. The app notices when a friend you added moves back into range and pings you. You stay connected without broadcasting where you are to anyone.
In one sentence
Parages pings you when you pass near a friend. It tracks nobody.
