PingUp
A location-based social app prototype: send an anonymous ping to someone nearby, and a chat opens only when both of you have pinged each other.
PingUp is a location-based social app prototype. You send an anonymous interest signal, a ping, to someone who is physically nearby right now. If they have pinged you too, it becomes a match, and only then does a chat open.
The structure is simple. A ping does not reveal who sent it, and a match happens only when both people have pinged each other. A one-sided signal never turns into a match, so one-sided approaches do not exist by design. The location constraint narrows the pool further: not a profile somewhere on a server, but a person nearby right now.
It is built with React Native and Supabase, deployed on Railway. Phone number verification is wired in, using Firebase on iOS and Twilio SMS on Android. The full loop from ping to match to chat works. Whether it goes into real operation is undecided.
