Echo Chat

About this app

Echo is a proximity-based social app that helps you connect with people who are physically nearby — in the same room, event, or space.

There’s no global feed, no algorithms, and no endless scrolling. Echo works only in the here and now.

How it works

When you’re in a shared location (like a concert, campus, café, or conference), Echo creates a temporary digital bubble using nearby device discovery. Inside that bubble, you can see and chat with people around you — instantly.

When you leave, the bubble fades. Connections are temporary unless both people choose to keep them.

Why Echo is different

No algorithms – nothing is ranked, boosted, or hidden

No public feed – only people who are actually nearby

Real presence first – online interaction starts offline

Ephemeral by design – moments don’t live forever unless you want them to

Perfect for

Events, conferences, and meetups

Campuses and study spaces

Concerts and festivals

Casual social discovery in real life

Privacy-first

Echo is built with privacy in mind. Location and proximity data are used only to enable nearby discovery and are processed in real time. There are no ads and no selling of personal data.

Echo brings social networking back to real life.
No feeds. No noise. Just people — here and now
