2 of 5 — What it does

• Group chat

  One shared conversation for everyone running Buzzbelt nearby, and a direct message to any one person in range. Nobody in reach when you send? It's marked undelivered, not lost — send it again once somebody is.

  "Nobody is in reach. Not delivered — try again once somebody is."

• Buzz

  Rings every phone in reach at full volume and takes over the screen, even locked in a pocket. It is how you get thirty heads to look up at once. Rate-limited on purpose, so it keeps meaning something.

  "12 phones will ring at full volume, right now."

• Who's reachable now

  A headcount of the phones yours can actually hear, updating on its own. When it cannot tell — because you stopped looking, or the radio is off — it shows a dash. Never a confident zero.

  "— of 30 reachable · not looking"

• Reaches your pocket, not just your screen

  A buzz rings and vibrates even with the phone locked away, and a new message names who it's from the moment it lands. Tap it and you're straight in that conversation.

  Nobody has to be staring at the app for it to reach them.

• Nothing to sign up for

  Open the app, type the name you want the group to see, and that's the whole join. No account, no phone number, no data sent anywhere — there's no server for it to go to.

  Nothing about you is collected, tracked, or sent anywhere.
