ProximityPulse: Offline Chat

Messages and photos via Bluetooth — no internet, no servers. Works on airplanes, camping, festivals, emergencies. Messages auto-delete. Total privacy, zero footprint.

Message anyone nearby — no internet, no accounts, no data collection. ProximityPulse uses Bluetooth and Wi-Fi Direct to create instant conversations that never touch a server.

WHY PROXIMITYPULSE? Unlike every other chat app, your messages never leave the space between two phones. No cloud. No sign-up. No trace. Just open the app, pick a name and emoji, and start chatting with people around you.

MESSAGES THAT SELF-DESTRUCT Set a timer from 1 minute to 24 hours, and your messages vanish automatically. Perfect for festivals, classrooms, conferences, or anywhere you want conversations that don't follow you home.

WORKS EVERYWHERE — EVEN OFFLINE No Wi-Fi? No signal? No problem. ProximityPulse works at concerts, on planes, underground, in remote areas — anywhere two phones can be near each other. Zero internet required.

ALWAYS LISTENING IN THE BACKGROUND Advanced Bluetooth Low Energy keeps you reachable even when the app isn't on screen. Get notifications and messages without keeping ProximityPulse open.
