SiteTalkie

Message your whole construction site without signal. SiteTalkie uses Bluetooth mesh to send texts, photos, voice notes and emergency alerts — no internet needed.

SiteTalkie turns every phone on your construction site into a walkie-talkie. No signal? No WiFi? No problem.

Your messages hop phone-to-phone using Bluetooth mesh — reaching across floors, through basements, and into dead zones where nothing else works.

WHAT IT DOES

• Instant site-wide messaging — everyone on the mesh
• Direct messages — private conversations with individuals
• Emergency alerts — full-screen fire, medical, and safety broadcasts to every phone on site
• Photos and voice notes — share what you see, hands-free updates
• Real-time radar — see who's nearby, what floor they're on, and how far away they are

BUILT FOR CONSTRUCTION

• Works offline — no internet, no mobile signal, no WiFi required
• AES-256 encryption — every message is encrypted end-to-end
• Glove-friendly — large touch targets, high contrast, dark theme
• GPS radar with compass and floor detection
• Ghost mode — hide your location when you want privacy
• Trade badges — show your role on site

HOW IT WORKS Open the app. That's it. SiteTalkie automatically finds other phones running the app nearby and creates a mesh network. Messages hop from phone to phone — up to 7 hops — covering your entire site.

More phones = stronger mesh. Share with your site team.

SAFETY FIRST Emergency alerts override everything. One tap sends a full-screen alert to every phone on the mesh — fire evacuation, medical emergency, crane operations, or general warnings. Safety alerts will always be free.

Built in the UK for UK construction sites.
