SiteTalkie turns your phone into a mesh-powered messenger that works without internet, cellular, or Wi-Fi. Built for construction sites where signal dies.
Basements. Cores. Rural builds. Deep retrofits. Your phone says "No Service" and suddenly you're walking across the site just to ask one question.
Basements, cores, and sub-structure work are guaranteed dead zones. Your phone is useless.
15 minutes to walk across a site, ask one question, and walk back. Multiply that by every trade, every day.
£50-200 per unit, need charging, get lost or broken. And they can't send a photo of a defect.
Your message hops between nearby phones until it reaches the right person. The more phones on site with SiteTalkie, the stronger the mesh.
No account. No email. No signup. Just pick a display name and you're in.
Tell everyone to download SiteTalkie. The more phones, the better the mesh works.
Your message bounces from phone to phone via Bluetooth until it reaches the recipient. Up to 7 hops.
Public site channel for everyone. Private DMs for one-to-one. All encrypted. All offline.
Send and receive messages with zero internet connection. Works anywhere there are phones nearby.
Free foreverAES-256-GCM encryption on every message. Not even other phones in the mesh can read your DMs.
Free foreverOne public channel everyone nearby can see. Perfect for site-wide announcements and coordination.
Free foreverSend photos of defects, progress, or drawings. Worth a thousand words when you can't walk over.
ProShow your trade or role next to your name. Know who you're talking to at a glance.
ProKeep your messages beyond 24 hours. Never lose track of what was agreed on site.
