ThreadMapper

About

ThreadMapper turns your Thread smart-home network into something you can actually see. Most Thread devices are invisible. They just work — until they don't, and there's no way to tell which one dropped, which room has weak coverage, or whether you need another border router. ThreadMapper answers those questions. WHAT YOU GET • Network health at a glance — an A–F grade with a clear score, plus the specific issues pulling it down • Live mesh map — every device grouped by room, showing how each one reaches your border routers • Room-by-room survey — walk each room and get a coverage grade you can act on • Offline alerts — know the moment a device drops, with a configurable grace period and quiet hours • Device history — 30 days of signal trends, uptime and firmware changes for every accessory • Apple Watch app — your network grade on your wrist, plus a remote for running room surveys hands-free • Home-screen widget and Live Activity for at-a-glance status HONEST ABOUT ITS DATA iOS doesn't expose true radio signal strength for Thread accessories, so ThreadMapper measures response quality instead — and labels it as an estimate everywhere it appears. Mesh links are shown as inferred routing unless you connect an OpenThread Border Router, in which case real routing data is used. No invented numbers. PRIVATE BY DESIGN No account. No analytics. No tracking. Everything stays on your iPhone. The AI features run entirely on device with Apple Intelligence — your network data is never uploaded anywhere. THREADMAPPER PRO — a one-time purchase, not a subscription • AI Insights, Network Assistant and an AI troubleshooter that reads your device's actual history • Resilience Simulator — see exactly which devices would be orphaned if a router failed • 30-day history timeline and topology time-lapse • Diagnostic PDF export for installers or your own records • Weekly reports, health streaks, HomeKit scene triggers and Apple Watch complications REQUIREMENTS ThreadMapper reads your network through HomeKit, so you'll need a home with at least one Thread border router — a HomePod mini, Apple TV 4K or similar. AI features require iOS 26 and an Apple Intelligence-capable device. Want to look around first? Turn on Demo Mode to explore the whole app with a simulated network, no hardware needed.
