ThreadMapper

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. WHAT YOU GET • Network health at a glance — an A–F grade with a clear score, plus the specific issues pulling it down • Better than yesterday? — a line under the grade saying whether today is up or down on yesterday, and which rule moved it • Every battery in one list — emptiest first, with the room • 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 when a device drops, with a grace period you set (up to 30 minutes) and quiet hours • Device history — 30 days of signal trends, uptime and firmware changes • Apple Watch app — your grade on your wrist, and a remote for running 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 an estimate everywhere it appears. Mesh links are inferred routing unless you connect an OpenThread Border Router. The battery level is what each accessory reports about itself. PRIVATE BY DESIGN No account. No analytics. No tracking. Everything stays on your iPhone, and the AI features run on device — your network data is never uploaded. THREADMAPPER PRO — a one-time purchase, not a subscription • Find that sensor you cannot find — the phone times how fast it answers from where you stand and buzzes faster as you close in, so you can find it without looking at the screen. Works from your wrist too • Where to add a router — ranks the places you actually walked by how much a router put there would lift the weak ones, and says plainly when nowhere would help • AI Insights, Network Assistant and a troubleshooter that reads this device's history, on-device with Apple Intelligence • What the radios say — why a device rebooted, how often it changed parent router, how often a battery device wakes, and how many apps and households can still control it • AR room mapping and X-Ray — scan rooms into a floor plan, walk the signal onto it, then see the mesh through your real home, with your survey walk drawn on the floor as a coloured ribbon • Your year on one card, your mesh as a twenty-second film, and as an A2 poster a print shop will take • A year of daily grades on one calendar — no Apple Intelligence needed — a month of history, weekly reports, and when your home is at its worst • Export every health sample, daily grade and battery reading as CSV or JSON — the rows themselves, not a report about them — and import them on a new iPhone • Jobs and evidence sheets — a page for a client showing what a visit changed, and a page per device for a warranty claim • Device groups, multiple homes, scheduled reports and a pinned-devices widget 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 need 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.
