Thread Doctor vs ThreadMapper

Thread Doctor maps and helps diagnose the Thread mesh used by your Matter accessories paired in the Home app. When devices go unresponsive, respond slowly, or keep dropping off the network, Thread Doctor helps you see what is happening: routers, end devices, Border Routers, signal quality, battery levels, and possible weak points in your mesh. It reads supported Matter and Thread diagnostic data directly from your paired accessories and lets you change supported Matter device settings. Changes happen only when you explicitly apply them. Available values and settings depend on each accessory, firmware version, and platform support. WHAT IT HELPS ANSWER • Why do my Matter accessories show “No Response”? • Which device may be a weak point in my Thread mesh? • Where should I add another Thread router? • Which battery-powered accessories need attention? • Why did my Matter clock lose the time after a power cut? FREE FEATURES • Mesh graph with routers, child devices, Border Routers, signal values, link quality, and router-child relationships. • Device details for supported Matter and Thread attributes, including RSSI, LQI, RLOC16, routes, neighbors, Leader Router ID, sleep behavior, battery level, error rate, uptime, and more. • Force Sync (time) — set a Matter accessory's clock; shows device time, drift, and time source. • Identify — ask an accessory to blink its light so you can physically find it. • Possible weak-point detection based on topology data available during the scan. • Thread Leader identification. • Battery monitoring and filtering. • Separate lists and detail cards for HomeKit-only accessories, Matter-over-Wi-Fi devices, and Thread devices that hide diagnostics. • Self-reported device faults — radio, network, and hardware faults read from each accessory's Matter General Diagnostics cluster. • Matter device configuration — change supported settings such as power-on behavior, transition times, sensor delays, thermostat controls, and more. PRO FEATURES • AI Diagnose Use your own third-party LLM API key to analyze a structured mesh snapshot. Preview the outbound payload before sending; analysis starts only when you tap Analyze. • Scan history Browse past scans, compare snapshots, and review previous network states. • Snapshot export Share the raw mesh as JSON for troubleshooting, research, social posts, or your own scripts. One-time unlock. No subscription. PRIVACY Thread Doctor is designed to work locally. • No backend, analytics, telemetry, accounts, or third-party SDKs. • Pro unlock is handled through the standard in-app purchase system. • Your LLM API key is stored only on-device in the system Keychain. • Matter diagnostics and configuration changes use native APIs. Settings change only when you explicitly apply them. • Optional AI Diagnose sends data only after you preview the payload and tap Analyze. REQUIREMENTS • iOS 18 or later • Matter accessories paired in the Home app • Wi-Fi connection to the same network as your Border Routers • Optional AI Diagnose requires your own third-party LLM API key NOT A WI-FI NETWORK SCANNER Thread Doctor does not scan Wi-Fi networks. It reads supported Matter and Thread diagnostic information from paired smart home accessories. Thread Doctor is an independent indie project. It is not affiliated with or endorsed by any platform provider, standards organization, or accessory manufacturer.

ThreadMapper shows what your Thread smart home says about itself. Most Thread devices are invisible. They just work, until they don't, and there's no way to tell which one dropped, which border routers you really have, or whether a quiet sensor is asleep or gone. WHAT YOU GET • Network health at a glance: an A–F grade with a clear score, and 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 • Your Thread devices, apart from the rest: the ones that say they are on Thread, and every other accessory labelled for what it is, behind a bridge or not yet known • Mesh map: your Thread devices by room, and the links they report • Offline alerts that respect quiet: a sleepy sensor gets two hours before it is called offline, and devices that go quiet together are one event • Device history: uptime, reboots and firmware changes • Apple Watch app: your grade on your wrist • Home-screen widget and Live Activity for at-a-glance status HONEST ABOUT ITS DATA ThreadMapper shows only what a device or the network states. A device is Thread when it says so. A border router is one the network proves. A line on the map is a link a device reported. iOS doesn't expose radio signal strength for Thread accessories, so there is no signal figure: a device's page shows how quickly it answered, in milliseconds. 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 • 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, place each device where it really is, and see the links your devices report drawn through your real home • 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, 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, such as a HomePod mini or an Apple TV 4K. Border routers are found through Local Network access. AI features need iOS 26 and an Apple Intelligence-capable device. Room scanning needs a Pro-model iPhone with a LiDAR scanner.
