Thread Doctor

Thread Network Diagnostics

Free · In-App Purchases

Your smart home visible: the Thread mesh as a live map — weak links, interference, single points of failure, dying batteries Thread Doctor is an iOS app that maps and diagnoses the Thread mesh behind your Apple Home (Matter) accessories. When smart home devices go unresponsive, respond slowly, or keep dropping off the network, Thread Doctor shows you why — a live graph of your mesh with every router, child device, and Border Router (HomePod, Apple TV), plus signal quality, battery levels, and the weak points likely to cause trouble. The app reads Matter and Thread diagnostic data directly from your paired accessories — no hub, no cloud. Availability of diagnostic values depends on each accessory, firmware version, and platform support. QUESTIONS THREAD DOCTOR HELPS ANSWER • Why do my Matter accessories show "No Response" in Apple Home? • Which device is the weak point in my Thread mesh — and where should I add a router? • Why is my smart home slow or unreliable in one room? • Is Wi-Fi interference affecting my Thread network? • Which battery sensors are about to die? • Which HomePod or Apple TV is my Thread Border Router — and which devices depend on it? FREE FEATURES • Mesh graph View routers, child devices, signal values, link quality, and parent-child relationships reported by your Thread network. • Device details Inspect supported Matter and Thread attributes, including RSSI, LQI, RLOC16, routes, neighbors, Leader Router ID, sleep behavior, battery level, error rate, uptime, and other available diagnostic values. • Possible weak-point detection Thread Doctor highlights routers whose loss may affect connected accessories, based on the topology data available during the scan. • Thread Leader identification See which router is currently coordinating routing decisions in your Thread mesh. • Battery monitoring View battery levels for supported accessories and filter for devices that may need attention. • Every device visible HomeKit-only accessories, Matter-over-Wi-Fi devices, and Thread devices whose firmware hides its diagnostics each get their own list and detail card — nothing silently disappears. PRO FEATURES Thread Doctor Pro adds advanced tools for users who want to track, export, and analyze their mesh over time. • AI Diagnose (bring your own API key) Use your own third-party LLM API key to analyze a structured mesh snapshot. You can preview the outbound payload before sending it, and analysis only starts when you choose to send it. • Scan history Browse past scans, compare snapshots, and review previous network states. • Snapshot export Share the raw mesh as a JSON file — for troubleshooting, social media, own research or 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 App Store’s in-app purchase system. • Your LLM API key is stored only on-device in iOS Keychain. • Matter and Thread diagnostics are read through native APIs • (Optional) AI Diagnose sends data only when you tap Analyze, after you preview the outbound payload REQUIREMENTS • iOS 18 or later • Matter accessories paired into Apple Home • 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.
