Live mesh graph
Pulls neighbour tables from every Matter accessory and renders the real Thread mesh — not a guess. RSSI colour-coded, articulation points ringed in red.
Single points of failure
Tarjan's articulation-point algorithm identifies routers whose loss would orphan accessories. You see exactly which devices are at risk.
AI-powered fixes
Bring your own Anthropic or OpenAI key. Get specific, actionable findings citing real RSSI values and accessory names — not generic advice.
Border Router discovery
mDNS browsing identifies your HomePod / Apple TV / standalone OTBR by name. No more cryptic BR R34 labels in the topology.
Scan history
Last 20 scans persist on device. Browse past snapshots to see how the mesh evolves and catch regressions.
100% private
No backend, no analytics, no proxy. The developer never sees your data. Your LLM API key lives in your iOS Keychain, this device only.
