App screenshot headed “See your mesh. As a graph.” showing the Thread mesh graph — the Border Router drawn as a half-cyan, half-purple square because it is also the Thread Leader, routers as green circles, end-device accessories as blue dots, and RSSI-coloured links between them. App screenshot headed “Scan your Matter over Thread network.” showing the Topology list — Apple BorderRouter marked as the Thread Leader, Thread devices with router and child role badges, best and worst RSSI values, and battery percentages for end devices like Eve Blinds and the KLIPPBOK water leak sensor. App screenshot headed “Find the routers that orphan your accessories” showing the Re-parent risk screen — routers graded medium and low by how dangerous their loss would be, each listing how many accessories depend on it and how quickly orphans would re-parent. App screenshot headed “AI fixes for your Thread mesh” showing AI Diagnose results — a one-sentence summary and findings that cite exact RSSI values, Thread channels, and accessory names, each with a concrete fix suggestion. App screenshot headed “See all the Thread diagnostic values” showing a device detail screen for the KLIPPBOK water leak sensor — link quality, vendor, product and firmware, plus health values like reboot count, uptime and battery level. App screenshot headed “Use your own AI API keys” showing the AI Diagnose settings — provider and model pickers, a reasoning-effort slider, and a bring-your-own-key field noting the key is stored only in the iOS Keychain on this device.

On-demand mesh graph

The actual Thread mesh, not a guess. RSSI-coloured edges, single points of failure ringed by severity, the Thread Leader marked — even when it's your HomePod.

Re-parent risk detection

Finds routers whose loss would orphan accessories — and grades how dangerous each one really is.

Battery monitoring

Charge levels for every battery accessory in your mesh — Eve, Aqara, Yale, IKEA. Low-battery filter surfaces devices about to drop off.

AI-powered fixes bring your own key

Findings cite real RSSI values, accessory names, and HomeKit rooms — not generic advice. Pay your provider directly.
