Wi-Fi 3D

See how your current Wi-Fi connection behaves around a room. Open the camera, explore the space and leave colored AR markers where your iPhone takes a measurement. Start a survey, hold still for about two seconds, then move at least 40 cm for the next point. Green, yellow and red show estimated connection quality. Grey means there is not enough information to rate it. Wi-Fi 3D measures response time and unanswered requests to your local router. On iOS 26, it also uses the system's connection-quality estimate when available. It does not measure radio signal strength or internet download speed. Routers that block requests can limit results. Pause or clear the survey at any time. Points stay only in the current session and are cleared when the network changes or the app process ends. Camera processing and measurements stay on your iPhone. No account, ads or in-app purchases. Camera and local-network access are required. Location permission is optional and only used to show the Wi-Fi name. Requires an ARKit-compatible iPhone with iOS 17 or later.
