See your WiFi painted onto a 3D map of your own home. Walk through your rooms with your iPhone. Signl measures the real signal in each one and shows you exactly where it drops, and where to move your router to fix it. WHAT YOU GET - 3D scan: walk through your home and watch the model build itself. LiDAR is used on iPhones that have it. - No LiDAR? Import a floor plan. Drop in a photo or a PDF and Signl reads the rooms. - Coverage map: every room measured and scored, weak spots marked where they actually are. - Live test: real speed and latency, measured from where you stand. Other apps give you a number. Signl gives you a place. Each measurement sits on the room it was taken in, so you know which wall is in the way and where the router belongs.
