See your WiFi in 3D. Walk through your home, watch the signal paint itself onto your rooms, and find the exact spot where it dies. 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. YOUR SCANS STAY ON YOUR IPHONE The 3D model of your home never leaves your device. Nothing is stored on our servers. Floor plan photos are analyzed, then discarded. FREE AND PRO Scanning your home and building the 3D model are free. Signl Pro unlocks the full coverage heatmap, scores for every room, router placement recommendations and shareable reports.

Now you can scan your home without a single interruption. Signl explains what it needs, and why, before asking for it. Readings of speed and latency are sharper. Your coverage map appears faster once you stop walking. Walk your home. Watch the signal paint itself onto your rooms. Find the exact spot where it dies.
