more practical than another meter with a big dial. the catch is that walking and scanning your place is a little project, so it makes most sense when your wifi problem is persistent, not just one bad afternoon.

Signl is an iOS app that uses iPhone LiDAR and AR scanning to create a 3D model of your home and measure Wi-Fi signal strength and speed in each room. It visually maps Wi-Fi coverage, scores rooms, identifies dead zones, and suggests optimal router placement. Floor plans can also be imported to generate coverage maps. Scanning and building the model are free; a Pro subscription unlocks full heatmaps, detailed room scores, and shareable reports.
