iPhone · Utilities
Scan a room with your iPhone, walk it, and watch the signal paint itself onto the floor you just captured. Then find out exactly where to put the fix.
Weak → strong. The same scale everywhere in the app.
iOS does not let any app read WiFi signal strength. Not a decibel figure, not a bar count. Any app showing you dBm is estimating.
WiFi Heatmap measures what actually decides whether a video call survives: round-trip time to your own router, how much that varies, packet loss, and real throughput — recorded at the spot you were standing.
The LiDAR scanner builds a model of the room as you point at each wall.
Walk around and each square lights up as it is covered, so you know when you are done.
Tell it what you pay for and every room is judged against that, not against the best corner of your own house.
It finds the spot that still has strong signal and reaches the dead zone. Both halves matter.
The 3D model of your home never leaves the device. There is no account, no login, and nothing to delete from a server because nothing was sent to one.
