SignalMap is an on-device Wi-Fi fixing assistant for your home. Choose the workflow that fits your iPhone: HOME MAP On a LiDAR-equipped iPhone, scan one room at a time while SignalMap collects clean, stationary checks against your router. Name each room, merge the floor plan, see measured weak areas, and get one practical router, mesh-node, or access-point test. QUICK ROOM CHECK On any iPhone, check the main router and the rooms that matter most. SignalMap compares those spots and tells you whether to keep the current placement, fix the source connection first, or test added coverage toward a weak room. VERIFY THE CHANGE After moving a router or testing a node, repeat the same route. SignalMap compares the new average and weakest-area result against the saved baseline so you can keep only changes that actually help. HONEST BY DESIGN - Measured dots come from real local-router response checks. - Estimated map areas are clearly separated from measured evidence. - Failed router probes are shown as unavailable, never as fake dead spots. - Precise placement percentages appear only when the scan supports a strong calibrated model. - SignalMap does not claim access to raw Wi-Fi radio strength, channel congestion, or nearby network scans that iOS does not provide to ordinary App Store apps. PRIVATE BY DEFAULT No account, ads, analytics, or cloud upload. Scans and measurements stay on your iPhone unless you choose to share a scan file. Home Map requires a LiDAR-equipped iPhone and maps one floor at a time. Quick Room Check works without LiDAR or camera access.
