WiFi Heatmap: Signal Coverage

See where your Wi-Fi drops, room by room. Walk your home, map each room and find the best spot for your router or extender.

Two bars in the living room, nothing in the bedroom. WiFi Heatmap shows you exactly where your signal dies, and what to do about it.

Walk through your home with your iPhone. The app draws the floor plan as you go, measures the connection in every corner, and paints a colour-coded coverage map: green where it flies, red where it dies.

HOW IT WORKS

1. Mark the corners. Point the crosshair at the base of each corner and tap. You never have to reach them.
2. Walk around. Measurements are taken on their own while you move.
3. Read the map. Your whole home, room by room.

WHAT YOU GET

• A floor plan of your home, drawn by walking
• A coverage map with signal quality in every spot
• A score for every room, worst first
• Where to move the router, before you spend money on hardware
• Saved scans, so you can compare before and after

BUILT FOR EVERY IPHONE No LiDAR. No extra hardware. No floor plan to upload.

YOUR HOME STAYS YOURS Scans never leave your iPhone, and you do not need an account to measure.

ABOUT THE MEASUREMENT iOS does not let apps read the raw signal strength the radio reports. WiFi Heatmap measures what you actually feel instead: how fast and how steadily the connection answers at each point. That is the number that tells you whether a video call will hold.
