WiFi Heatmap

Why is the Wi-Fi great in the living room but slow in the bedroom? WiFi Heatmap shows you.

Draw a simple plan of your home, place your router, then walk from room to room and tap Test. WiFi Heatmap measures the signal where you stand and paints a coloured heatmap of your home: green where it is strong, red where it is weak.

✏️ DRAW YOUR HOME IN MINUTES
• Rectangles, L-shaped rooms and free shapes, with snapping for straight walls
• Add doors and name your rooms
• Import a floor plan from a photo or PDF and trace over it
• Start from a ready-made template

📶 TEST POINT BY POINT
• Stand anywhere, tap your spot on the map and press Test
• Choose quick or more accurate tests
• Supports homes with more than one router or mesh points
• Signal shown in dBm, percent or simple words

🌈 SEE YOUR COVERAGE
• A clear heatmap over your floor plan
• Weak spots listed room by room
• Simple tips to fix them
• A suggested better position for your router

📊 BEFORE AND AFTER
Moved the router or added a mesh point? Run a new survey and compare it with the old one to see what improved.

📤 SHARE AND KEEP
• Share the heatmap as an image or a PDF report
• Back up your maps to a file and restore them on a new phone

🔒 PRIVATE BY DESIGN
• No account, no sign-in
• Your maps and readings stay on your phone
• Location permission is used only because Android requires it to read the Wi-Fi network name. The app never tracks where you are.

FEATURES
• Works with the Wi-Fi network you are connected to
• Metres or feet
• Light and dark themes
• English, Arabic and Hebrew

Note: WiFi Heatmap measures signal strength, not internet speed. It reads only the network your phone is connected to.

WiFi Heatmap is free and contains ads.

Find the dead spots, fix them, and enjoy full signal in every room.
