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?

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.
