🔍 WiFi Signal Overview
View all nearby WiFi networks on an interactive real-time signal graph. See signal strength, channel overlap, and interference at a glance. Switch between 2.4 GHz, 5 GHz, and 6 GHz views. Tap any network for full details including encryption, channel width, WiFi standard, and router manufacturer.
📊 Channel Recommendation
Not sure which channel to use? The wifi analyzer recommends the optimal channel by scanning all detected networks, calculating interference scores, and showing you exactly which channel will give optimal performance — for both new and existing access points.
⚡ Speed Testing
Internet Speed Test — measure your ping, download speed, and upload speed against worldwide servers. Results appear in real time with a clean 3-column display.
WiFi Speed Test — measure the actual throughput between your phone and your router over your local network. Great for checking if your WiFi link is the bottleneck.
🗺️ WiFi Heat Map
Upload your floor plan, walk around, and tap to measure. The app builds a color-coded signal map showing exactly where your coverage is strong, weak, or dead. Essential for placing routers, extenders, or access points.
