WiFi Heatmap

WiFi Heatmap is a smart WiFi analyzer that transforms how you understand and optimize your wireless network coverage. Whether you're troubleshooting weak signals at home, planning office network expansion, or concerned about electromagnetic exposure, this app delivers instant visual insight into your WiFi environment.

Visualize signal strength instantly with automatic heat map generation. Simply walk around your space while the app's built-in movement detector takes continuous measurements—no manual data entry required. You'll immediately see exactly where coverage is strong and where dead zones exist, making it easy to identify the best locations for access points or determine if additional repeaters are needed.

Get comprehensive WiFi analysis through multiple powerful tools. Monitor channel usage to identify interference from neighboring networks, track signal strength history over time, and detect beacon frames from nearby access points. The app supports both 2.4GHz and 5GHz bands with HT/VHT channel width detection up to 160MHz, ensuring you can optimize modern routers effectively. Choose from multiple color scales to visualize data the way that makes most sense to you, with full pan and zoom controls for detailed inspection.

Optimize your network performance by identifying the best WiFi channels for your router. Interference from overlapping networks degrades speed and stability—WiFi Heatmap shows you exactly which channels are congested and which offer the clearest transmission. This insight is invaluable for anyone managing wireless networks across multiple rooms or floors.

For users concerned about electromagnetic pollution, the heatmap reveals precisely where WiFi radiation exposure is highest, helping you designate safer rest areas in your home. This makes the app equally useful for health-conscious households and professionals managing workplace wellness.

Advanced users can pair the app with an external SS11 sensor for dramatically faster scanning, probe request detection, and elimination of scan throttling limitations—enabling professional-grade analysis. Save your projects to internal or external storage for future reference, or share results with colleagues and contractors.

The app includes a comprehensive user guide with Google Translate support and works in multiple languages. WiFi Heatmap works on any Android device with an accelerometer; automatic movement detection requires magnetic sensor support, with manual scan mode available as a fallback.

Take control of your wireless network today. WiFi Heatmap gives you the visibility to make smart decisions about coverage, performance, and safety.
