Top 5 WiFi Heat Map Apps Compared
Choosing the right tool depends on your needs—here’s a detailed breakdown:
1. NetSpot (Windows & macOS)
NetSpot excels with its dual survey and discovery modes, supporting both active scans and passive signal mapping. Users can import floor plans, set scale markers, and generate heatmaps for signal strength, noise, and throughput. Its auto-plotting feature saves time, while the pro version adds multi-floor projects and advanced reporting. Ideal for small businesses and tech-savvy homeowners.
2. WiFi Analyzer (Android)
This free app provides real-time signal graphs and channel interference data. Though limited to Android, it’s perfect for quick checks. The heatmap mode requires manual movement to log data points, but its simplicity makes it a favorite for casual users. Notable features include network speed tests and security audits.
3. Ekahau Pro (Windows)
The gold standard for enterprises, Ekahau offers predictive modeling and spectrum analysis. Its AI-driven tools simulate WiFi performance before deployment, saving costly hardware trials. IT teams rely on its 3D heatmaps and detailed reports, though its $4,000+ price tag targets professionals.
4. HeatMapper (Windows)
A free alternative by MetaGeek, HeatMapper uses drag-and-drop floor plans to create basic signal coverage maps. While lacking real-time analysis, it’s user-friendly for home diagnostics. Note: It’s discontinued but still functional on older Windows versions.
5. Acrylic WiFi (Windows)
Acrylic combines heatmapping with deep packet inspection, identifying bandwidth hogs and rogue devices. Its customizable thresholds let users set ideal signal ranges, and exports support PDF/CSV formats. The free version covers basics; paid upgrades unlock historical data.
| App | Platform | Best For | Price |
|---|---|---|---|
| NetSpot | Windows, macOS | Home & SMB | Free/$49-$149 |
| WiFi Analyzer | Android | Quick checks | Free |
| Ekahau Pro | Windows | Enterprises | $4,000+ |
How to Create a WiFi Heat Map
- Upload a floor plan or sketch one in-app (NetSpot/HeatMapper support JPG/PNG).
- Calibrate scale by marking distances (e.g., 10 feet between two points).
- Walk the area while the app collects signal data—more points improve accuracy.
- Analyze results: Red/yellow zones indicate weak signals; blue/green show strong coverage.
