## What is NetGraph?

NetGraph is a professional Wi-Fi site survey and heatmap app for network engineers, IT teams, installers, and low-voltage integrators.

From floor plans and field measurements to visual analysis and client-ready reports, NetGraph helps you find weak coverage, channel interference, roaming issues, latency, packet loss, and other network problems in one organized workflow.

PROJECTS & FLOOR PLANS

• Organize survey data by customer, project, and floor
• Import floor plans from Photos or Files
• Calibrate plan scale and choose the site type and survey precision
• Define target Wi-Fi networks and manage sample points and measurements
• Place routers, access points, and wireless controllers directly on the plan
• Import, export, and archive project packages
• Open project files created with earlier versions of NetGraph

ON-SITE SURVEYS

• Capture measurements immediately or plan sample points in advance
• Create, move, and manage sample points on the floor plan
• Add photos and notes, and flag locations that need to be surveyed again
• Show each point's name or its current metric value
• Keep every measurement tied to its real location for easier review and comparison

WI-FI DIAGNOSTICS

On Mac, NetGraph provides deeper Wi-Fi scanning and RF analysis, including:

• Signal strength, signal-to-noise ratio, and noise
• Channel, band, BSSID, and link rate
• Wi-Fi standard, security, and IP details
• Nearby access points, channel utilization, and interference conditions

On iPhone and iPad, an optional Shortcut can collect enhanced Wi-Fi details during mobile surveys.

NETWORK PERFORMANCE TESTING

Measure real-world network performance in addition to wireless signal quality:

• Internet and local network latency
• Packet loss
• Download throughput
• Upload throughput

Configure separate Internet or LAN test targets to help determine whether an issue comes from Wi-Fi coverage, the local network, or the upstream connection.

WI-FI ROAMING TESTS

• Observe transitions between access points
• Track AP changes, latency, packet loss, and connection events
• Save and review previous roaming sessions
• Export roaming results as PDF

Ideal for multi-AP environments such as offices, hotels, schools, retail spaces, and warehouses.

MULTI-METRIC HEATMAPS

Turn floor plans and survey measurements into heatmaps for signal strength, SNR, noise, link rate, download and upload throughput, latency, packet loss, and more.

• Compare multiple metrics side by side
• View plain-language explanations for each metric
• Customize heatmap color palettes
• Label points with their names
• Label points with the metric shown on the current heatmap
• Hide points completely for a clean heatmap view

PNG & PDF EXPORT

• Export heatmaps as PNG images
• Create multi-page PDFs covering multiple floors and metrics
• Generate a separate image or PDF page for each floor and metric combination
• Choose the floors, metrics, and filename order
• Show or hide sample points, network devices, and metric explanations
• Display point names or the metric value for the current export page

BUILT FOR MAC, IPHONE & IPAD

The complete project, survey, performance testing, roaming, heatmap, and export workflow is available across Mac, iPhone, and iPad, with controls tailored to each device.

Mac adds more comprehensive Wi-Fi scanning, channel utilization, and nearby interference analysis. iPhone and iPad make it easy to walk the site, collect measurements, verify fixes, and present results in the field.

NetGraph supports English and Simplified Chinese, as well as Dark Mode, bringing Wi-Fi surveying, troubleshooting, and reporting together in one clear workflow.

### 5/5 — 测试无线很好用

*2026-07-27*

简单好用的无线网热力图APP，用来做项目验收很方便。

### 5/5 — 很好用

*2026-07-20*

解决了苹果手机Wi-Fi里看不见连接速率和信号强度的问题

### 5/5 — 入户前测网络质量非常好

*2026-07-02*

最近帮客户装修搞网络，现场没通网，中兴app上热力图也用不了，ios上找了好几个软件想测网络并且带热力图的，都找不到，没想到在小红书找到这个软件，用下来发现功能全面和专业，而且在小红书留言开发者，开发者会认真倾听并且积极改进，更新速度非常快，越来越好用了，推荐！

### 5/5 — Nützliche App

*2026-06-20*

Die App gibt nützliche Informationen zum Wifi Netz. Nun auch auf Englisch.

**Developer response:** On iOS: Go to “设置” in the bottom right corner, then select “English” under “语言”.  
On Mac: From the top menu bar under App name, choose “设置” or use the shortcut “Command+,”, then find “语言” under the first tab “外观” and select “English”.  

In version 1.0.2, the language logic has been optimized so that English is set as the default in non–Simplified Chinese environments.

### 1/5 — Leider nur Chinesisch

*2026-06-15*

Die App sollte Englisch sein, ist aber nur Chinesisch in allen Menüs. Der Support hat eine ungültige Adresse.  Ich kann leider kein Chinesisch.
