WiFi Metric WiFi Metric

Professional WiFi Analyzer to scan nearby networks with Map & List View. Real dBm data, not just signal bars. 專業 WiFi 分析工具,提供 List 清單與 Map 地圖雙檢視,顯示真實 dBm 數值,不只是訊號格數。

Key Features 核心功能

Everything a network engineer or power user needs to diagnose and optimize wireless coverage — in your pocket. 網路工程師與進階使用者所需的一切無線診斷工具,隨身攜帶。

📡

WiFi ScannerWiFi 掃描器

Instantly detect all nearby access points and hidden networks. Updates in real time with every scan. 即時偵測附近所有 AP(包含隱藏網路),每次掃描後立即更新清單。

📶

Signal Strength Meter訊號強度計

Real-time RSSI monitoring in dBm — the true measure of signal power, beyond misleading icon bars. 以 dBm 顯示真實 RSSI,擺脫系統訊號格誤導,掌握實際訊號強度。

🗺️

Map View地圖視圖

Visualize AP distribution spatially within a configurable radius (5 m · 10 m · 30 m · 50 m+). 以圓形或方形地圖呈現 AP 空間分布,半徑可選 5m、10m、30m、50m+。

🏷️

Technical Metadata技術詳細資訊

Tap any network to reveal SSID, BSSID, channel frequency, channel width, encryption type, and estimated distance. 點擊任意網路可查看 SSID、BSSID、頻道、頻寬、加密方式及估算距離。

🔒

Security Info安全性資訊

Quickly identify open vs. protected networks (WPA2/AES, WPA3). Know which networks are safe before connecting. 快速辨別開放與加密網路(WPA2/AES、WPA3),連線前先確認安全性。

📊

List View & Comparison清單視圖與比較

Compare multiple SSIDs side-by-side, sorted by signal strength. Ideal for channel interference analysis. 多 SSID 並排比較,依訊號強度排序,快速識別頻道干擾問題。

Screenshots 畫面截圖

Two views, one powerful tool — List for data density, Map for spatial awareness. 兩種視圖,一個強大工具 — List 清單提供資料密度,Map 地圖呈現空間感知。

List View – network scan

List View — Network Scan清單視圖 — 網路掃描

All nearby APs sorted by signal strength. Color-coded RSSI bars (green / orange) show signal quality at a glance. 依訊號強度排序所有鄰近 AP,RSSI 色條(綠色/橘色)讓訊號品質一目了然。

List View – expanded detail

List View — Expanded Detail清單視圖 — 展開詳細資訊

Tap a network to expand full metadata: BSSID, frequency, channel center, capabilities, Passpoint, and 802.11mc support. 點擊網路展開完整資訊:BSSID、頻率、中心頻道、Capabilities、Passpoint 及 802.11mc 支援。

Map View – radial

Map View — Radial Layout地圖視圖 — 圓形佈局

APs plotted on a circular map centered on your device. Proximity rings reflect estimated distance in meters. 以裝置為中心的圓形地圖,AP 位置依估算距離(公尺)分布於同心圓上。

Map View – rectangular

Map View — Area Layout地圖視圖 — 區域佈局

Rectangular area layout showing the relative positions of all detected APs — useful for floor-plan mapping. 矩形區域佈局,顯示所有偵測 AP 的相對位置,適用於平面圖規劃場景。

Technical Specs技術規格 RAW DATA
