Are you really safe on Public Wi-Fi?
Hackers and snoops could be lurking on the same hotel, cafe, or airport network. Wi-Fi Analyzer & Device Scan (powered by Public Wi-Fi Defender) is your ultimate network security tool to instantly check if your connection is safe, detect who is on your Wi-Fi, and measure your internet speed—all in one tap!
🌟 CORE FEATURES (5-in-1 Network Toolkit)
🛡️ 1. One-Tap Security Diagnosis
Instantly detect dangerous networks. We check for Captive Portals and potential Man-in-the-Middle (MITM) attacks. Know immediately if your connection is "Safe" or "Danger" before your personal data gets compromised.
🔒 2. Wi-Fi Encryption Checker
Are you on a secure WPA2/WPA3 network or an exposed "Open" Wi-Fi? We analyze the encryption level of your current connection and warn you about vulnerable networks.
📱 3. Who is on my Wi-Fi? (Device Scanner)
Curious about who is sharing your network? Run a fast Ping scan to list all connected devices and their IP addresses. Want to know if it's a phone, laptop, or camera? Unlock our smart "Device Type Identifier" to see exactly what hardware is lurking on your network!
🌍 4. Public IP & Location Map
Discover how the internet sees you. We display your external Public IP address and show your approximate geographical location directly on an interactive map.
🚀 5. Internet Speed Test
Is the free Wi-Fi actually fast enough? Run a quick and accurate download speed test (Mbps) to see if you can stream videos, play games, or work smoothly.
✨ PREMIUM PRIVACY & EXTRAS
100% On-Device Analysis: Your privacy is our absolute priority. All network scanning and parsing happen locally on your phone. We NEVER send your location, IP, or network data to external servers.
