**Net Analyze Defender** is a network diagnostics and toolkit app for everyday and power users. It helps you check connection status, latency, and connectivity on iPhone and iPad. **Core Features** • **Home Network Status** Live connection type (WiFi / Cellular), latency (from real ICMP ping), signal strength, and local / external IP. A health score combines latency, DNS, and signal for a quick overview. • **Quick Tests** - **Full Assessment**: Multi-round tests for connectivity, latency (ICMP ping), DNS resolution, download speed, and stability (packet loss), with an overall score and report. - **Ping Test**: Custom target and count; real ICMP ping (SimplePing) with latency and packet loss stats. - **Download Speed**: Measure current download bandwidth. • **Pro Tools (Toolbox)** - **Ping**: ICMP ping to any host or domain with RTT and statistics. - **Web Test / Web Analysis**: Page load time or request and resource analysis. - **Download / Upload**: HTTP bandwidth tests. - **Traceroute**: See each hop to the target. - **LAN Scan**: Discover devices, open ports, and response times on your network. - **DNS**: Resolve domain names to IPs and more. - **Whois**: Domain registration lookup. - **Port Scan**: Check open ports on a host. - **WiFi Info**: Current WiFi details. - **SSL Certificate**: View site SSL certificate info. - **HTTP Analysis**: Request/response headers and more. - **Bonjour**: Discover Bonjour services on the LAN. - **IPv6**: IPv6 connectivity check. - **Proxy**: System proxy detection. - **DoH (DNS over HTTPS)**: Encrypted DNS resolution test. - **Congestion**: Compare idle vs loaded latency to gauge congestion. **More** • **Simplified Chinese / English** in-app language switch. • Free tier has limited daily uses per tool; subscribe to Pro for unlimited access and ad-free experience. • Latency and stability use real ICMP ping when possible; if ICMP is blocked, HTTP fallback is used so the home screen and full assessment still show meaningful latency. Ideal for network admins, developers, and anyone who wants to understand or troubleshoot their network. 【Terms of Use (EULA)】 https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
