Radien vs Network Radar Ultra

Is it my Wi-Fi, or is the site down? Where does the connection break? Why does Safari distrust this certificate? Is my public IP really mine, or am I behind my carrier's NAT? Did my computer really wake up? Radien answers these questions on your iPhone or iPad, directly on the device, and honest about what it can and can't see. No ads, no trackers, no analytics, no accounts. Nothing you type is sent to a server we operate. WHAT'S INSIDE • Radien Checkup: one run checks your Wi-Fi, router, internet, DNS and websites, and tells you what is wrong. • Wake on LAN: wake a computer, NAS, server or gaming PC on your network, or away from home through your own VPN, then watch it wake. Radien sends the Magic Packet, watches for an answer, and says whether it woke and what to check if it did not. Siri, Shortcuts and widgets can wake it too. • Ping: latency, jitter and packet loss to any host, with a live chart and a plain-language verdict. Your router is one tap away. • Multi Ping: compare up to four hosts side by side, at once. Saved groups load a whole comparison in one tap. • Traceroute: every hop between you and a destination, with reverse-DNS names, the network that holds each address, and a read of where delay or loss truly begins. • DNS Lookup & Reverse DNS: query A, AAAA, MX, TXT, NS and more against the system resolver or Google, Cloudflare and Quad9. Enter an IP for a reverse PTR lookup and the network that holds it. • Port Scanner: which TCP ports are open, closed or filtered (usually a firewall), never a fake vulnerability claim. • TLS Inspector: read a site's TLS/SSL certificate chain, protocol versions and cipher support, straight from your device. No third-party grading service, no invented grades. • Subnet Calculator: IPv4 and IPv6 math: CIDR, network, broadcast, host ranges and equal splits, with a live bit view and RFC-correct /31 and /32. • IP Converter: turn any IP notation into every other form, and see how an IPv4 address rides inside IPv6. • MAC Converter: every MAC address notation, EUI-64, link-local, and a fully offline vendor lookup. Randomized phone MACs are flagged as randomized, never given a fake vendor. • Network Details: your Wi-Fi name and access point vendor, local and public IP address with its network owner, router address, DNS servers, your real cellular radio (5G, or 5G riding a 4G core) and NAT64 detection, one tap from the always-on status header. ACCESSIBILITY Every screen is tested by hand with VoiceOver. Result rows read as one sentence, every long-press action is also a rotor action, and the ping chart supports Apple's Audio Graphs, so you can hear your connection as rising and falling tones. Larger Text, Reduce Motion and Voice Control are supported. One honest limit: I have no Braille display, so Braille output is untested. PRIVATE BY DESIGN Radien uses Apple frameworks only: no third-party SDKs, no analytics, no data collection. The MAC vendor and network owner tables are bundled on the device, and certificates are read locally, never sent to a checking service. Your network is your business. RADIEN PRO Radien is free to use, with a one-time Radien Pro unlock for the power features: Radien Checkup, Multi Ping, more Wake on LAN devices with groups, widgets and the Control Center control, custom DNS resolvers and extra record types, advanced port presets, full TLS depth, MAC vendor lookup, network names, alternate app icons, tuning options and sharing. Buy once, keep forever. No subscription. Built by an independent developer. Feedback is welcome and read personally.

Network Radar Ultra finds devices on your local network and clearly shows what is actually reachable: IP addresses, device types, open ports, web interfaces, and local services. Start a scan on the connected WiFi network and identify routers, repeaters, cameras, printers, NAS, Sonos, Apple TV, smart home devices, KNX/IP, Home Assistant, and unknown devices. Bonjour/mDNS, UPnP/SSDP, ONVIF, HTTP hints, and TCP port checks are combined so names, models, and device types appear as cleanly as possible. The analysis gives you a clear network summary: • found devices and device types • open ports and web interfaces • Bonjour and UPnP/SSDP services • ONVIF/RTSP hints for cameras • notable or unknown devices • scan history with comparison The tools section includes practical network diagnostics: • reachability check • port check and port range check • DNS records and reverse DNS • HTTP check and HTTP headers • SSL/TLS certificate check • subnet calculator • IP info • Wake-on-LAN Scans and saved results stay local on your device. Public IP and IP info lookups use HTTPS requests to external services only when you start them. Network Radar Ultra is made for people who want to understand their WiFi without a command line, expert knowledge, or complicated network tools.
