Radien vs PocketAdmin

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? 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 • 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 and a read of where delay or loss truly begins. Middle-hop noise is never blamed when the destination answers cleanly. • 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. • 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, 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 database is 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: Multi Ping, custom DNS resolvers and extra record types, advanced port presets, full TLS depth, MAC vendor lookup, the app-icon picker, tuning options and sharing. Buy once, keep forever - no subscription. Built by an independent developer. Feedback is welcome and read personally.

PocketAdmin puts a complete network and IT administration toolkit in your pocket. Built for sysadmins, network engineers, and IT support pros, it replaces a bag of single-purpose utilities with one fast, native app, with no clutter and no sign-up to get started. Whether you're chasing a flaky connection, auditing a subnet, SSH-ing into a firewall, or resetting a locked account in the field, PocketAdmin has the tool ready. NETWORK DIAGNOSTICS • Ping: ICMP reachability and latency, with editable packet size, interval, count, and TTL, just like the command line • Traceroute: hop-by-hop path with a visual route map • Test-NetConnection (TNC): combined TCP port and ping check • nslookup: A, AAAA, MX, TXT, NS, CNAME and more • Port Scanner: find open TCP ports fast • Wake-on-LAN: power on a machine by MAC address • HTTP / TLS Checker: status, timing, redirects, and certificate expiry • LAN Scanner: discover every device on your network with IP, hostname, and vendor REMOTE ACCESS • SSH: a real, interactive terminal that runs full-screen apps like vim, top, htop, and tmux. Save hosts and credentials securely in the iOS Keychain, with a special-keys bar for esc, ctrl, tab, arrows, and pipes • Telnet: quick raw TCP sessions WI-FI & CONNECTIVITY • Network Info: connection, IP, DNS, and ISP at a glance • Latency Monitor: live ping graph with jitter • Traffic Monitor: live bandwidth graph • Link Metrics: RSSI, noise, channel, and rates • Wi-Fi Join: apply a network configuration • Bluetooth Scanner: nearby BLE devices and signal strength • Roaming Forensics: build a roam timeline from a log • Coverage Map: walk a room and map Wi-Fi coverage with LiDAR MEASUREMENT • iperf3: full-featured throughput testing with a live graph and complete flag control, including parallel streams, window size, and reverse mode • Internet Speed Test: quick download and upload throughput DIRECTORY • Active Directory: search users, unlock accounts, and reset passwords across multiple directory profiles, protected by Face ID.
