Radien vs SimpleNet Tools

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 or server on your network, 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.

SimpleNet Tools is a focused network toolkit for IT folks who need basic checks from a phone — without ads getting in the way. Run common diagnostics on the go: ping a host, look up DNS records, check a TCP port, follow a traceroute, probe TLS and certificates, look up whois/RDAP registration, and estimate IP city/ISP/ASN. Native ICMP and TCP run on iOS production builds so results reflect real network behavior from your device. TOOLS • Ping — ICMP echo with latency, loss, and jitter • DNS — A, AAAA, CNAME, MX, TXT, and NS via the resolver you choose (device DNS where available, or Cloudflare) • Port — TCP connect check: open, closed, or filtered • Trace — ICMP traceroute with hop-by-hop TTL probes • TLS — HTTPS reachability, security headers, and certificate transparency lookup • Location — IP city, ISP, and ASN (including this device’s public IP) • Whois — RDAP registration for a domain or IP: owner, registrar, dates, nameservers EXTRA • Saved addresses — keep frequent hosts on-device for quick re-use • About — version, release notes, Terms, and Privacy No account. No ads. No in-app purchases. You choose the host or address to test; checks run from your device. Made by anollopa for people who just need simple network commands on mobile.
