Radien: Network Toolbox

Ping, DNS, TLS & port scanner

Free · In‑App Purchases · Designed for iPad

Runs entirely on your device. No ads, no trackers, no analytics. Ping, traceroute, DNS, port and TLS checks, plus subnet, IP and MAC tools. Honest and private. Radien is a native network-diagnostics toolbox for iPhone and iPad — and it's honest about what it can and can't see. Every tool runs directly on your device. 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. • Multi Ping — compare up to four hosts side by side, at once. • Traceroute — every hop between you and a destination, with reverse-DNS names and an honest read on where delay or loss 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. • Port Scanner — see which TCP ports are open, closed or filtered, over an honest model — never a fake vulnerability claim. • TLS Inspector — read a site's real certificate chain, protocol versions and cipher support, straight from your device. No third-party grading service. • Subnet Calculator — IPv4 and IPv6 math: CIDR, network, broadcast, host ranges and equal splits, with a live bit view. • IP Converter — turn any IP notation into every other form, and see how an IPv4 address rides inside IPv6. • MAC Converter — every MAC notation, EUI-64, link-local, and a fully offline vendor lookup. Randomized phone MACs are flagged honestly, never given a fake vendor. PRIVATE BY DESIGN Radien uses Apple frameworks only — no third-party SDKs, no analytics, no data collection. 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.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

Radien now correctly lists all nine of its languages on the App Store: English, Chinese (Simplified), Japanese, Spanish, German, French, Portuguese, Korean and Italian. You could always switch between them inside the app; now the store page says so too. The app itself is unchanged.
