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.
Every tool is fully usable with VoiceOver, and the ping latency chart adopts Apple's Audio Graphs, so you can hear your connection as rising and falling tones instead of reading it.
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.
ACCESSIBILITY
Every screen was tested by hand with VoiceOver. Result rows read as a single sentence, every long-press action is also a rotor action, and runs announce when they start and finish. Larger Text, Reduce Motion and Voice Control are all 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. Your network is your business.
