Radien vs Network Hamster

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 • Radien Checkup: one run checks your Wi-Fi, router, internet, DNS and websites, and tells you what is wrong. • 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: Radien Checkup, Multi Ping, custom DNS resolvers and extra record types, advanced port presets, full TLS depth, MAC vendor lookup, alternate app icons, tuning options and sharing. Buy once, keep forever. No subscription. Built by an independent developer. Feedback is welcome and read personally.

Your internet is acting up. Is it your Wi-Fi? Your router? Your ISP? Network Hamster tells you — in plain English. A helmeted hamster pedals a bicycle in real time, matched to your actual latency. Fast connection, fast pedaling. Congested network, and he grinds to a crawl. It's the most honest status indicator you'll ever install. Behind the mascot is a genuinely serious diagnostic toolkit. ONE-TAP DIAGNOSIS Tap Diagnose and get eight checks in under a minute: interface, captive portal, your router versus the internet, NAT topology, DNS, web response time, and latency under load. Then a verdict in words you can act on — "Local network is healthy, high latency is upstream. Your router is not the problem." BUFFERBLOAT GRADING The reason your video calls stutter when someone downloads something. Network Hamster measures how much your latency balloons under load and grades it A+ through F, then tells you exactly how to fix it. FIND OUT WHERE YOU STAND • Live ping, jitter, packet loss, and p95 latency across six rotating servers • Speed test with download, upload, and bufferbloat, plus saved history • Router vs. internet isolation — know instantly whose fault it is • CGNAT, double NAT, and symmetric NAT detection • DNS benchmarking against Cloudflare, Google, and Quad9 ADVANCED TOOLS • Monitor Mode — ping every second for hours, graph the whole session, get alerted the moment your connection drops, and export CSV • MTR traceroute with per-hop whois, reverse DNS, and a map of where your packets actually travel • Ping Lab — test with different packet sizes to expose MTU and queueing problems • Buffer Probe — detects undersized modem buffers that quietly cost you the bandwidth you pay for • Wireless Health — tells you whether jitter is born on your Wi-Fi or upstream • Wi-Fi Guard — catches repeated forced disconnects • Inbound Watch — spots unusual traffic arriving at your device • Cellular coverage mapping and DNS record lookup PROVE IT TO YOUR ISP Every diagnosis exports as a shareable report: latency per server, packet loss, traceroute, bufferbloat grade, and a timestamped event log. Stop arguing from memory. Paste the evidence. BUILT HONESTLY Some things iOS simply does not allow — Wi-Fi signal strength, raw packet capture, cell tower identity. Network Hamster never fakes them. Where a limit exists, the app says so and does the most useful thing that is actually possible. No account. No tracking. No data collection. Just a hamster who is very concerned about your ping.
