Robin vs Network Scan

Robin turns your iPhone into a control panel for remote packet capture. It connects over SSH to your own OpenWrt router or Linux host, runs tcpdump remotely, and sends a standard pcap straight back to your iPhone. Robin offers two capture sources: • Air capture — use monitor mode on a compatible Wi-Fi radio to capture 802.11 frames. Robin can scan nearby access points and configure the radio, channel, and width. • Interface capture — capture packets visible to an existing Linux interface such as br-lan or eth0. Monitor-mode support is not required, and Robin does not change the interface state. Robin does not require jailbreaking your iPhone or attaching a USB Wi-Fi adapter to it. The capture runs on the remote host; your iPhone handles connection, detection, configuration, control, and download. Robin is not a generic SSH client. It is a guided workflow built for remote packet capture: • Connect — securely over SSH with password or Ed25519/RSA key authentication. Passphrase-protected private keys are supported, and host keys are pinned on first use. • Detect — check whether air and interface capture are available, including radios, Linux interfaces, required tools, and permissions. • Configure — choose a capture source, channel, or network interface, then add an optional BPF filter, stop timer, and output directory. • Filter — get basic BPF validation as you type, with common examples, a combination builder, and a syntax reference. • Capture — start a detached tcpdump task that keeps running if SSH disconnects. Interface capture excludes the current SSH control connection by default and has a protective file-size limit. • Download — pull the .pcap to your iPhone and open it in Wireshark or your tool of choice. WORKS WITH: • OpenWrt routers, usually with root login • Regular Linux hosts using an existing active network interface • A monitor-mode-compatible Wi-Fi radio for air capture; interface capture does not require one • Root, file capabilities, passwordless sudo, or password-based sudo • Standard Dropbear / OpenSSH targets, with no SFTP required BUILT FOR: Network engineers, Wi-Fi troubleshooters, and security researchers who need a fast, portable way to collect pcaps from infrastructure they own or are authorized to test. GOOD TO KNOW: • Robin requires an SSH-accessible remote device with tcpdump. Only air capture requires Wi-Fi monitor mode. • Captures survive SSH disconnects and can be resumed after reconnecting. • Credentials are stored in the iOS Keychain, never on the remote device. • Air capture on a single-radio router may drop your Wi-Fi control link. Interface capture does not switch the radio mode, and Robin warns you when the air-capture risk applies. Robin is a capture and transfer tool. Use it only on networks you own or have explicit permission to test. Capturing traffic on networks without authorization may be illegal in your jurisdiction.

Who's on my Wi‑Fi? What's that unknown device? Can I reach my server? Network Scan answers all of it. It finds every device on your network, and opens a real SSH terminal to any of them. Discover, diagnose, and connect, all in a clean, native app with nothing to sign up for. SCAN YOUR NETWORK • See every device on your local network with its IP address and open ports. • Group and filter devices (SSH hosts, media and smart‑home gear, newly seen devices) so the list stays readable. • Continuous monitoring keeps watch and shows when devices come online or drop off. • Identifies the maker of many smart-home devices from the built-in IEEE hardware registry — entirely on device. DIAGNOSE AND EXPLORE • Ping and TCP reachability checks, DNS lookups, port scans, and service banners. • A subnet calculator and interface details for quick network math. • Tap any device to see what it likely is, based on its services and open ports. A REAL SSH TERMINAL • Connect to your servers with a full interactive terminal. Run htop, editors, Claude Code, Codex, and other full‑screen programs. • Works with any SSH server: Raspberry Pi, NAS, routers, and home‑lab machines. • Keep multiple live sessions open at once, to the same server or different ones, and switch between them instantly. • Save hosts and store passwords or generated keys securely in the iOS Keychain, unlocked with Face ID or Touch ID. PRIVATE BY DESIGN • No account, no analytics, no ads, no tracking. • Scans, saved connections, and credentials stay on your device. Network Scan is built for home labs, smart homes, and small offices, anywhere you want to understand your network and reach the machines you run. FREE • Network scanning, the grouped device list, ping and TCP reachability, DNS lookups, and recent scan history. PRO (optional) • The SSH terminal with multiple live sessions. • Custom device names, larger port scans, CSV export, and full scan history. • Try Pro free for 7 days with the yearly plan. • Prefer to pay once? Pro Lifetime is a single one‑time purchase. Pro is available as a monthly or yearly auto‑renewing subscription, or as a one‑time lifetime purchase. Payment is charged to your Apple Account.
