Kestrel Sight
Read full descriptionHide full description
Kestrel Sight brings professional packet capture analysis to iPhone and iPad. Every byte is processed on-device — Kestrel makes no network connections, and collects no analytics. WHAT'S NEW CSV Export — Three profiles: Summary (Excel-ready, 9 columns), Detailed (every protocol layer, ~24 columns), Flow (one row per conversation). Export everything or just bookmarked packets, with bookmark notes preserved as columns. Filenames indicate scope at a glance. Smart Bookmarks — Bookmarking a flow, host, DNS query, or stream now resolves to all related packets in CSV exports. Tap "View" on any bookmark to jump straight to that data with the right filter applied. Expanded Protocol Detection — Added classification for SMB, mDNS, DHCP, NTP, SNMP, SSDP, and QUIC. Dashboard Navigation — Every dashboard widget is now interactive. Tap Total Packets to open Packets, tap a Top Talker to filter Hosts to that IP, tap "TCP" in Protocol Distribution to filter the Packets list, and so on. Subtle chevrons indicate what's tappable. Haptic Feedback — Bike-spoke clicker feedback when scrolling lists. Crisp tap feedback on buttons. Adjustable row density. New filter-bar toggle cycles between Classic, Compact, and Comfortable layouts in the Packets browser. Compact fits ~22 rows per phone screen; Comfortable mirrors iOS Mail's two-line look. On iPad, Classic uses a denser style single-line row. App Switcher privacy. Sight now hides the analysis surface behind the Kestrel logo whenever the app leaves the foreground, so the iOS App Switcher thumbnail and AirPlay mirroring. Faster first-tap haptic response and internal robustness improvements. CORE FEATURES Dashboard — Protocol distribution, encryption stats, top talkers, session summary Packets — Browse and filter with detailed per-layer inspection Raw Data Search — Query any byte sequence in its original form Flows — Bidirectional reconstruction with byte counts, packet counts, timing Hosts — Per-IP profile with traffic stats, port activity, connection mapping DNS — Extract and search all DNS queries and responses Streams — TCP stream reassembly with full-content viewer (auto-runs under 1 GB) Timeline — Visual event timeline with filtering Audit Log — SHA-256 file hashing and session audit log included in PDF exports CAPACITY Up to 1 GB — Full feature set with automatic TCP reassembly Over 1 GB — TCP reassembly disabled; packets, flows, hosts, DNS, and timeline remain fully functional Over 2 GB — Application performance may degrade SUPPORTED FORMATS PCAP, PCAPNG IDEAL FOR SOC analysts reviewing captures away from the workstation Network administrators troubleshooting connectivity Incident responders triaging captures in the field Penetration testers reviewing engagement data Educators and students learning protocol behavior PRIVACY AND SECURITY Zero network access — no outbound connections No analytics, tracking, or advertising Kestrel is designed as an analytical and educational starting point. Always verify findings independently before acting on them. No software can guarantee absolute security; follow your organization's evidence-handling procedures when working with sensitive captures. IMPORTANT NOTES Kestrel analyzes pre-captured PCAP files only — live capture is not permitted within iOS by the platform itself. Screenshots may combine demo and real data. Large captures may extend load times. Devices with 8 GB RAM or more are recommended for multi-gigabyte files. The demo uses fabricated sample packets.

Iron Switch is an encrypted dead man's switch app for protecting crypto recovery phrases, passwords, documents, and final messages—and delivering them to trusted recipients if you stop checking in. Store your most critical information—crypto recovery phrases, passwords, documents, and final instructions—encrypted on your device before it ever leaves your phone. If you're ever unable to check in, Iron Switch securely delivers access to the people you've chosen. Everything is encrypted with AES-256 on your device. Your keys are never sent to our servers in a usable form, so no one at Iron Switch—and no one who breaches our servers—can read your vault. Only you and the recipients you designate can unlock it. HOW IT WORKS • Add your sensitive files, keys, and notes to your encrypted vault. • Choose the recipients who should receive access, plus an optional secondary verifier for added protection. • Set your check-in schedule. As long as you check in, nothing is released. • If you go silent past your window, the switch activates and your designated recipients receive secure access—exactly as you planned. BUILT FOR PEACE OF MIND • Zero-knowledge, client-side AES-256 encryption • Dead man's switch with customizable check-in intervals • Multiple recipients and an optional secondary verifier • Face ID / Touch ID app lock • Two-factor authentication (TOTP) • Offline recovery kit—export a self-contained decryptor so you're never locked out, even if our servers disappear • Delete your account and all data at any time, right from the app IMPORTANT: Iron Switch is NOT a cryptocurrency wallet or exchange. It does not buy, sell, hold, or transact cryptocurrency. It stores your private keys and recovery phrases only as client-side-encrypted text—just like any other note or document in your vault. Iron Switch includes a free plan with real protection: a secure vault, your dead man's switch, and recipient delivery. Secure your digital legacy today—so the right information reaches the right people, exactly when it's needed. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is price: Iron Switch at Free against Kestrel Sight's $1.99. Iron Switch also leads on iOS requirement (15.0 vs 18.6). Kestrel Sight's advantage is in-app purchases (none vs 3). On update cadence, ads and device support there is nothing between them.
