Diagnostics that are easier to review and share • Export structured PDF reports with measurements, observations, test context and the limits of available results. • Organize site work with site dossiers and comparable measurements. • Pair devices with a guided flow and clearer connection details, including manually entered sensors. • Compare measurements between compatible devices and review available endpoint resource data. Missing data stays explicitly marked rather than being replaced with assumed results. • Improved layouts on iPhone Duo and at larger text sizes. • SSH now uses the background transition time allowed by iOS, without requesting location to stay active in the background. • Clearer privacy information explains private iCloud, optional community sharing and consented requests to your chosen cloud AI provider. Measurement availability depends on the platform, network and paired devices. Measured throughput alone is not a Wi-Fi radio measurement or proof of CPU throttling.

Find what slows your network • New: Optimize My Network. A read-only copilot measures your router, DNS and Internet for about 15 seconds, shows where the connection degrades first and how sure it is. It changes nothing on your network. • Change band or room, then compare before and after on every measure, and check later that the gain holds. • DNS security: whether your DNS rejects forged answers (DNSSEC), hides its version and blocks trackers, and when results come from a VPN's DNS. • Optional, read-only: firmware, DNSSEC, Wi-Fi security and settings drift from OPNsense and UniFi; service loops and network posture from paired 404 sensors. • "Diagnose my network" with Siri and Shortcuts, a Control Center control, past diagnoses in Spotlight, and an automatic check when you join Wi-Fi. • iPhone: Wi-Fi details work again, and a switch between access points during a test is detected. • Widgets are translated, German now says WLAN, and pings no longer crash when stopped.

Small fixes and stability improvements. If 404 helps you find what's missing on your network, a short App Store review makes a big difference. Thank you!

Ready for iPhone Duo • On iPhone Duo, 404 uses both displays: side bars on the outer display, a wider dashboard and the whole toolbox on the inner display. • Measurements keep running when you fold or unfold. • Text follows your preferred text size throughout the app. • The dashboard summary now always matches the score on screen, in your language. • Right-to-left layout and French wording fixes.

Connect your 404 apps • A new Devices screen connects 404 on iPhone, iPad and Mac using reciprocal invitations and certificate-pinned TLS. • Measure received application bytes and round-trip latency, including latency under load. Review the data budget before starting. • Compare HTTPS diagnostics, save reports locally and export measurement campaigns. • Control an iPhone measurement from Apple Watch and receive progress and completion feedback. • French translations, clearer accessibility labels and connection reliability improvements. Keep both apps open for device-to-device tests. These measurements describe the tested path; they do not measure IP packet loss.

Monitoring, rebuilt - A new Monitoring tab answers in one sentence, then groups services by who checks them: this device or each of your sensors. Connection and freshness are shown once per sensor, so a disconnected sensor never reads as a service outage. - Per-service pages with 1 h / 24 h / 7 d / 30 d statistics, a latency chart that shows gaps instead of inventing data, per-source comparison, full history and a "Test from this device" button. - 24-hour availability strips and latency sparklines on the dashboard. - Notifications per service: in-app, system, sound, recovery and degradation alerts, confirmation count, quiet period, webhooks. - Pause, run now and delete monitors that run on a 404 sensor, applied only after the sensor confirms. Discovery - Connect OPNsense, MikroTik or UniFi (read-only) to name every device and see devices on other VLANs from DHCP leases. - Clearer map and legend, one entry per device instead of one per address, and a health summary in your language. Security and privacy - Sensors and the app now prove the pairing code to each other, and the connection is bound to the sensor's certificate. - The AI assistant asks before any active probe, never targets public addresses with them, and sends nothing to a cloud AI without your consent. - Router certificates must be approved before credentials are sent; API tokens and webhook URLs are stored in the Keychain. - Many reliability fixes: checks that could hang, pings that never ended, parsers hardened against malformed replies.

This update improves sensor reliability and makes sensor data easier to understand. • More reliable simultaneous sensor connections and reconnection after interruptions. • Network history now shows separate receive and transmit rates, with gaps when measurements are missing. • Fixed access to sensors from the iPhone dashboard. • Clear connection states and the time of the last received telemetry.

• Pro+ subscription can be purchased again — the paywall now asks the App Store for the right product IDs (it previously showed "not available"). • AI Assistant: updated to the current Claude model. A valid key no longer fails with "HTTP 404"; if a model is ever retired again the app retries with a fallback and explains the error. • Sensors: download links fixed (lorislab.fr/sensor), macOS Apple Silicon binary added, dead Homebrew/Docker instructions removed. • Remote sensors are a Pro feature — the app now says so and gates it consistently. • Purchase buttons are disabled with a clear message when the App Store returns no product, instead of failing on tap.

• Hybrid uptime monitoring: watch HTTP, TCP, ping and DNS endpoints from your device — with alerts, history and graphs. • New security assessment workspaces (Exposure Map, Web & API, Continuous Intrusion, Host & Supply Chain, Authorized Lab) that organize findings from authorized scans run on a paired companion sensor. • Scheduled speed-test logging with trends. • Clearer BETA labels on best-effort tools. • Apple Watch icon fix and many refinements.

• Redesigned local network discovery on Mac — clearer device map and inspector • Sharper, more readable colors and improved accessibility across the app • More reliable monitoring: no more false "offline" alerts when your own connection drops • SSH terminal now auto-reconnects when you switch between Wi-Fi and cellular • Faster, steadier history and settings screens • Numerous fixes, polish, and stability improvements

• Modern Discovery UI with Design Award-quality visual hierarchy • Enhanced topology map with distance estimation and smart clustering • Improved device filtering and batch operations • Refined network visualization with better color coding • Performance improvements and bug fixes

Connection Health 2.0 • WiFi vs Cellular comparison - test both networks separately • Expandable detailed results with raw timing data, network path info, DNS details, and connection info • Visual charts for timing breakdown, DNS comparison, and VPN analysis • Enhanced AI analysis with comprehensive network health verdict • Dashboard cards now link directly to Connection Health tool • Bug fixes and performance improvements

v1.4 — Better router integration + bug fixes Smarter router connection • Specific error messages when DHCP fetch fails — "auth failed", "2FA required", "endpoint not found", "TLS error", "timeout" — instead of the old generic "Connection failed". • UniFi UDM / Cloud Key: new "Use API Key" toggle. Settings → Admins → API Keys on your UDM, paste here, skips 2FA entirely. Recommended over user/pass. • UniFi: rewritten auth flow handling UniFi OS (UDM, UDM-Pro, Cloud Key Gen 2+) with CSRF token forwarding, plus legacy controller fallback. Bug fixes • Pro+ Annual paywall showed "Save 0%" in some locales — now correctly shows the actual savings vs monthly (16% on the current pricing). • AI Assistant unreachable — added the missing "AI Providers" entry under Settings so you can configure Claude / OpenAI keys (or use on-device models). • Developer mode unlock didn't update the UI immediately — Pro+ tier and multi-session terminal now activate right away. Tested 24 regression tests (savings calc, hostname priority, UniFi auth orchestration with mock controller responses) lock these fixes against future regressions.

v1.3 — Persistent terminal sessions • Lock your iPhone, switch apps, come back — your SSH shell keeps running. Server-side tmux auto-attach + iOS background runtime keep htop, apt upgrade, and tail -f alive. • One-tap tmux install on hosts that don't have it (Debian/Ubuntu/RHEL/Alpine/Arch/macOS detection). • Auto-reconnect when the app returns to the foreground. Smarter network discovery • DHCP-only devices now appear in scan results with a "DHCP" badge — printers, NAS, anything your router knows about even when offline. • Real DHCP names override reverse-DNS junk (Camera-G100 stays Camera-G100). • Explicit "Save & Test" in Router config — no more "did it save?". AI assistant that actually reads the terminal • Sees the last 5 command outputs, not just command names. Ask "what's going on?" mid-apt-upgrade and get a real answer. • Keyboard no longer hides the chat input. Cleaner sensor pairing • New status pill in the Dashboard toolbar (green when connected, grey when no sensor). • Settings → Sensors gives a clear empty-state and pair flow. • Removed the floating banner that leaked over keyboards and sheets.

Polish update: full localization in 7 languages (German, Spanish, French, Japanese, Korean, Brazilian Portuguese, Simplified Chinese), tighter store metadata, and internal cleanups for the upcoming Pro+ subscription launch.

Terminal improvements: • SSH key auth now works reliably — fixes parsing of OpenSSH Ed25519 keys imported from iCloud • Terminal content no longer ghosts or fades when the keyboard opens • Top bar stays pinned — no more vertical bouncing • AI Assistant: quick commands for sensors/temp, fans, GPU, kernel — it now replies with an executable command instead of a description

NEW: AI-powered SSH terminal with chat assistant, agent mode, and command suggestions. Improved key management with passphrase support and file import. Quick command answers for storage, RAM, CPU, docker, and more. Auto-summarize terminal output. Bug fixes and performance improvements.

Multi-Vantage Monitoring • Deploy sensors on Linux, Windows, or Docker to monitor your network from multiple vantage points • Watch tab now shows expandable multi-source rows with per-sensor sparklines and status • Sensor health dashboard with RTT, CPU, memory, and connection status CVE Vulnerability Scanner • Automatic CVE detection for discovered network devices • 21,000+ vulnerabilities from the NIST NVD database • Severity badges (CRITICAL/HIGH/MEDIUM/LOW) on discovered devices • Network risk summary bar with expandable device breakdown • Local push notifications for critical vulnerabilities Persistence & Reliability • Watch targets and check results now persist across app restarts • Background refresh checks for stale vulnerability data Every Device is a Sensor • Your iPhone and Mac running 404 can now act as sensors for each other • Bidirectional monitoring — check your network from any vantage point Bug Fixes • Fixed keyboard showing comma instead of period for IP input on French locale • Fixed peer connection bar overlapping tab bar • Improved sensor ping speed (port 80 first instead of port 7)
