Klox — The Network Toolkit for Professionals & Enthusiasts

Klox puts 14 powerful network utilities, real-time network intelligence, and device discovery right in your pocket. Whether you're an IT professional diagnosing connectivity issues, a developer testing APIs, or a privacy-conscious user wanting deeper insight into your network — Klox has you covered.

NETWORK INTELLIGENCE View detailed, real-time information about your connection at a glance: • Default gateway, DNS servers, and external IP (IPv4 & IPv6) • Wi-Fi details: SSID, BSSID, local IP, subnet mask • Cellular network type and addresses (LTE, 5G, and more) • Bluetooth device status • One-tap copy for any value

LAN DEVICE SCANNER Discover every device on your local network: • Real-time scanning with progress tracking • Reverse DNS resolution for device names • Mark devices as Trusted, Untrusted, or Unknown • Filter and organize discovered devices

AD BLOCKER Block ads and trackers — your way: • On-device mode: filters ad and tracker domains locally using on-device DNS — nothing leaves your phone • Advanced mode (optional, free): sign in to turn on system-wide filtering through our managed filtering service — pause or turn off anytime • Manage your block list: add your own domains or remove built-in entries, with search and history • Live dashboard: blocked queries, block rate, and total domains

PROFESSIONAL NETWORK TOOLS • Ping — Test host reachability and latency with color-coded results • Traceroute — Map the network path to any destination, hop by hop • DNS Lookup — Query A, AAAA, CNAME, MX, NS, SOA, TXT, and SRV records • Secure DNS — Encrypt DNS lookups with DoH or DoT. Use Cloudflare, Google, Quad9, AdGuard, or a custom endpoint. Affects DNS only; enable or remove anytime • Port Scanner — Scan open ports using presets or custom ranges • Whois — Look up domain registration, ownership, and expiry • WebRequest — Full HTTP client: GET, POST, PUT, PATCH, DELETE with custom headers and body • Device Info — Hardware report: processor, RAM, storage, battery, display, thermal state, and more • SFTP Browser — Browse and transfer files on remote servers via SSH. No credentials stored — data cleared from memory after each session • File Share — Start a local Wi-Fi file server with one tap. Auto-generated credentials, accessible from any browser on your network • Bluetooth Scanner — Detect nearby devices, view signal strength (RSSI), and manage trust levels • NFC Reader — Read NFC tags and NDEF records (ISO 14443, FeliCa, ISO 7816)

PI-HOLE MANAGEMENT • Add multiple Pi-hole v6 instances • Real-time stats: total queries, blocked count, block rate • Enable or temporarily disable blocking with custom timers • Point your encrypted DNS (DoH/DoT) at your own Pi-hole

THEMEABLE INTERFACE Choose from 6 handcrafted themes — 3 dark (Void, Night, Obsidian) and 3 light (Arctic, Mist, Canvas).

PRIVACY FIRST • No account needed for the core tools — an optional, free account enables advanced system-wide filtering • No credentials stored (SFTP data cleared after use) • No ads, no ad networks, and no cross-app tracking (no IDFA) • On-device ad blocking stays on your device — filtered locally • Diagnostic tools run locally or connect directly to the target you choose
