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
