netscope

NetScope is a pocket-sized network engineer's toolkit. It tells you, in seconds, whether your internet is healthy — and if not, where the problem is. No accounts. No cloud sync. No background tracking. Open the app, tap "Run full diagnostic", and read the answer. ━━━ WHAT YOU CAN DO ━━━ • SPEED TEST — Measure download, upload, ping and jitter against major public endpoints (Cloudflare, OVH, Linode). Results land within ±10 % of Ookla on the same link. Live gauge, ping waveform, sparklines of your last 10 runs. • NETWORK SANITY — A composite A–F health grade built from eight vitals: latency, jitter, packet loss, DNS lookup time, download, upload, IPv6 reachability, and MTU. Designed so a non-technical user can answer "is my internet OK right now?" in one glance. • WHOAMI — Your public IPv4 / IPv6, ISP, ASN, geographic city/country, reverse-DNS hostname, VPN / proxy flag, plus local network info (SSID, RSSI, channel, MTU). Tap any row to copy. • DNS LOOKUP — Resolve A, AAAA, MX, NS, TXT and CNAME records for any domain via Cloudflare's DNS-over-HTTPS resolver. Per-record TTL and MX priority. • TRACEROUTE — See every hop your traffic takes to a target. Per-hop hostname, IP, ASN and latency. Uses UDP-TTL probes so it works without root. • LOCAL NETWORK SCANNER — Discover devices on your Wi-Fi: IP, MAC, hostname, vendor (OUI lookup), and open ports for quick service hints. • BLUETOOTH SCANNER — Live list of nearby Bluetooth Low Energy advertisements: name, MAC / rotating identifier, RSSI, advertised services, manufacturer data. Tap a device for the raw advertisement and RSSI history. • UNKNOWN-TRACKER SCANNER — Detects nearby Bluetooth trackers (AirTag-class, Tile, SmartTag, Chipolo). Flags persistent unknown trackers that may be moving with you. Scanning is 100 % local — nothing about other devices ever leaves your phone. • HISTORY — Every test you run is saved locally with timestamp, network, numbers and grade. Swipe to delete. Clear-all in one tap. ━━━ DESIGNED FOR ━━━ ✓ Home users who want to prove the Wi-Fi (or the ISP) is the problem. ✓ Remote workers checking hotel / café connectivity before a call. ✓ Mobile developers, SREs and IT pros who want pocket-grade diagnostics without SSHing into a box. ✓ Anyone curious about what's actually on their local network. ━━━ PRIVACY FIRST ━━━ • No account, no sign-in, no profile. • No cross-device sync. Your test history lives on this phone only. • No third-party analytics SDKs. No behavioural tracking. • Speed-test traffic goes only to the well-known measurement endpoints we list (Cloudflare, OVH, Linode) and your chosen public-IP lookup. • Bluetooth scanning is local. Tracker scanning is local. • Ads are served by Google AdMob and respect your system-level ad-tracking settings. You can opt out of personalised ads from inside the app. Full privacy policy: see the link in the Play Store listing. ━━━ ENGINEERING-INSTRUMENT UI ━━━ NetScope deliberately looks like a piece of test equipment: monospaced numerals, tabular figures, crosshair tick marks, radar / oscilloscope visualisations, dark theme by default with a light theme available. Pick from four accent palettes (signal, cyan, amber, magenta) and three density presets. ━━━ PERMISSIONS, EXPLAINED ━━━ • INTERNET / NETWORK STATE — required to run the speed test, DNS, whoami and traceroute. • Wi-Fi state / location (when the OS requires it) — only used to read your current SSID, RSSI and channel. We never request background location. • Bluetooth scan / connect — only used while you're on the Bluetooth or Tracker screen. Foreground only. • Vibration - short haptic feedback on test completion. Built with React Native / Expo. Single codebase, fully native networking on Android.
