Core features

One tap from insight to action

Pick a feature to see exactly what it does. Every result is generated on your phone — nothing is uploaded to a server.

Know how safe your network really is

An on-device rule engine inspects your connected network and surrounding WiFi, then produces a single 0–100 security score with a clear grade and the exact issues to fix.

  • Flags open networks, WPS-enabled routers & legacy WEP/WPA
  • Prioritized, plain-language recommendations
  • Run an audit, then share the report card

Measure your true internet speed

One tap runs a full download, upload, ping and jitter test against Cloudflare's global edge network, with a live gauge and results saved to history.

  • Real throughput, not an estimate
  • Download, upload, latency & jitter in one run
  • Compare results over time in History

The full toolkit

Thirteen tools, one download

From quick scans to deep diagnostics — here's everything WiFi Analyzer puts at your fingertips.

WiFi Scanner

Discover every nearby network with SSID, BSSID, signal, frequency, channel, security type, WPS status and router vendor.

WPS Checker

Detect routers with WPS enabled and flag those exposed to known WPS security weaknesses, with a clear risk score.

LAN Scanner

Map every device on your local network — IP, MAC, hostname, vendor and a trusted/unknown label to spot intruders.

WiFi Vault

Save your own WiFi keys to an AES-256 encrypted local vault and share them as QR codes. Never uploaded anywhere.

QR Code Sharing

Generate a QR code for any network so guests can join instantly — created on-device and shared only when you choose.

DNS Lookup

Resolve any domain to its IP records through public resolvers — quick diagnostics and a great way to learn how DNS works.

SSL Inspector

Connect to any host and inspect its TLS certificate — issuer, validity dates and trust chain, explained simply.

Port Scanner Authorized use

Probe open ports on hosts you own or are authorized to test — for legitimate network diagnostics and learning.

FAQ

Questions, answered

Yes — for educational, diagnostic and authorized use on networks, routers and devices you own or have explicit permission to test. Using it to access networks you don't own is strictly prohibited. See our Acceptable Use Policy and Terms of Use.
No. WiFi scans, security reports, LAN data, history and saved passwords are processed and stored only on your device. The Speed Test connects to Cloudflare's public servers, and the DNS Lookup / SSL Inspector contact the hosts you enter — but we operate no servers that store your personal data. Full detail is in the Privacy Policy.
Never. There are no sign-ups, logins or cloud profiles. Install the app and start scanning.
Android requires location permission before any app can read WiFi scan results (including SSID and BSSID). WiFi Analyzer uses it only to enable scanning — never for GPS tracking or background location. You can revoke it anytime; only the scanning features stop working. See Privacy Policy § App Permissions.
Yes. Credentials saved in the WiFi Vault are encrypted with AES-256 in a local database and are never transmitted, uploaded or shared. They stay on your device until you delete them.
Most tools — WiFi Scanner, WPS Checker, Channel Analyzer, LAN Scanner, WiFi Vault and Academy — work fully offline. The Speed Test, DNS Lookup and SSL Inspector need an active connection because they reach external services.
PRO removes all ads and unlocks premium features like deep WPS scanning, new-device alerts and full history. It's available as a monthly subscription (with a 3-day free trial) or a one-time lifetime purchase via Google Play Billing. The exact price is shown in your local currency in Google Play. You can cancel anytime from Google Play, and refunds are handled by Google. Details in the Subscription & Refund Policy.
It measures real throughput against Cloudflare's edge network, so results reflect your actual connection — they'll vary with congestion, hardware and signal quality. A full test can transfer roughly 50–150 MB, so avoid running it on limited or metered data plans.
