What’s new in 2.20.0: • Threats: “What to do” now opens clear steps for each finding, and the header count matches the list • Fewer false alarms: WPA2 networks no longer read as open, and a router is no longer flagged just because it switched band • IoT check now probes camera, Telnet and DVR ports, and UPnP on your router is detected correctly • Signal analyzer: hourly history, roaming support (802.11k/v/r) and session export • Fixed a crash at launch on some devices
Find devices on your WiFi, detect risks, test speed and improve signal.
Know what is connected to your WiFi — and what needs your attention. Wifi Guard helps you understand and secure the Wi‑Fi you use every day — at home, at work, or on public hotspots. See who is on your network, spot risky Wi‑Fi setups, and get clear tips before signing in to sensitive accounts. KEY FEATURES • Nearby Wi‑Fi scanner Check encryption (Open / WEP / WPA / WPA2 / WPA3), channel, band, signal strength, and vendor info. • Threat scan Look for common risks such as evil-twin lookalikes, weak or open Wi‑Fi, captive portals, WPS exposure, DNS concerns, and more. Scans focus on your current network. Export reports as text, CSV, JSON, or PDF. • Devices on your LAN Discover phones, computers, TVs, cameras, and IoT devices. See open ports with plain-language tips, mark favorites, and get alerts for new devices. • Network health & security checklist Security score, combined signal & channel advice, and a practical checklist for every network profile (home, work, guest, and more). • Speed test Measure download, upload, ping, and jitter. Keep history and compare Wi‑Fi vs mobile data. • Signal tools Live signal analyzer, channel recommendations, coverage / dead-zone testing, and signal heatmap. • Extra tools Network topology map, ping tool, Deauth Alert, WPS audit (advisory), DNS / Private DNS helpers, notification rules, and a compact home-screen widget that follows your in-app language. • Made for many languages English, Turkish, German, Spanish, Portuguese (Brazil), French, Russian, Arabic, Hindi, Indonesian, Vietnamese, Chinese, Japanese, Korean, Italian, Polish, Bengali, Urdu, Thai, Malay, and more. WHO IT’S FOR Home users who want to know who’s on their Wi‑Fi, travelers on hotel or café networks, and anyone who wants a clearer view of network security — without a networking degree. PRIVACY Network analysis runs on your device. Wifi Guard does not upload your device inventory and does not collect or share personal data. No account is required. See the in-app privacy policy for details. Some features reach beyond your network: the speed test transfers data with the provider you choose, and the optional IP Lookup tool queries ip-api.com. IMPORTANT Wifi Guard does not hack networks or crack passwords. It analyzes information available to your phone to help you make safer choices. Results can vary by Android version and router settings. Download Wifi Guard and take a clearer look at your Wi‑Fi.
