About this app

Is your WiFi slow, unstable, or dropping out? Wifi Analyzer helps you find out why — and fix it. See every WiFi network around you, find the right channel for your router, test your internet and local network speed, and diagnose problems with professional network tools. Whether you're setting up a new router, optimizing coverage in your home, or troubleshooting at work, this app has you covered. Trusted by over 1 million users worldwide.

🔍 WiFi Signal Overview
View all nearby WiFi networks on an interactive real-time signal graph. See signal strength, channel overlap, and interference at a glance. Switch between 2.4 GHz, 5 GHz, and 6 GHz views. Tap any network for full details including encryption, channel width, WiFi standard, and router manufacturer.

📊 Channel Recommendation
Not sure which channel to use? The wifi analyzer recommends the optimal channel by scanning all detected networks, calculating interference scores, and showing you exactly which channel will give optimal performance — for both new and existing access points.

⚡ Speed Testing
Internet Speed Test — measure your ping, download speed, and upload speed against worldwide servers. Results appear in real time with a clean 3-column display.
WiFi Speed Test — measure the actual throughput between your phone and your router over your local network. Great for checking if your WiFi link is the bottleneck.

🗺️ WiFi Heat Map
Upload your floor plan, walk around, and tap to measure. The app builds a color-coded signal map showing exactly where your coverage is strong, weak, or dead. Essential for placing routers, extenders, or access points.

🛠️ Network Tools
Eight professional diagnostic tools built right in:
Ping — latency measurement with jitter and packet loss analysis
Traceroute — hop-by-hop path visualization to any destination
DNS Lookup — full record query (A, AAAA, MX, NS, TXT) with SPF, DKIM, DMARC mail security audit and rating
Port Scanner — scan port ranges, identify open services, security warnings
Whois — domain registration, registrar, expiry, nameservers
LAN Scanner — discover all devices on your network with MAC address and vendor identification
SSL Certificate — full certificate chain inspection, TLS version, cipher analysis, security grade A+ to F
Network Info — complete overview of your connection: IPs, gateway, DNS, DHCP, WiFi standard, public IP

📈 Signal History
Track signal strength changes over time. Move around and watch the graph update live. Useful for finding the ideal placement for your router or workstation.

📋 WiFi List
Sortable, filterable list of all detected networks. Sort by signal quality, name, or interference. Filter by channel — tap a channel on the overview graph to instantly see only networks on that channel.

🔒 Privacy
Location permission is required by Android for WiFi scanning — the app does not store or transmit your location.

Ratings and reviews

Heat map does not allow me to take photo. It doesn't even ask for storage or camera permissions, and that option is not present in the app info page. Only permission it asks for is "location." So, when i click "take photo," it just goes back to the grid. Nothing happens. Otherwise, it's full of useful and effective tools. But the heat map function is what would really set it apart.

Heatmap is the big draw here. Camera icon does nothing. you are not even able to set the camera manually. Edit based on dev reply: I would like to see the camera app functional, especially with the button there. the app is otherwise excellent. I've bumped my rating up, to be fair and honest with this dev. I'll go up more with the camera. wink wink, nudge nudge

Mainly using it to assess Wi-Fi signal interference around me and see what channel might be better - so far it's worked pretty well. I'm not sure why they removed the channel recommendation for existing AP? 99% of the time I'm looking at my existing router. Would be nice if you could save a record of some current data points for comparison purposes next time you scan.
