WiFi Strength Meter & Analyzer

Weak WiFi is a solvable problem — if you can see it. WiFi Strength Meter is a complete toolkit for measuring, mapping and fixing your wireless network: live signal readings, real speed tests, a room-by-room coverage heatmap, channel analysis, security monitoring and connectivity tracking, all in one app.

KEY FEATURES

• Signal meter — live WiFi signal strength in dBm for your network and every network around you, with detail views per network
• Speed test — download, upload, ping and jitter, with a full history so you can prove whether your connection got better or worse
• WiFi heatmap — walk your home taking readings and build a coverage map that shows exactly where the signal dies
• Channel analyzer — see crowded channels and neighbor overlap, then move your router to a cleaner one
• Device scanner — list the devices connected to your network and spot ones you do not recognize
• Security scanner with evil twin alerts — get warned when a suspicious network imitates one you trust
• Trusted networks — mark your safe networks so alerts stay meaningful
• Connectivity monitor — background tracking of drops and outages, with daily stats and an outage history
• DNS test and router login shortcut for quick diagnostics and settings access
• WiFi password strength checker
• Network history with charts, plus practical WiFi guideline articles
• Dark mode, CSV and PDF export (premium), and notification alerts you control

AN HONEST NOTE

Signal readings come from your phone's WiFi hardware, so absolute values vary between devices — trends and comparisons are where the meter shines. The heatmap reflects the readings you take as you walk. Android requires the location permission for WiFi scanning; this app uses it for scanning and the features described here.

WHY CHOOSE WIFI STRENGTH METER

• Measurement, mapping, speed and security in ONE app instead of four
• The heatmap turns "the WiFi feels slow upstairs" into a picture you can act on
• Outage tracking gives you evidence for your ISP, not just a feeling
• Evil twin detection watches for a real and underrated WiFi attack
• Your scan data stays on your device, and premium exports it to CSV or PDF

PREMIUM

A premium upgrade removes ads, unlocks unlimited history and CSV/PDF export, shows every device the device scanner finds (the free version lists five) and opens every tool without an ad. The core meter, channel analyzer and speed test require no purchase.

PERFECT FOR

• Placing a router, mesh node or extender where it actually helps
• Renters and buyers checking coverage before committing to a home or office
• Gamers and remote workers hunting down lag, drops and dead zones
• Anyone who suspects their ISP is not delivering the promised speeds
• Privacy-conscious users watching for rogue access points and unknown devices

Map it, measure it, fix it — your WiFi has nowhere left to hide.
