WiFi Meter: Signal Analyzer

Is it your Wi-Fi or your internet provider? WiFi Meter tells you in seconds, then helps you fix it.

Measure your signal, find dead spots, pick the clearest channel, map coverage room by room and see every device on your network. Readings are an easy percentage, or dBm if you prefer the numbers engineers use. No ads, no account, no tracking.

SIGNAL METER
• Live gauge with signal strength, link speed, band, channel and Wi-Fi standard (Wi-Fi 4 to 7)
• Signal trace for the last minute, or the last 30 minutes (Pro)
• Locate mode: pulses speed up as the signal gets stronger, by sound or vibration
• Home-screen widget with your signal at a glance (Pro)

WI-FI OR PROVIDER?
• Ping monitor graphs your router and the internet side by side and says where lag comes from
• Speed test: download, upload, latency and router ping
• DNS and website check spots slow or broken DNS
• Scheduled speed tests build a history you can export as evidence for your provider (Pro)
• Local link test against your own iperf3 server measures your Wi-Fi alone (Pro)

NETWORKS AND CHANNELS
• Every nearby network on a radar and in a list, with security, channel width, Wi-Fi standard and router maker
• Channel graph for 2.4, 5 and 6 GHz and the clearest channel for your router, with DFS channels marked
• Compare the access points of a mesh or extender, with plain advice when another one or another band would be better
• Track any network you're not connected to, like a new extender you're placing (Pro)
• Roaming test checks that your phone switches mesh access points in time (Pro)

DEVICES
• See which devices are on your Wi-Fi, with names and types
• A history of which devices joined and left, and when
• Get an alert when a new device joins (Pro)

SURVEYS AND COVERAGE MAPS
• Measure room by room and spot weak areas
• Add your floor plan and see a coverage heat map (Pro)
• Share a PDF report or export to CSV (Pro)

ALERTS AND HISTORY (Pro)
• Notifications when the signal gets weak, the connection drops or your phone switches access point
• Connection log with every drop and weak spell, and a 24-hour signal chart

HELP IN PLAIN WORDS
• Tap the (i) next to a reading for a short explanation
• In English, Spanish, German, French and Portuguese

PRIVATE BY DESIGN
• Measurements, surveys, device scans and settings stay on your phone
• Android requires location permission for Wi-Fi scans. WiFi Meter uses it only for that and never reads your GPS position.
• The app only goes online when you run a test: the speed test uses Cloudflare, and the DNS check contacts Google, YouTube, Wikipedia and Cloudflare

WIFI METER PRO
One payment, no subscription, unlocks everything marked (Pro). Everything else is free, with no ads.

Good to know: Android limits how often apps can scan for Wi-Fi (4 scans every 2 minutes on Android 9 and newer), so the networks list refreshes about every 30 seconds unless you turn off "Wi-Fi scan throttling" in Developer options. The signal of the network you're connected to updates every second.

Light and dark themes, works on Android 7.0 and newer. Questions or ideas? Write to apps@realmbit.com.
