Wireless Monitor

Cellular, Wi-Fi, Bluetooth and magnetic field — the actual numbers

Wireless Monitor is coming to Google Play.

What it does

Four radios, in real units

Cellular RSRP in dBm with network type, carrier and band. Wi-Fi RSSI, channel and link speed, plus a scan of nearby access points. Bluetooth Classic and BLE listed separately. The magnetometer's reading in microteslas. The same numbers your phone uses internally, not bars.

Labeled snapshots you can compare

Save a reading where you are standing — "Living room", "Behind the fridge" — then compare spots side by side to find out which one actually has the better signal.

History and CSV export

A timeline per module shows how a signal changed over the day, and any log can be exported to CSV through the share sheet.

Nothing leaves the phone

No backend, no account, no analytics SDK, no ads. Optional GPS tags on snapshots are written to the same local database as the reading and never leave your device.

Honest measurements, no health claims

The app reports what the radios and sensors report, and nothing more. It computes no exposure level or safety score, and the magnetometer reads static and low-frequency magnetic fields only — it is not an RF sensor.

Seven-day trial, one-time unlock

The whole app is free for seven days. After that a single in-app purchase unlocks it permanently — no subscription, no recurring charge, no ads.
