WiFiGo vs MeterWorks Teslameter

Find dead zones, test network quality, and build Wi-Fi heatmaps from your iPhone or iPad. WiFiGo gives you a complete Wi-Fi toolkit for diagnosing weak coverage, unstable connections, and hidden network issues without cloud accounts or complicated setup. CREATE WI-FI HEATMAPS Import a floor plan or create one from scratch, then record signal readings room by room and watch a live heatmap build as you move. Perfect for finding dead zones, weak spots, and the best router or mesh placement. RUN REAL NETWORK TESTS Measure download speed, upload speed, ping, and jitter. Scan devices on your network, trace routes, check open ports, and review IP, DNS, and connection details in one place. UNDERSTAND WHAT’S WRONG WiFiGo turns raw network data into clear, practical insight so you can spot congestion, lag, poor coverage, and unstable performance faster. EXPORT CLEAR REPORTS Save and share polished reports for your home, office, landlord, ISP, clients, or IT team. BUILT FOR PRIVACY No cloud account required. Your scans, plans, notes, and reports stay on your device unless you choose to export them. GREAT FOR Homeowners, gamers, creators, installers, property managers, and IT professionals who want better Wi-Fi visibility without enterprise complexity. Upgrade to WiFiGo Pro for advanced heatmapping, deeper diagnostics, unlimited history, comparisons, and richer exports.

Your iPhone has a real magnetic field sensor — this app turns it into an honest instrument. No ghost detector, no ads covering the reading, no subscription: MeterWorks Teslameter measures, records, and documents magnetic fields. MEASURE • Live field strength |B| with a big readout and a smooth real-time graph • All three axes plus magnitude, 100 Hz sampling, µT or mG • Zero baseline: blank out the ambient field and hunt magnets and metal in delta mode • Compass calibration state shown honestly RECORD & ANALYZE • Recordings with key metrics: RMS, peak, peak-to-peak, crest factor • Zoom, pan, and cursor in the recording graph — stats for the visible range • Pro: FFT spectrum with peak list and AC field indicator (50 Hz mains hum, beta) YOUR DATA IS YOURS • Free: PNG export of all four channels • Pro: clean CSV export of the full raw series — spreadsheet-ready • Pro: multi-page PDF report with statistics matrix, time series, spectra, and measurement documentation FREE VS. PRO — NO SURPRISES Free is a real instrument: unlimited live measurement, three recordings of 10 seconds each, full metrics, PNG export. Pro is a single one-time purchase: unlimited recordings, FFT analysis, CSV and PDF export — all future Pro features included. No subscription, ever. WHAT THIS APP CANNOT DO — HONESTLY The magnetometer measures static and low-frequency magnetic fields up to 50 Hz (the Nyquist limit of 100 Hz sampling). Radio frequency — cellular, Wi-Fi, Bluetooth — is beyond ANY smartphone magnetometer; apps promising "radiation readings" are bluffing. This is not a wire detector either: always use a proper scanner before drilling. The in-app page "Limits of this measurement" explains exactly what works. TYPICAL USES Locate magnets and magnetic metal · compare speaker and magnet field strength · check low-frequency EMF indicatively · show Earth's field (physics class) NO SUBSCRIPTION. NO ADS. NO TRACKERS. All measurement data stays on your device. EMF put honestly in context: facts, not fear. MeterWorks is a family of honest measurement apps: Vibrometer for vibration, Sound Meter for your noise log — just as honest, just as subscription-free.
