MeterWorks Teslameter vs Magnet Meter

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.

Magnet Meter turns your iPhone's built-in magnetometer into a powerful magnetic field detector and metal finder. Sweep your phone over any surface and watch the live gauge, color heatmap, and audio tones react instantly as you close in on magnets, magnetized metal, and hidden magnetic anomalies. WHAT YOU CAN DO - Detector gauge: a big, easy-to-read radial meter shows magnetic field deviation in real time, with peak-hold so you never miss a spike. - Audio + haptic feedback: hear and feel the field get stronger, so you can scan without looking at the screen. - Axis view: see the raw X, Y, Z magnetic components and total field strength. - Waterfall: a scrolling history graph reveals how the field changes as you move. - Compass: a true-north compass that also shows how nearby metal bends the field. - AR Heatmap (Pro): paint magnetic field strength right into the space around you using your camera. WHAT IT FINDS Magnet Meter detects changes in the magnetic field. It is great for finding magnets, magnetized steel and iron, speaker magnets, hidden hardware, rebar, and magnetic studs. Because it measures magnetism, it does NOT detect copper pipes, aluminum, or live AC wiring. ZERO / CALIBRATE Tap Zero to capture the ambient field as your baseline, so only nearby objects register. A built-in calibration prompt helps keep readings on track. CUSTOMIZE - Multiple color maps and units (microtesla, gauss, milligauss) - Adjustable sensitivity - Clean, focused interface designed for one-handed sweeping MAGNET METER PRO A single one-time purchase (no subscription) unlocks the AR magnetic heatmap, CSV session export, a finer sensitivity floor, watermark-free sharing, and removes ads. Your purchase applies to your Apple ID across all your devices. IMPORTANT Magnet Meter is for educational and entertainment use only. Readings are relative and approximate and may be inaccurate. It is not a calibrated scientific or safety instrument: do not rely on it to locate live electrical wiring, gas lines, or any hazard. Requires a device with a magnetometer.
