Metal Detector S
Read full descriptionHide full description
features include: Real-Time Magnetic Field Detection: Displays magnetic field strength (in µT) with an intuitive level indicator. Vibration Alerts: Triggers vibration when magnetic field strength exceeds the threshold (device support required). Clean Interface: Modern design with start/stop detection and vibration control buttons for intuitive operation. Features Efficient Detection: Processes magnetometer data in real-time without storing or transmitting it, ensuring privacy. Customizable Experience: Toggle vibration on/off to suit different scenarios. Notes Detection Limitation: Only detects magnetic metals (e.g., iron, nickel); non-magnetic metals (e.g., aluminum, copper) are not detectable. Device Compatibility: Some devices may not support magnetometer or vibration functions. Please check your device’s compatibility. Download Metal Detector S now and experience convenient metal detection!

See the magnetic field. Find what others can't. NextMAG is a portable, passive magnetic sensing platform for industrial, utility, and defense teams. This app is its interactive showcase: six interactive demonstrations that let evaluators experience the platform's analysis engine with no hardware on hand. Everything runs on your device — no account, no login, no ads. SIX LIVE DEMONSTRATIONS - Spectral Monitor: a live magnetic field trace with a real FFT spectrum and scrolling spectrogram. Watch 50/60 Hz harmonics and EMI fingerprints resolve in real time. - Source Locator: invert a line of surface sensors to pinpoint a buried source's position and estimate its depth, with confidence. - Magnetic Camera: reconstruct the field over an area and localize a source in x, y, and depth — point sensors become an imager. - Live Tracking: a daisy-chained sensor mesh tracks a moving source in real time, with live and rolling error and confidence. - Predictive Maintenance: learn a machine's healthy magnetic signature, then catch bearing-fault drift early with a trend-based health score. - Live Space Weather: a high-cadence NOAA SWPC feed — Kp and G-scale, solar wind speed and density, IMF Bz, and live GOES X-ray flare class. HONEST ABOUT THE DATA Five of the six demonstrations run on synthetic magnetometer data generated on your device, clearly labeled "Simulated data" in the interface, so you can explore the full analysis pipeline — real FFTs, real inversion math, real health scoring — without hardware. The exception is Space Weather, which shows real, live conditions fetched read-only from NOAA's Space Weather Prediction Center. The app does not read your phone's sensors, and no data about you is collected or uploaded. BUILT FOR EVALUATORS Passive sensing and detection only. The platform monitors the magnetic field, fingerprints interference, and locates and tracks buried or moving sources — a quiet complement to RF and counter-UAS airspace defense. In production, the same software reads from deployed NextMAG magnetometer hardware; this showcase lets your team assess the analytics first. PRIVACY BY DESIGN - No account or sign-in - No ads, no analytics, no trackers - All demonstration processing happens on-device - The app's interface is served over HTTPS from the NextMAG origin - Its only data fetch is read-only public NOAA space-weather data Questions or an evaluation inquiry?

Verdict
The clearest difference is ads: NextMAG Intelligence Platform at none against Metal Detector S's shown. Metal Detector S's advantage is iOS requirement (13.0 vs 15.0). On price, update cadence, in-app purchases and device support there is nothing between them.
