Magnetometer+ turns your iPhone into a precise magnetic field meter with three purpose-built modes — and now keeps a full history of every reading. THREE MODES • Auto — radial gauge with raw total field magnitude. • Earth Field — total field with latitude band (low / normal / elevated / high). • Metal Detector — baseline-calibrated detection with intensity verdict (no metal / weak / detected / strong / large) and live haptic feedback. WHAT'S NEW • ⌖ Zero Calibration — capture your environment's device-internal field bias as the 0 reference, so subsequent readings show only deviation. Just like a real metal detector. • Haptic Feedback — Metal mode pulses faster and stronger as you approach ferrous objects. Toggle on/off from main screen. • Unit Toggle — switch between µT, mT and Gauss with a single tap. • GPS Tagging — optionally tag saved measurements with location coordinates. • Measurement History — every reading is auto-saved with a 7-day trend chart and insights like "+12% vs your 7-day average". • Notes & Favorites — add a note ("wall stud", "buried pipe") and star to any saved reading. • Compare Mode — pick two saved readings and view the difference side by side. • Share Result — share your current reading as an image. • CSV Export — share all your measurements as CSV for spreadsheets. CORE FEATURES • Real-time 3-axis magnetic field measurement • Kalman-smoothed sensor readings • Min/Max/Avg/Peak tracking with elapsed time • Sensitivity adjustment 0.5x – 2.0x • Total field magnitude + per-axis components • Reference library: Earth field bands, metal intensity classes HONEST TECH NOTE iPhone magnetometers are uncalibrated and include device-internal bias (~300–450 µT from speaker / motor / battery magnets). The ⌖ Zero button captures that bias so subsequent readings reflect only field changes in your environment — same workflow as a physical metal detector.

Verdict

The call

The clearest difference is ads: NGS at none against Magnetometer+'s shown. NGS also leads on device support (3 vs 1). Magnetometer+'s advantage is update cadence (every 4 days vs every 23 months). On price, in-app purchases and iOS requirement there is nothing between them.
