## What is Metal Detector?

Find hidden screws, nails and steel objects with your iPhone's built-in magnetometer. IronScope shows the live magnetic field in µT and beeps faster as you get closer. Works fully offline — no ads, no account.

WHAT IT FINDS
• Steel screws and nails behind drywall (a quick way to locate where a stud is fastened)
• Iron and steel objects, magnets and magnetic mounts at close range
• Changes in the magnetic field around electronics and accessories
IronScope detects ferromagnetic metal only. It cannot see wood, plastic, aluminum or copper, and it does not locate wooden studs directly — it finds the metal fasteners in them.

KEY FEATURES
• Real-time magnetic field reading in µT with a color-coded gauge
• Audio alert that speeds up near strong signals
• Scan Confidence card: sensor, baseline, signal and next step at a glance
• Works on iPhone and iPad models with a magnetometer
• Calibrated magnetometer readings (the system-calibrated field, not the phone’s raw sensor bias)
• Automatic baseline when you open the app, plus a figure-8 prompt if the sensor needs calibration

IRONSCOPE PRO
• Saved calibration to your local baseline
• Signal Marks: save up to 7 readings and recheck the same spot later
• Live signal history and 60 Hz high-precision sampling
• CSV export of your readings

HOW IT WORKS
The magnetometer reads the ambient field, often 25–65 µT from the Earth alone. IronScope compares the live reading with a baseline and shows the excess as signal strength. Readings vary by phone model, orientation, cases, magnets and nearby electronics.

LIMITATIONS
A phone magnetometer is not a professional metal detector. Range is a few centimeters. Do not use IronScope for security screening, mining, locating buried pipes or cables, or any safety decision.

PRIVACY
Readings are processed on your device. No location, audio, analytics, ads or tracking.

## Version history (last 5 releases)

### 1.1.0 — 2026-11-12

IronScope now uses your iPhone’s calibrated magnetometer, so the live reading shows the magnetic field rather than the phone’s own sensor bias. When you open the app, it can set a baseline automatically, and it may ask you to move the phone in a figure-8 if the sensor needs calibration.

Yearly Pro includes a 3-day free trial. This version also adds German, French, Spanish, Brazilian Portuguese, Swedish and Turkish, plus English (UK).

### 1.0.6 — 2026-06-20

IronScope now adds Scan Confidence, a clearer read on sensor availability, baseline quality, signal excess, sampling mode, and the next action before you trust a reading. The Pro paywall also includes a direct Support link, while calibration, CSV export, privacy boundaries, and subscription IDs stay intact.

### 1.0.5 — 2026-06-12

Added a clearer field guide on the main screen, with Earth-field reference range, calibration advice, and phone magnetometer limitations. This build also preserves existing calibration data and CSV export format.

### 1.0.4 — 2026-06-02

This update completes the English in-app experience and adds a clear fallback when a device or simulator does not provide magnetometer data. IronScope now explains that readings are phone magnetometer estimates and should not be used for security screening, mining, or safety decisions. The history, calibration, export, subscription flow, and StoreKit messages have also been refreshed. Existing subscriptions are preserved.

### 1.0.3 — 2026-05-07

Bug fixes and subscription review compliance improvements.
