Turn your iPhone into a live magnetic-field meter. Watch the reading in microteslas (µT), follow changes in color and revisit your saved scans. Finish a basic or camera scan and save the result directly. Returning to the starting spot for a comparison is optional. Reopen the saved record without making a duplicate, compare two records, or share an image or CSV. Start measuring immediately. Set an optional starting value to follow changes in your surroundings, then use the live graph, color levels, adjustable alerts and haptics to explore the reading. IN VERSION 1.7.1 • Live magnetic-field reading and 60-second history • Adjustable change sensitivity, optional sound and haptic alerts • Starting-value and guided return comparisons • Optional Field Lens: approximate reading points over the camera view • Saved scans, two-scan comparison, image and CSV sharing • Light and dark appearance The meter works without camera access. Field Lens requires a compatible iPhone and camera permission. Camera frames and saved scan contents stay on your device unless you choose to share an export. KNOW THE LIMITS This is a magnetometer app. A changing reading does not identify a metal object, its type or depth. It cannot reliably find gold, silver or every kind of metal, and cannot establish whether drilling is safe. Magnetic cases, speakers, electronics and changes in phone position can affect readings. Camera points are approximate. Requires a magnetometer-equipped iPhone and iOS 17 or later. Free with banner ads; no subscription or account required. App interface: English, Turkish, Spanish, German, French, Brazilian Portuguese, Arabic and Japanese.
