Metal Detector・EMF Reader vs Gear Design Master

Turn your iPhone into a powerful Metal Detector, Stud Finder & EMF Reader using the built-in magnetometer sensor. Metal Detector helps you locate nearby metal objects, detect magnetic fields, analyze EMF levels, and visualize live magnetometer readings directly from your device. Whether you’re searching for hidden metal, locating wall studs, checking electronics for EMF activity, or exploring magnetic fields around you, this app gives you real-time precision and easy-to-read insights. Perfect for DIY projects, construction work, home improvement, electronics testing, hobby exploration, and everyday utility use. FEATURES • Detect nearby metal objects using your iPhone’s magnetometer • Find wall studs, screws, nails, pipes, and hidden metallic objects • Real-time magnetic field readings in microtesla (µT) • Live EMF meter and magnetometer graph visualization • Signal confidence indicator for stronger detections • Axis-based directional detection system • Smooth real-time graphing of magnetic field activity • Minimal, clean, and professional interface • Fast and lightweight performance • Works instantly with supported iPhones HOW IT WORKS The app uses your iPhone’s built-in magnetometer sensor to measure magnetic field strength. When metal or magnetic objects are nearby, the magnetic field changes and the app displays the variation in real time. You can use Metal Detector to: • Locate metal studs in walls • Find hidden screws or nails • Detect magnetic interference • Measure EMF activity around electronics • Explore magnets and magnetic fields • Scan objects for metallic presence GREAT FOR • DIY & home improvement • Construction & renovation • Electricians & technicians • Hobbyists & explorers • Educational science experiments • Everyday utility detection IMPORTANT NOTES • Accuracy depends on your iPhone’s magnetometer sensor • Best results occur with ferromagnetic metals like iron and steel • Does not work for non ferrous metal like Aluminum, gold, silver • Thick walls or heavy interference can affect readings • Remove magnetic phone accessories for improved accuracy Download Metal Detector today and transform your iPhone into a smart magnetic field scanner, EMF reader, and stud finder tool.

Gear Master is an engineering workspace for mechanical designers, manufacturing engineers, inspectors, and maintenance teams. It connects design targets, geometry checks, candidate comparison, manufacturing preparation, and deliverables in one traceable workflow. GEAR PAIR DESIGN CHECK • External parallel-axis spur and helical gear pairs • Normal module, tooth counts, pressure and helix angles, face width, profile shifts, and backlash • Working pressure angle, center distance, pitch geometry, tooth thickness, base pitch, and contact ratios • Screening for theoretical undercut, tip thickness, continuous mesh, and geometry limits • Preliminary Lewis/Hertz strength screening from power, speed, application factor, accuracy grade, and materials RATIO & CENTER-DISTANCE SOLVER • Search by target ratio, center distance, envelope, module, tooth counts, and minimum contact ratio • Evaluate spur and several helical-angle strategies • Produce up to 40 deterministically ranked candidates • Explain scores, preferred modules, and rejection counts MANUFACTURING & INSPECTION • Base-tangent span tooth count and length • Normal chordal thickness and height, ideal pin, and selected-pin measurements over pins • Active-involute pin-contact validation, helical measurement-width limit, and lead • Preview complete closed nominal transverse involute profiles • Export millimetre-based ASCII R12 DXF, CSV data, and Markdown reports MATERIALS & PROJECTS • Grade-specific through-hardened, induction-hardened, case-hardened and nitrided steels, grey and ductile irons, and copper alloys • ISO 6336-5 Method B MQ reference stress data for listed steel and cast-iron hardnesses • Save complete inputs and the selected inverse-design candidate for later continuation • Core calculations run on device; engineering inputs are not uploaded Strength results are intended for design screening. Final release should add the applicable load spectrum, life, reliability, lubrication, flank modification, and manufacturing-tolerance evaluation. DXF files contain nominal profiles; verify the cutter-generated root, modifications, and tolerance band before CAM.
