METAL DETECTOR PRO - 7 Modes, 1 iPhone Turn your iPhone into a professional-grade metal detector and magnetic field analyzer. MetalDetector Pro harnesses your device's built-in magnetometer to detect metal ferrous e magnet , measure electromagnetic fields, and visualize magnetic data in stunning real time — no extra hardware, no subscriptions, no limitations. ••• 7 POWERFUL MODES - SEARCH The classic metal detection experience, reimagined for modern iPhones. The app continuously reads the ambient magnetic field in microtesla (µT) and alerts you with audio beeps and haptic pulses as intensity changes. A 20-bar VU meter and three LED indicators give you instant, at-a-glance feedback. Perfect for locating hidden nails, coins, keys, electrical wiring, pipes and any ferromagnetic object beneath walls, floors or soil. • THRESHOLD Set a custom detection threshold and let the app work hands-free. Alerts fire only when the field exceeds your chosen sensitivity level — ideal when you need to focus on the surface you're scanning without watching the screen. • EMF Electromagnetic field meter mode. Identify live electrical wiring hidden inside walls, locate appliances radiating strong fields, and monitor your environment with a dedicated EMF intensity readout. A useful companion for electricians, home inspectors and the curious. • COMPASS A precision magnetic compass driven entirely by the magnetometer sensor — no GPS required. Clean neomorphic design with a smooth, real-time compass rose. Reliable heading data anywhere, even underground or indoors. • SPHERE The most visually striking mode in the app. Every sensor reading is plotted as a colored dot on a rotating 3D globe. Watch your scan history build into a living magnetic map — green for low-intensity fields, climbing through yellow and orange to alarm red as intensity rises. A mesmerizing way to understand the invisible forces around you. • DEPTH Estimate how deep a metallic source is hidden using real-time field gradient analysis. Point your iPhone at a wall, floor or patch of ground, press CALIBRATE, and receive a live distance readout in centimeters. Great for locating buried pipes, conduits and structural reinforcement. • 3D FIELD An immersive real-time particle simulation driven by the live magnetic field vector. Hundreds of animated particles drift, swirl and accelerate in response to the X, Y and Z field components. The stronger the field, the faster and more dramatic the particle storm becomes. ••• PREMIUM FEATURES ••• • Live µT readout with individual X, Y, Z axis values on a retro LCD display • 20-bar VU meter with green, yellow and red intensity zones • 3 LED indicators with progressive glow effect • Scrolling magnitude graph — last 150 samples always visible • Precision sensitivity slider with real-time signal filtering • Audible beep alerts with adjustable sensitivity • Haptic vibration feedback, independently togglable • Flashlight/torch for dark and confined environments • Auto-lock disable — screen stays on during extended scans • Neomorphic UI in both Light and Dark theme • Authentic retro LCD display with green phosphor aesthetics • Full localization: English and Italian ••• WORKS ON EVERY IPHONE No LiDAR. No external sensors. MetalDetector Pro runs on any iPhone with iOS 15 or later, using only the standard magnetometer chip built into every device. No camera permissions. No location tracking. Your data never leaves your device. ••• WHAT CAN YOU FIND? Buried metal ferrous e magnet-Nails and screws hidden in walls-Underground pipes and conduits-Live electrical cables · Lost keys and metal objects · Metal studs behind drywall · Old relics and artifacts Whether you're a DIY enthusiast, a treasure hunter, an electrician or simply curious about the invisible magnetic world around you — MetalDetector Pro delivers the most powerful, beautiful and complete magnetometer toolkit on the App Store. Download now and start exploring the world beneath the surface.

byeWatch — Eight instruments in a pocket watch A pocket watch that is more than a clock. byeWatch brings eight different instruments into a single pocket-watch-inspired interface. Instead of searching for buttons, interact with the watch like a real mechanical instrument. Turn the crown to move between instruments, and use the switches around the dial to control each one. ■ 8 INSTRUMENTS • Astronomical Track the Moon phase and tilt while the Sun and Moon move across the sky according to their actual altitude and hour angle for your location and date. • Chronograph A classic chronograph with 60-second, 30-minute and 12-hour subdials. Watch the mechanical movement through the window, with a moving weight that reacts when you shake the device. • World Clock Rotate the city drum to select a city and see its local time, date, weekday, UTC offset and time zone. • Stopwatch Measure time down to 1/10 second and record lap and split times. • Sunrise & Sunset See today's sunrise and sunset times and visualize the part of Earth currently illuminated by the Sun. Digital views include a 24-hour solar-altitude graph and an approximate tide curve. • Compass Points to true north rather than magnetic north. WMM 2025 coefficients are built into the app so magnetic declination can be calculated offline using your location and date. • Barometer & Altimeter Read atmospheric pressure in hPa and mmHg and monitor whether pressure is rising or falling. Devices with a barometric sensor can also display barometric altitude. • Metal Detector Uses the device's magnetometer to detect local magnetic anomalies and displays them as a relative proximity index. ■ INTERACT LIKE A WATCH Turn the crown left or right to switch instruments. Pull the crown downward to open settings. Use the 11 and 1 o'clock switches for instrument-specific controls. Use the 3 o'clock switch to reset. Swipe the dial left or right to enter digital mode. Swipe upward below the watch to reveal the information panel. Rotate the device horizontally to open the landscape information panel. ■ MAKE IT YOUR WATCH Customize the case color, dial color, hand design and index style. Choose from silver, platinum, graphite, steel, gold, champagne, brass, rose gold, copper, navy, blue steel and teal. Reorder the instruments or hide the ones you do not use. ■ ANALOG AND DIGITAL Each instrument has its own visual language. When an analog dial is not enough, switch to digital mode for detailed graphs, tables and readings. View solar-altitude graphs, pressure history, stopwatch lap records and a magnetic-anomaly scope. In landscape mode, additional information such as battery, pressure, temperature, solar path, sunrise and sunset, Moon phase and coordinates can be displayed together. ■ DESIGNED WITH OFFLINE USE IN MIND Location data is used on the device and is not transmitted outside it. WMM 2025 coefficients are built into the app, allowing magnetic declination to be calculated without an internet connection. ■ SENSOR REQUIREMENTS Compass and metal detector require a magnetometer. Barometer and altimeter require a barometric sensor. Sunrise/sunset and magnetic declination use optional location permission. If a required sensor is unavailable, the instrument can still be opened and the app displays an appropriate notice. ■ IMPORTANT NOTICE The metal detector is not a radar or professional metal-detection device. Its readings represent a relative magnetic proximity index, not a distance in meters. It must not be used for buried-object detection, safety inspections or professional detection work. byeWatch is a hobby instrument and is not intended for safety-critical navigation, aviation, surveying or other professional applications. Requires iOS 16.0 or later. Languages: 한국어 · English · 日本語 · 简体中文 · 繁體中文 · Deutsch · Français · Español · Italiano · Русский

Verdict
The clearest difference is update cadence: byeWatch at every 6 days against Metal Detector & Magnetometer's every 5 months. byeWatch also leads on iOS requirement (16.0 vs 18.6). Metal Detector & Magnetometer's advantage is price ($1.99 vs $2.99). On ads, in-app purchases and device support there is nothing between them.
