EMF Detector vs Datacentrix Showcase 2024
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
EMF Detector
This app uses your device's sensors to detect and visualize magnetic and electromagnetic fields. Explore magnetic forces, identify potential sources of EMF, or use it as a simple metal detector. See real-time fluctuations plotted on a responsive display.
- Detects magnetic fields on x, y, and z axes
- Visualizes EMF activity in real-time
- Indicates computed field magnitude
- Functions as a basic metal detector
- Plots EMF activity as a sin wave

Explore magnetic fields with a beautifully crafted pocket instrument. EMF Detector uses your device's magnetometer to display magnetic field strength in microteslas (µT). An animated analog dial, luminous digital display, and rolling trace bring the measurements to life in a detailed industrial-style panel. READ THE FIELD • See total field strength or select the signed X, Y, and Z components. • Follow changes with the animated needle and recent-history trace. • Use HOLD to freeze a reading and RESET to clear session peaks and history. • Switch between 100, 500, and 2,000 µT dial ranges without changing the measured value. • View calibration status from Apple's calibrated magnetic sensor data. HEAR AND FEEL THE INSTRUMENT • An electrical hum changes pitch with the selected field's strength. • Mechanical button sounds and tactile feedback give the controls a physical feel on supported iPhones. • Mute the hum and button sounds with one control. Your choice is remembered. MADE FOR IPHONE AND IPAD • Portrait and landscape layouts. • An included field guide explains the readings, controls, and calibration. • Clearly labeled demonstration mode lets you explore the instrument without live sensor data. • No account, ads, subscriptions, or in-app purchases. Readings stay on your device. Live measurements require a device with a magnetometer. Slowly rotate and tilt the device to help iOS calibrate it. Magnetic cases, chargers, nearby metal, and calibration can affect readings. EMF Detector measures magnetic fields, not electric fields or radio-frequency radiation. It is not a calibrated safety instrument, wiring-fault detector, or paranormal detector. The hum represents field strength; it does not measure the field's physical frequency. Requires iOS or iPadOS 26 or later.

Verdict
The clearest difference is price: Datacentrix Showcase 2024 at Free against EMF Detector's $0.99. Datacentrix Showcase 2024 also leads on iOS requirement (10.0 vs 26.0). EMF Detector's advantage is device support. On in-app purchases there is nothing between them.
