EMF Hunter vs Microwave Leak Detector
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
EMF Hunter
Transform your phone into an electromagnetic field detector. It uses your device's internal compass to measure magnetic and electric fluctuations, displaying readings through meters, graphs, and particle effects. Ideal for educational or entertainment purposes.
- Detects magnetic field strength in three dimensions
- Easy-to-read meter with LED indicators
- Multiple graph views (line, bar, polar, pie)
- Particle mode visualizes magnetic force
- Start and pause detection functionality
- Displays force in microteslas

------------- EMF Hunter ------------- This app is intended for entertainment purposes only. This app supports devices with an internal compass. This includes iPhone 3GS and newer iPhone devices. ------------- Description ------------- User your phone as an EMF (electromagnetic field) detector. This app uses the power of your phones internal compass to detect magnetic and electric fluctuations in the environment around you. This is perfect for people looking to detect magnetic fields: teachers, students, technophiles, and even Ghost hunters! This app is not intended to be a scientific instrument, and it's readings are subject to external conditions and the accuracy of the device's internal compass. ------------- Features ------------- * Detects the strength of magnetic fields in all three dimensions * Easy to read meter lets you gauge with a simple look the strength of fields in different directions * Light up LED icons display showing field strength, the more LED icons that light up, the more force there is * Graph view shows the changing values of the field from all three dimensions * Line Graph * Bar Graph * Polar Graph * Pie Graph * Particle Mode - the more magnetic force the more particles * Ability to start and pause detection * Magnetic force is calculated in microteslas
Microwave Leak Detector
This utility app uses your device's magnetic field sensor to indicate potential electromagnetic leaks from your microwave oven. It's designed for entertainment and to alert you to possible issues with your appliance's casing.
- Detects magnetic field changes
- Uses iOS device sensor
- Indicates potential microwave leaks
- For entertainment purposes
- Works on iPhone and iPad

Use this app to detect a leak in your home Microwave. Poorly manufactured or physically damaged Microwave Ovens may allow electromagnetic energy (used to cook your food) to escape into the surrounding environments. This app serves to indicate if this may be happening to you. This app utilizes the embedded magnetic field sensor in your iOS device to detect surrounding magnetic field changes. This app does not intend to serve as a fully calibrated Microwave Leak Detector, only to indicate that a Microwave Leak could be present. Microwave energy that is used to cook your food induces magnetic field changes. If your Microwave Oven has a leak, the embedded sensor in your iOS device can be used to detect those magnetic field changes leaking through your Microwave's casing. This app should be used for entertainment purposes only.
