EMF Hunter vs InterSpec Radiation Analysis
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

InterSpec assists in analyzing spectral nuclear radiation data, using a peak-based methodology. Common uses include identifying nuclides present, determining source activity, shielding amounts, source age, or other nuclear reactions present. InterSpec also provides a number of other tools useful for analyzing radiation data including spectral file format converting, dose rate calculations, interactive nuclide decay and reference information, gamma cross section calculations and references, and more. InterSpec can open data files from most common spectral radiation detectors (e.g., most NaI, HPGe, LaBr, CLYC, CsI, etc. based systems) and assist in their analysis.
