Electromagnetic EMF Detector vs Vibration Meter, seismograph
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Electromagnetic EMF Detector
This app simulates detecting electromagnetic fields and electrosmog using your device's compass. It identifies ferromagnetic metals and can alert you to potential sources of radio-frequency EMF from common household appliances. While intended for entertainment, it records measurements with timestamps and offers a guide to radio-frequency guidelines.
- Simulates EMF and electrosmog detection
- Detects ferromagnetic metals
- Warning beep near emissions
- Records measurements with timestamps
- Table guide for radio-frequency guidelines
- Detects magnetic force on three axes

This app is intended for entertainment purposes only and does not provide true electromagnetic and electrosmog detector functionality. Track magnetic fields near you. A warning beep will be activated to warn you. The app detects ferromagnetic metals using the iPhone's built-in compass feature. Also works as Electrosmog (EMP) detector. Detect many kinds of home appliances that create radio-frequency EMF. For example:plugs,cell phones,routers, baby monitors, doorbells, intercom systems,night alarm clocks, electronic appliances , electrical wire, antennas. You can check the limit allowed in the "Radio-Frequency Guidelines - for continuous and prolonged exposure" in the instructions button of this app. The higher measures of magnetic fields are stored. Even the time when the measure was taken, so you can locate the source of magnetic emission. Note: This app will not work on an iPod Touch, since it does not have a compass hardware. +++ FEATURES: -Track high magnetic fields and when has it been measured. -Table guide "Radio-Frequency Guidelines - for continuous and prolonged exposure". -Warning beep near focus emissions. -Detect the strength of Magnetic force fields on all three axis’s (x,y,z). -Magnetic force is calculated in microteslas ( µ T ) -Record your readings with a time & date stamp of each event. -Store until 100 records. -Send measures by email. If you have any issues to report or suggestions to make, please email the device you’re using, iOS version, and a detailed description of the problem to bellostudios@gmail.com
Vibration Meter, seismograph
This application uses your phone's accelerometer to measure and record vibrations from various sources, including earthquakes and everyday objects. It displays ground motion on a graph and uses an instrumental intensity scale for analysis. You can also monitor and share your measurement results.
- Measures vibration strength
- Detects seismic waves
- Uses accelerometer for analysis
- Displays ground motion graph
- Utilizes instrumental intensity scale
- Monitors and shares results

Vibration meter is an app called seismograph or seismometer, which measures the strength of vibration, quakes, earthquakes, vibrations of the human body or any other objects around you. Our app allows for detecting and recording of seismic waves generated by earthquakes, volcanic eruptions, avalanches and other sources of vibration and shocks. Accelerometer in your mobile phone is used for detection of vibrations and measurement analysis. Graph presents a record of the ground motion at a measuring point. Ground movement or an object is presented as a function of time in the three Cartesian axes, with the z axis perpendicular to the Earth's surface and the x- and y- axes parallel to the surface. Mercalli intensity scale is a seismic scale used for measuring the intensity of an earthquake. It measures the effects of an earthquake and it is distinct from the moment of magnitude. Richter Scale assigns a magnitude number to quantify the energy released by an earthquake. Peak Ground Acceleration (PGA) is equal to the maximum ground acceleration that occurred during earthquake shaking at location. PGA is equal to the amplitude of the largest absolute acceleration recorded on an accelerogram at a site during a particular earthquake. In this app we use Instrumental Intensity Scale (developed by The United States Geological Survey) which maps peak ground acceleration and peak ground velocity on an intensity scale similar to the felt Mercalli Scale. These values are used to create shake maps by seismologists on around the world. Mercalli Intensity Scale distinguishes the following levels of vibration and impact damage: I. Instrumental - Not felt. Recorded by seismographs. II. Weak - Felt only on top floors of high buildings. III. Slight - Felt indoors, like a passing light truck. IV. Moderate - Windows, doors rattle. Like passing train. V. Rather Strong - Felt by all. Small objects upset. VI. Strong - Books off shelves. Trees shake. Damage. VII. Very Strong - Difficult to stand. Buildings damaged. VIII. Destructive - Significant damage. Trees broken. IX. Violent - General panic. Serious damage. Cracks. X. Intense - Most buildings destroyed. Rails bent. XI. Extreme - Rails bent greatly. Pipelines destroyed. XII. Catastrophic - Near total damage. This app allows you monitor and share the results of your measurements with other users. Measure and monitor all vibration and shocks using smartphone or tablet!

Verdict
The clearest difference is price: Vibration Meter, seismograph at Free against Electromagnetic EMF Detector's $1.99. Vibration Meter, seismograph also leads on rating (4.7 vs 4.4) and ratings volume (727 vs 212). Electromagnetic EMF Detector's advantage is review sentiment (79% vs 42%) and update cadence (every 5 weeks vs every 7 months). On ads, in-app purchases, monetization model and device support there is nothing between them.

Vibration Meter, seismograph is free to download; Electromagnetic EMF Detector costs $1.99 up front. Electromagnetic EMF Detector sells 2 one-off in-app purchases and Vibration Meter, seismograph sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Vibration Meter, seismograph holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 212 and 727 respectively. Written reviews complicate that: 79% of Electromagnetic EMF Detector's written reviews are positive against 42% of Vibration Meter, seismograph's, so the app with the better star average is not the one people write more warmly about.
Electromagnetic EMF Detector ships an update every 5 weeks, Vibration Meter, seismograph every 7 months. The most recent releases landed on October 22, 2026 and October 24, 2026 respectively.
