Concerned about magnetic fields in your home? Detect and measure them with this easy to read app scientifically designed for your device! This is an easy to use app to detect and measure 50Hz/60Hz alternating magnetic fields that could be present in your home generated by things like microwaves, hairdryers, electric space heaters, video game consoles, AC/DC power adapters and overhead power lines. WHAT MAKES THIS APP DIFFERENT? Static or constant magnetic fields like the Earth's magnetic field are less of a health concern than alternating magnetic fields. This app was designed to detect and measure alternating magnetic fields most commonly found in living spaces. These magnetic fields can be generated by electrical devices running on your home mains AC electricity. These alternating magnetic fields have a frequency of 50 or 60 Hz depending on your country. Studies of the health impacts of alternating magnetic fields as publicized by the International Agency for Research on Cancer (IARC), the World Health Organization (WHO), and by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) has raised the awareness of alternating magnetic fields and generated interest in measurements of them in public and living spaces. The alternating magnetic fields you may encounter in your home can vary tremendously in strength depending on the device and your distance from it. This app measures the 50 or 60 Hz component of any alternating magnetic field with your device if equipped with a magnetometer. The detection and measurement of alternating magnetic fields is achieved by analyzing functuations in the magnetic field measured by the magnetometer in your device. Normally the magnetometer is used for measuring constant magnetic fields, for example in a compass application. In the presence of a sufficiently strong 50/60 Hz alternating magnetic field the magnetometer measurements fluctuates with time. These fluctuations can be detected and measured by a Fast Fourier Transform analysis. This proven scientific method is able to achieve a sensitivity down to about 0.1 micro-Tesla, much smaller than the Earth's magnetic field of about 40-60 micro-Tesla! The calibration of several different devices running this app was cross checked with a separate sensor that was tested using NIST traceable methods and instruments. The accuracy of these devices was found to be as good as 20%, however because the location of the magnetometer in each device is not known precisely the measurement you obtain may have a larger uncertainty like 50%. The main use for this app is to detect and measure 50/60 Hz alternating magnetic fields in public and living spaces. However this app is not a substitute for a professional magnetic field measuring device, and is for private or entertainment purposes only. This app does not work on an iPod or any device that does not have a magnetometer that is normally used for a compass application. The Watch App works on a Series 5+ and SE. Magnetometers in different devices operating under different conditions can produce poor quality input to this app, affecting the measurement accuracy.

AMagScope is used to detect and measure 50Hz/60Hz alternating magnetic fields that can be generated by common household electronics like microwaves and power adapters. It analyzes fluctuations in your device's magnetometer readings to identify these fields. ### How accurate is AMagScope? While cross-checked calibration showed accuracy as good as 20%, the exact location of the magnetometer in each device is not precisely known, which can lead to uncertainties of up to 50%. It is intended for private or entertainment purposes and is not a substitute for professional equipment. ### Does AMagScope work on all devices? AMagScope requires a device equipped with a magnetometer, which is normally used for compass applications. It does not work on iPods or devices lacking this sensor. The Watch App is compatible with Series 5+ models. ### What is the price of AMagScope? AMagScope is available for a one-time purchase of $1.99. ### When was AMagScope last updated? The latest version of AMagScope, 1.6, was last updated on September 4, 2022. ### What is the age rating for AMagScope? AMagScope has an age rating of 4+, making it suitable for a wide range of users. ### Does AMagScope have ads? No, AMagScope is ad-free, providing an uninterrupted user experience. ### What is the sensitivity of AMagScope? This application can achieve a sensitivity down to about 0.1 micro-Tesla, which is significantly smaller than the Earth's magnetic field. ## Version history (last 4 releases) ### 1.6 — 2022-09-04 Improved 50 Hz operation accuracy. ### 1.5 — 2021-06-05 Now also runs on an Apple Watch! The Apple Watch app runs independently of the iOS app and is powered by the same magnetometer in the Series 5+ and SE used for the compass. We also fixed a technical issue affecting results for 50Hz detection. However the measurement update frequency for 50Hz is longer (7.5sec) than for 60Hz operation (2.5sec). ### 1.4 — 2021-05-19 Thanks for your feedback! We have made improvements to the main screen and the organization and presentation of the technical details. ### 1.3 — 2021-04-20 No release notes. ## Apps similar to AMagScope | App | Rating | Price | Category | | --- | --- | --- | --- | | [EMF Detector - Radiation Meter](https://appshunter.io/ios/app/emf-detector-radiation-meter/id1435484022) | — | Free | Utilities | | [GammaPix](https://appshunter.io/ios/app/gammapix/id578395611) | 2.0 (4) | $14.99 | Utilities | | [CDAPDTip](https://appshunter.io/ios/app/cdapdtip/id1565191688) | — | Free | Utilities | | [Contacts To PDF File Converter](https://appshunter.io/ios/app/contacts-to-pdf-file-converter/id1446169814) | 4.6 (12) | Free | Utilities | | [Electromagnetic EMF Detector](https://appshunter.io/ios/app/electromagnetic-emf-detector/id1031336728) | 4.4 (211) | $1.99 | Utilities | | [IoT Log](https://appshunter.io/ios/app/iot-log/id1448803270) | — | Free | Utilities | --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
