## What is Gauss Meter?

This app is primarily used to measure magnetic field strength all around. It could also be used as a metal detector. This app contains the following features:

1) The magnetic field measured by this app is the total magnetic field in the device's vicinity without device bias (Earth's magnetic field plus surrounding fields, without device bias).

2) Plot the measured data in real time.

3) Multiple units supported: nT, µT, mT, mG and G.

4) Measurement duration and measurement frequency are customizable.

5) Users could set alert value to some level (Ex. 120 µT). When the measured magnetic field exceeds the alert value, it will alert users.

6) The location information of the measurement points could also be obtained, and all the measurement points could be shown in map.

7) All measured data could be exported as a csv format file for post process.

8) In addition, users could also add photos, videos and voice records to the measured data, and the photos, videos and voice records could be downloaded through iTunes.

## Key features

- Magnetic field measurement
- Real-time data plotting
- Multiple unit support
- Customizable alerts
- Map measurement points
- Data export to CSV
- Attach photos, videos, voice records

### 5/5 — Love The App

*2022-08-04*

Thanks for this nice app. It would be great if I could do a screen snap! What is the max Gauss the app can measure on the iPhone?

**Developer response:** Thank you for your appreciation of this app. To make screen snap, you could use iOS built in funtion. Please see the instructions in the followed link: https://support.apple.com/guide/iphone/take-a-screenshot-or-screen-recording-iphc872c0115/ios. The Gauss value is read from the built-in magnetometer in iOS device, and the max value differs on device pattern. However in order to avoid damage from your device, it's not recommended to use this app in high Guass environment.

### 5/5 — Thank you for this App 👍🏻

This app works great, specifying detailed oriented information that’s very important for researchers.  EMF’s ARE DANGEROUS when used to target individuals in closed door settings like apartments. This device has truly came in handy and has worked in my and my family’s favor. It’s gave me information that I needed and also a platform to save and record the data with a precise location of the event. We’ve been enduring the pain for a little over a year now and it was a scary time in our life’s. Our pets has suffered we have and the reason being, simply the people behind it have bad intentions to harm and they will definitely deceive you. Once they somehow realized I was documenting these wicked ways try shut down the EMFs and I know that because I can’t pick up the data anymore.. So thank you for creating this kind of perfect App! God bless you!

Excellent application. With additional few features in option many, mobile phone could be turned into geophysical measurement device.

### 1/5 — Does not work

*2019-12-23*

I am going to be requesting to have my money refunded. I work with electrical engineers and we have actual Gaus meters. We compared the readings with the app and they are not accurate at all. In fact the readings don’t change at all. They read constantly at about 35-45 never changing no matter what. We tested it on large distribution lines and which should have sent the numbers soaring but they didn’t change. :( bummer

### 1/5 — Gauß Meter

Unzureichende Beschreibung der Bedienung.

### 5/5 — Eye opener!

*2019-01-30*

I measured my awake Ipad air 2 at 157 micro T, my awake Galaxy Tab A was 1833 micro T and the awake HP laptop was 337 micro-Tesla. This shows that there dangerous levels of microwave radiation with wifi devices!

### 5/5 — Gauss Meter

*2017-03-13*

Très simple et export Excel permettant une analyse détaillée

### 5/5 — Beste emf app

*2016-11-09*

Sehr ausgereifte app für emf analysen mit der tollen möglichkeit die messungen mit orts und zeitangaben sowie fotos und filmen zu dokumentieren

### 1/5 — このソフトおかしい

*2016-10-01*

高圧線の下の磁界強度を測りたくて購入したが、このソフトの指示値はいくらなんでも大きすぎる。ソフトの説明の画像を見ても1000μT以上の値になっている。普通の街中でそんなに大きな値になるはずがない。

### 1/5 — Doesn't work on iPad pro
