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.

Top Notch EMF Gauss Meter with Pro Data


I love this more then my stand alone Gauss meter because this not only tracks your EMF it also saves your readings complete with map coordinates' second by second reading and can be exported from its nice built in list manager. The settings are easy to customize for changing measurement units by Tesla or Gauss it also alows to set sample time and ability to add notes photos audio and video to each reading! No gimmicks here or cheasu ghost hunter buttons!! Using my iPhone 4s gave me better readings then my expensive emf meter device.

Good App - Room for Improvement

App Purchaser

This seems like a good app. Readings are quick, easy to record and seem to increase and decrease inappropriate places.

The app is a bit buggy. It crashed the first three times I used it (but not since) and the photo option doesn't work well. Photos tend to disappear after saving. That said, I'm not deterred.

I would love to see an EMF converter or at least a conversion chart in the next update. If the app also provides some kind of reference sheet, (i.e., expected EMF output from a handful of device types) I will be thrilled.

This review would not be complete without mention of my appreciation for the absence of the "ghost busting" marketing angle promoted by other developers. Wisely, this app's developers chose to maintain their credibility, produce something useful, and market it constructively. Thank you!
