Hello

I wonder if iPhone can be used as tool, e.g. for EMF measurements. Rarely can one rely on those app decriptions. I am unsure what kind of sensors it has and what it really measures. Does anyone have experience with that, i.e. what can it be used for in this context, how does it compare to dedicated devices?

So far the only apps I like are the compass, mapping apps, GPS and also google earth. its nice to look over an investigation site lay of the land.

As far as the EMF meter , the ghost radar, the app that generates words they are for entertainment only. Of course with everything some people think they work but they are the ones that think the banging water pipe is a ghost.

Agree with use of geographic info. How about these apps measuring magnetic field, some do so as a vector. range up to 0.999 micro Tesla.

I tested 2 such apps and only get what I think must be earth magnetic field at about 47 micro Tesla. Sometimes the values go above range, which must be rather strange, 0.9 is very high. so I assume these apps are not really useful and do not copmpare to a dedicted EMF meter? problems with frequency of field? just wondering, have never used EMF meter, would be nice if iphone could do that, any additional device to carry and take care of batteries is bad...
