EMF Radiation Detector

So i have a EMF reader that i just got today, And i was comparing the app to the real EMF reader it does red on the real emf reader when my laptop is near it and orange going to red on the app if u cant afford an EMF reader then get this app i gave it a 3 out of 5 cause its not totally accurate but it works for a Substitute but otherwise you should get the real thing. -Vega

This app seems to effectively detect electromagnetic radiation in the range of radio waves and magnetism. When I bring a magnet close to my phone, the detector goes nuts into the high range. Also responds strongly to my automotive “keyless” key, which presumably emits radiation in the RF range. Responds moderately when placed next to my digital video recorder, which sends RF signals to my wireless earphones. No response over baseline when place next to my wi-fi router. And no response at all when placed next to a hunk of uranium ore. The developer needs to clarify exactly what EMF frequency ranges this detects. Seems to be more of a magnetism detector, which makes sense, since the units are micro-Teslas, a unit used to measure magnetic fields. This app, however, is definitely worth downloading and experimenting with.

This is a toy that works well for anything with a magnet in it, which is why I give it an average star. However, everything written in the description is misleading. I won't spend time discussing how so. But test it anywhere that has a magnet, it will spike. The stronger the magnet the more it'd spike. It's only detecting "magnetic fields" not "EMF" using the accelerometer or maybe gyroscope within the iPhone device. There's a diff between the two.
