Been using Ultimate EMF Detector Real Pro for a couple months now. It’s basically an app that lets you measure electromagnetic fields around you. Pretty solid if you’re into that kind of thing.
Here’s what you can do – there’s an advanced mode with graphs, sound and vibration alerts. And there’s also a simple mode and a classic analog meter mode. It’s got XYZ readings, max-min tracking, and you can even record the data to a text file. Really useful if you’re trying to track down sources of EMF.
Look, if you’re concerned about EMF radiation, you’ll probably like this. It’s not perfect – the ads can be a bit annoying if you don’t pay. But overall it does a solid job and is worth checking out.
