User reviews

I was skeptical but it’s pretty great

It’s much better than the other 3 highly rated ones I’ve tried so it’s likely as good it gets for a phone app.

The problem with each EMF app is hypersensitivity towards totally wrong things and so far the only clear weakness this one has is springs. As in mattress springs, chair springs, etc. Pretty weird but if it’s the only weakness then it still beats the competition.

I’m just glad my mattress isn’t haunted, just has a ton of springs hehe.

I was gonna spend a lot on some sus device from Amazon but this looks good enough to save me some moolah.

Just hit the stop button every min or two cause the EMF value likes to creep up and stay with the bigger numbers.

Oh and I like the lowest sensitivity setting but all of them work great.

Fun app overall, enjoy!

Response from developer

Thank you for the detailed review! We're glad to hear the app performed better than the other EMF apps you've tried and helped you avoid buying additional hardware. The readings are based on your phone's built-in sensors, so certain metal objects like mattress or chair springs can sometimes influence the results. We appreciate your feedback about sensitivity settings and value drift, and we'll continue working on improving accuracy and the overall experience. Thanks for using the app!

EMFMeter is just phenomenal

I use this app to detect magnetic fields and it works just as effectively as commercials alternatives. Impressive tool

Rubbish app, shows wrong data.

Good 👍

I’m a little confused about IAP. Is the $0 a lifetime promotion ?

FAQ

What can EMF Detector measure?

EMF Detector measures magnetic fields using your iPhone's built-in magnetometer. It displays readings in microtesla, milligauss, or Gauss, similar to handheld meters. It does not measure Wi-Fi, 5G, or ionizing radiation.

How does EMF Detector help with ghost hunting?

EMF Detector features a ghost hunt mode that uses audio and haptics to alert you to magnetic spikes. Investigators use these spikes as a starting point for detecting potential paranormal activity, though it is not a direct spirit detector.

Can EMF Detector find studs or wiring?

Yes, EMF Detector can function as a metal and stud finder. By sweeping a wall, it can detect changes in magnetic fields that indicate the presence of studs, pipes, or wiring.

What are the benefits of the Pro version?

The Pro version of EMF Detector removes advertisements and unlocks advanced features. These include directionality, full history access, high-EMF alerts, and PDF export capabilities for your session logs.

Does EMF Detector have ads?
