I'm not crazy about the interface but, hey, it works! ### 5/5 — Happy *2021-05-06* I’m impressed with the sensitivity of this app and how well it works , I’m a real person not a generated review if it sucked I would say so but it’s good and worth downloading I use the free version 👍🇺🇸 ### 5/5 — No hassles *2020-11-09* Works just fine Thanx, ### 5/5 — Great tool *2020-09-26, version 2.4* Absolutely amazing app, I use it for work and it always finds any electronics hidden or nearby And it’s handy for finding spirits too , don’t underestimate this handy app it’s easy to use and simple to understand 5 STARS ⭐️⭐️⭐️⭐️⭐️ FROM ME ### 5/5 — Shockingly Valid *2020-08-23* After reviewing many EMF Detectors; some useless and others marginal, it turns out that this one not only senses the ‘Magnetic’ aspects of EMF, but the ‘Electrical’ as well. I found that the left side of the Max10 iPhone (mine) is the pickup side of the phone’s EMF capability. So...placing the iPhone next to a magnetic source (Speakers, Computers, Magnets, etc.), the APP responds accordingly. Surprisingly, I tested it against high electrical current wiring such as an Air Conditioning Unit or Coffee Maker. When turned ON and applying the APP, it registers the ‘Electrical’ Current Flow of the EMF APP. Yahoo! ### 4/5 — Too many add notifications *2020-06-25* Good app really works but it asks you to buy add blocker way to much ### 4/5 — Legit *2020-03-09* Seems legit so far. ### 5/5 — Recommend. I’m really pleased with this *2019-12-19* So, I got this app, thinking that it would be fake, but so far, I don’t think it is... before I download this app, I had downloaded tons of different apps before this, trying and trying to get a real emf app. How I usually test if these are real, is by putting it next to a light, or something that would produce a lot of electricity, (like putting it next to a light bulb that is turned on) and then the end number should spike (be a higher number) and so far, after testing this app a few times at different electric sources, it spiked at every one. Over all, I’m pretty pleased with this app. Thank you. Definitely recommend. ## Frequently asked questions about EMF Meter Free Utility for iPod, iPhone ### What does this EMF meter app do?
