Will revisit review after further evaluation. ### 4/5 — Nice *2025-10-03, version 6.9* Simple and easy to use! ### 5/5 — EMF detector *2025-09-28, version 6.9* I’m still learning how to use this tool but so far it seems very sensitive. It’s easy to use and I like that it saves my readings. ### 5/5 — Great tester for safety *2025-09-19, version 6.9* I have a pacemaker and has a physician. I’ve decided to be cautious about EMFs. This Tester has helped me and is proving to be very interesting. ### 5/5 — Great app *2025-09-09, version 6.9* Excited to see it actually works!! ### 5/5 — Good app *2025-09-09, version 6.9* App is good ### 5/5 — Fresh Air *2025-09-02, version 6.9* I have tried most of these apps, always had issues with false positives, inconsistent readings at known set points, ads at the exact ‘right’ time. Delete the rest and get this one like I eventually learned to. It just works, that’s all I ask, all I need, all I want. Well done,Thanks Y’all!! ### 5/5 — works great *2025-08-31, version 6.9* good to know what’s around me that i can not see, app is stable and very accurate ## Most critical reviews (10 lowest-rated) ### 1/5 — A joke *2026-05-11, version 7.1* Values don’t change as you drive from downtown into the deep national forest with no signal around, meaning those values are random and not real ### 1/5 — Not good *2026-04-13, version 6.9* Unable to locate any type of devices with this app. ### 1/5 — Not good *2026-02-24, version 6.9* Such a waste of money. Not helpful ### 1/5 — Waste of money *2025-09-20, version 6.9* The app does not show you where the EMF is coming from. The support video doesn’t play. Just shows a blank screen. Total waste of money. ### 1/5 — Overcharged for app *2025-04-04, version 6.9* I have been charged over $70 AUD for this app and cannot contact support ! ### 1/5 — Stopped Working after Update *2025-02-15, version 6.9* After updating this app, it stopped working. Please fix. ### 1/5 — Doesn’t work *2024-10-27, version 6.9* Buggy as. Just jumps around and doesn’t give an accurate reading ### 1/5 — No funciona *2024-08-27* No sirve de nada, un timo. ### 1/5 — Completely absurd *2024-07-09, version 6.9* This is absurd, it uses the camera tech in the phone to gauge amounts of light coming into the lens. Cover the camera lens you will see. That’s not EMFs - waste of time. ### 1/5 — Doesn’t work as intended *2023-12-06, version 6.8* Unfortunately the app doesn’t really work to what I intended. Deleted it straight away. Waste of money for me. ## Most praised reviews (10 highest-rated) ### 5/5 — Very interesting app *2026-07-14, version 7.4* I am intrigued to continue using the app. ### 5/5 — Pretty Handy *2026-03-13, version 6.9* App is cool. Still working it out but it pretty good so gar. ### 5/5 — Easy, straight to the point, and accurate *2026-03-08, version 6.9* This app has validated my concern for possible high emf levels, which is very concerning because it’s right where I sleep. I installed the app, set it down and right away, the alarm on the app started going off. ### 5/5 — Handy tool for everyday monitoring *2026-03-06, version 6.9* I like to use this app when I am around other electronics to see how strong the RF radiation is and how it may affect my job ### 5/5 — Very Informative *2026-02-17, version 6.9* So far, the app has performed quite well. I’m looking forward to all that this app has to offer. It’s responsive and informative without being confusing. It sparks my desire to learn more! ### 5/5 — Audio EMF *2025-12-16, version 6.9* I build esoteric audio vacuum tube amps and EMF is very important in the placement of transformers and chokes. I’ve also used this App in discovering a problem with placement of our ONT for the optic fiber WI-FI that Frontier couldn’t solve. Great App!! ### 5/5 — Wow! *2025-12-13, version 6.9* Save some money and check this thing out. It definitely measures emf fields ### 5/5 — Perfect *2025-12-04, version 6.9* Love this works great, simple and useful ### 5/5 — Best ever *2025-11-25, version 6.9* A+ ### 5/5 — Tested and Works *2025-10-30, version 6.9* Most accurate when you use the bottom of your phone is the EMF thermometer for lack of a better word. My old iPhone 12 Pro Max is pumping out some seriously high EMF readings --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
