### 5/5 — Great app

*2026-04-28*

If you are looking for an app to give you some idea of the EMF that we are exposed to each and every day the you can’t go past this one, even if it’s a bit shocking

### 5/5 — Terrific App

*2026-03-30, version 6.2*

Accurate, helpful and one of the main apps I use in all paranormal investigations. Really well put-together and beautiful to look at. Honest review. Thanks.

### 4/5 — Seems to work

*2026-03-10, version 6.2*

I’m going to have to use it more but it seems to be working and I’m going to add a EMF pump to add more electricity to the room. Thank you it’s been fine and I’m going to use it more often now,

### 5/5 — Seems to work as promised

*2026-02-18, version 6.2*

It’s a fun app!

### 5/5 — Useful APP

*2026-02-11*

l love this app and recommend it to all who are curious or sensitive to electromagnetic radiation leakage or RF background radiation that our electronic devices create.  Often, people do not realize the impact or even the significant amount of emf that often surrounds us in urban areas.  If you’ve been sick chronically without much ability to heal or understand why, then perhaps you ought to try this app to begin investigating your current living space to see if you’re potentially experiencing the negative health effects by living in the constant sea of EMF/RF Emissions. Once identifying the problem, only then can you begin to understand it and how to thwart it from continuing to cause chronic and acute illnesses in you and your family’s lives.  This app is very simple yet effective and visually looks great and is easy to read from a distance when taking measurements. See for yourself and don’t take someone else’s word for your health and safety, use this app and find out yourself right now the threat you may be unaware lurking in your home.

### 5/5 — Ок
