I will be using this app to teach a science lesson. I will give students magnets of different strength and a ruler and leave it to them to create and answer their questions. The app itself works reliably on my iPad and iPhone. Any issues may be due to the device used and not the app.

I use the app to locate the wifi antennas on my devices (cell phones, iPad, computer etc). Then I can avoid putting that area near my body. I find it by scanning with my phone around a device and when the needle goes to red that’s the antenna giving out and picking up it’s dangerous level of wifi. I especially want children to see how certain areas of a device are important to keep at a distance. I also use interventions to reduce the level of dangerous emf such as pendants with coiled copy(counterclockwise) and high-quality obsidian, in addition to crystal in a resin. Yes they truly work if you have one correctly made. I have tested it by putting the pendant next to the antenna and the needle drops to low yellow or green. I also check for cell towers nearby.

I needed a quick tool to locate a 8" diameter round steel vault cover under 2" of packed gravel and dirt. The app did the job once I figured out how close (very) to hold my phone to the ground. I looked like an idiot on my hands and knees on the side of the road, but I found the vault and got the job done.

This tool is simple to use for gaining an appreciation for the low level harmful unseen waves in confined spaces. I haven’t yet used this tool outside my living space. It is very exciting when sharing what such a feedback meter can reveal. Good job!
