As a critical thinker I was skeptical and expected this to be a novelty app “for entertainment purposes only“. I was surprised at how well it worked & tested it with a variety of objects at different sensitivity levels. I have yet to locate my lost earring behind a piece of furniture but it was super sensitive with a knife, a razor blade, phone charger, accessory hardware. It did not respond at all to any jewelry I was wearing. That makes me think it won’t detect my lost earring or maybe it just doesn’t respond to sterling silver.I think the ppl who claimed it found a diamond ring are full of it… Unless it was junk jewelry but it does work well for numerous items and I give kudos to the developer for offering it freely… Without even having to watch ads. 👏🏽

I have an extremely rare coin I took it out to look at..thinking of selling. Well I miss placed it could not remember where I set it down. Was really freaking out in complete mental breakdown call the paramedics mode. Had a thought about these apps I heard of. This seemed to have the highest rated & came out on top in the search. I went with it.. Turned on and oh my good Lord it lead me to it in 70 seconds I had set it down on the bed and this detector had me down looking under the bed the best guide EVER. I would HAVE NEVER KNOWN! As I have bed skirt DARK BROWN that covers the sides of bed and the display box the coin is in is jet BLACK. This is unbelievable to me, I'm still in shock at the extreme accuracy of the app. I found this app on a whim ok! Want to say how grateful I Am to the developers they worked hard obviously and had the knowledge of how to create very good metal detector very useful in times of emergencies! "GUARANTEED" as "my" word to work for you as needed.

It’s not perfect, but given the poor reviews I saw on some other apps that report to do the same thing, I was reasonably impressed! It has a sensitive spot that is likely right where the magnetometer is in your phone. Take a bolt and stand it upright with the head up and then sweep your phone up and down and back and forth until you find where the highest signal response is, and note the position of the bolt head. That will be the location of the mail or screw when you find it in the wall. Have not tested it yet, but this probably only works on ferrous metals. But for the price I can’t say I’m at all disappointed. Just moderate your expectations though, as this is still not going to give you X-ray vision. I think it only detects ferrous metal like nails and screws, and probably won’t detect wires unless they are steel wrapped.

Yesterday I started using a brand new set of throwing knives I got with my dad, but after just a few throws, I lost one and couldn’t find it despite a good 20-30 minutes of looking. This morning I got up and went outside to look some more. But when my dad came outside, he showed me the app, and I thought, “that’s definitely fake.” But after we tried it out on some metal, I got it, despite still having some doubts, and I got to work. About five minutes later, we found it. My conclusion, one, use it on the sensitivity two above the minimum, otherwise, it’s either too weak, or way too powerful, and is ringing nonstop. Two, don’t use this app if you’re trying to be a treasure hunter or something, it’s definitely not powerful enough for that, but if you lost something metal, THIS APP IS GREAT.
