I purchased purely for the metal detector function. There is no menu button, so I can't switch to that mode. My phone does not have a menu button. Needs to be in the app.
Hard to tell if it really works
Not an actual giger counter program.
it's fun prank.
This is a great gag app and it works as advertised. Just tap the on/off button (lower left) to start it and it illuminates red. Now you tilt your phone downwards to increase the fake mSv readings. The needle jumps into the red zone along with extreme pulsing sounds - just like a real one. You even get fake increases in mSv in the lower right of your screen as you tilt it. This is great fun to prank someone at a party making them think they are radioactive. Again, this is NOT a real Geiger counter but a joke app. Love it.
Its not real
I tried it on genuine radio active material at work & it failed completely, it only works when phone is tilted forward the further you tilt the more sounds it makes has no use other than joking.
Performs just as advertised. Now I can locate my daily dose of radiation whenever I need to.
Nice
Had it for years. Always good for a laugh
