This app doesn’t work/1 star – Bacteria Scanner Fingerprint Review

Me and my friend downloaded this and thought it would work. Turns out that it doesn’t,because first we I know it sounds weird but we picked our ears and it said it was clean,then we washed our hands and it said it was dirty. I know it sounds weird but we wanted to know if it worked.
