Weight Scanner is a novelty prank thumb print scanner app that tries to determine your weight based on a mock fingerprint scan. Simply place your thumb on the scanner and the app will tell you how much it thinks you weigh! Great gag for parties or for impressing the ladies at the club!

You can adjust the speed of the scan simulation, and you can set your own custom response, so that you can play the ultimate prank on your friends and family! There are also various themes to choose from, so you can adjust the look of the app to match your personality! You can even have the app speak your scan results to you over your device speakers.

I weigh 86 pounds on regular scale when did this app it came out that I was 199 pounds.
This is another example. When I used a regular scale I was 87 Ibs but when I used this app it said I was 139, which is extremely off and it was changing every time I tried using it again....

Just a prank bro

For everyone who is mad this game is just made for entertainment purposes only. Stop hating and actually look at the description. But anyway this is hilarious and it actually worked on my friend until she tried it again and then I revealed to her that it was just a prank. Just saying, anyone that is hating, just zip it up because this world has too much hate in it already, Thank you for developing this game, developers.

100% trash

this is horrible. every time I scan my thumb it gives me different weights that are for sure not accurate. 160, 149, 156, 187...
I’m actually 125. I do not recommend this app at all it’s trash. If I can give this a 0 star rating I would.
