App Description

Finally, mobile technology can provide an answer to the age old question - "does this outfit make my butt look big?"!

Husbands and boyfriends, you no longer need to squirm when your woman asks you that question. All you need to do is pull out your mobile device and let it do the rest!

Using our top secret "butt detection" technology (it's like face detection but for backsides :) we can now help you answer that question with complete accuracy.

Here's how it works:

Take a picture of the butt you want to analyze while wearing the outfit in question. Click the "Buttilize!" button, and that's all. The application will analyze how it looks and provide you with the answer.

if you feel that the photo doesn't do the butt justice, you may also shrink the butt, and then run the same analysis for better results.

When done, you can share the results with your friends and family on social media.

If you're feeling frisky, you can also enable negative feedback to get more interesting comments from the app.

Disclaimer: This app is for entertainment and joke purposes only and should not be use to provide an accurate assessment of one's behind.
There is no such thing as butt detection software, and even if there is, it's not in this app.
