Main login page with the ability to sign-up for a profile.

After logging in, leads into the main page where you choose what allergies to scan for.

After choosing the allergies to scan for, it brings you to the scanning screen where you can either scan an item or re-choose what allergy profile you want to use.

This is the same screen as the previous, just after clicking the scan button. Scan the item's barcode to see if you're allergic to it.

After scanning, one of the possible results is a SAFE screen, where you can see the list of ingredients, change allergy profile, and scan another item if you wanted.

Another one of the possible results is a WARNING screen to let the user know that this item they just scanned contains their allergy. Again, you can see the list of ingredients, change allergy profile, and scan another item if you wanted.
