Think Dirty is a great app that i use for seeing if a product is safe for me. I also like how you can see the effects of bad ingredients and other peoples opinion on the product. Something that can be improved is the barcode scanner since it doesnt always read it right and find the product. Overall its a good and helpful app!

I love the idea of this app. I love how you can basically scan any product and see the ingredients and if they are bad and why etc. BUT what I don't like is labeling a product as "all bad" or red just because of a single not so good ingredient. It's usually just fragrance in a lot of cases it's not that big of a deal. Just because a product has a single bad ingredient doesn't necessarily mean the product is bad in my opinion. But overall really informative app and a great tool.

I like the app, but I'm disappointed that many products are not in the database. It definitely takes a while to add the information about a new product. We should also be able to add products without using the barcode. Most of my current products have the barcode on the box and not the product itself, and of course I threw out the package when I bought them (before I found out about the app). A lot of the products aren't manually vetted so I don't know how reliable most of the ratings are

Thank you for writing to us! Have you tried using our manual search option within the app? Chances are we do have the product, but it is under a different barcode when scanned. If you still can't find the product, you can submit it through the app or at 🥰
