About this app

Think Dirty is the easiest way to learn about the potentially toxic ingredients in your cosmetics and personal care products. It’s an independent source that allows you to compare products as you shop. Just scan the product barcode, and Think Dirty will give you easy-to-understand info on the product, track dirty ingredients, and shop for cleaner options.

• Search by Keyword or Barcode Scanning: Our database lists over 850,000 cosmetics and personal care products from Canada and the U.S.

• Personalized Ingredient Preferences (Premium): Save time by pre-selecting your Allergens, Ingredient preferences and personalizing your shopping experience. Ingredient alerts will be presented if we find flagged ingredients in the products you viewed.

• Search by Ingredient (Premium): Unlock to get detailed information about its usage, health impact, sources, and which products contain such ingredients.

• Search by Curated Categories (Premium Feature): Unlock to access our curated speciality lists such as Mineral Sunscreens, SLES-Free Skincare, Vegan Makeup

• Expiry Date Tracker: Is that mascara still good to use, but don't remember how long you have had it? Now you can keep track of its expiry date on your Bathroom Shelf. Enter Open Date and Shelf Life, and you will never put expired products on your face again!

• Dirty Meter®: A comprehensive rating is given, along with detailed (but easy-to-understand) information on ingredients, certifications, and health impacts.

• My Bathroom Rating: Keep track of what’s already in your bathroom. Learn your current bathroom rating, and track your progress on “cleaning” it up.

• Upvote Non-Rated Products: Let your voices be heard! Upvote, and we will aggregate user responses and reach out to brands on users’ behalf to encourage them to get their products verified and rated.

• Shopping Lists: Save products and make shopping faster and easier.

• Shop Now: Buy products directly from Amazon.com, Amazon.ca, Well.ca, Sephora.com, and Amazon.co.uk.

• UPC Submission: Are we missing a product? Use your device's camera to scan its barcode and capture the list of ingredients with OCR, then submit it to us. For registered users who submit products, we thank you with a discount code to use our beauty box subscription. And will notify you once they are in our database.

The app is wonderful in determining what products are safe and which ones are not. However as of this year almost EVERY feature requires you to buy a subscription. To search beauty products or something as simple as body wash it wants you to pay for it's reviews when it was not always this way. I can't even see the reviews of things that I want to buy anymore with being pay walled. Absolutely sad that this is what the app has come to.

Thank you! We recently introduced a subscription fee after being a free app for 7 years. This step was necessary to ensure the long-term sustainability of our app. The cost is less than a cup of coffee and we believe that the information we provide is invaluable. Your support and patronage mean the world to us & allow us to remain independent.❤️

I previously gave this app 5 stars a few years ago when I first discovered it. Over the years, they have started charging for basic uses that they didn't previously charge for. With the free plan, you can only scan maybe 3 items and get the basic info. After that, they don't show you anything about the product you're trying to get information for unless you upgrade. I can understand charging for additional info beyond the basic score but it doesn't even give you a score! Stupid.

I have used this app for years and loved that it helped me easily determine whether a product is clean or not. However, the search feature doesn't work great and there seems to be a limited number of products. What's most annoying is that, after being free for years, they have now started charging for basic ratings and their subscription options are confusing. Not worth $200! Im looking for an alternate option
