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.

I remember when this app used to be free, and I recall the founder once said she believed everyone should be able to easily see how good or bad the products on our beauty shelves are. now, there are various subscription levels for access to see if the products are toxic or not?!?! that is so unfair! 👎🏼👎🏼👎🏼 try Yuka instead, at least you can scan unlimited product labels to see toxicity ratings.

Thanks for sharing your thoughts. While different apps offer different models, it’s worth noting that some apps, like Yuka, also require payment for certain features & don’t allow searching without a subscription. Think Dirty still offers free core tools like barcode scanning & basic safety ratings. We hope you'll try the Think Dirty app again! 💚

I'd say 80% of the time when I scan an item it's not in the database, and honestly I don't get paid to submit new items into their database, and for a subscription price of $8 a month, it's just too expensive for what they offer.... Imho

Thanks for sharing your honest feedback. We understand how frustrating it can be when products aren’t listed, and we’re continuously expanding our database. Submissions are always optional, but they also help us. We appreciate your perspective on pricing and will take note of it. We hope you’ll consider giving the app another try. 💚

I subscribed for the highest subscription offer then when I scanned something that wasn't in their database they wanted me to upload all the info and pay extra to get immediate info on the product. Or I could wait for them to get back to me which was free. So basically I'm paying this company to help them build their database. 9 times out of 10 the product doesn’t exist that I scan and I have to supply all the info. I canceled the subscription so it doesn't renew after a year.
