Think Dirty
Think Dirty is a highly-rated app for identifying toxic ingredients in beauty and personal care products, but recent updates have locked most features behind a paywall, leading to widespread user frustration and a significant decline in its perceived value.
Think Dirty helps users evaluate cosmetic and personal care products for toxic ingredients, offering a 'Dirty Meter' rating and ingredient breakdowns. While many users find it helpful for making informed purchasing decisions, recent changes have made most core functionalities, including searching and viewing detailed ratings, exclusive to paid subscribers.

What the developer says changed (the verdict above weighs this against what reviewers report):
Recent Searches are here! Tired of retyping that hard-to-spell ingredient? Us too. Your recent searches now show up instantly in the search bar, so getting back to a product or ingredient takes one tap. We also squashed a few bugs and made some behind-the-scenes improvements.

Who it's for
Think Dirty is for consumers who prioritize clean beauty and personal care products and want to easily check ingredient toxicity. It is best suited for those willing to pay for a subscription to access its core features, especially if they primarily use well-known, US-marketed products R4R5R8. It is not for users seeking a completely free app, those who primarily use lesser-known or international products, or those who expect a fully accurate and comprehensive database without user contribution R1R2R27R64.
Evidence note: The recent reviews skew heavily negative due to the implementation of paywalls, which contradicts the app's high lifetime rating. The developer's notes mention bug fixes and recent searches, but reviews still report bugs and the primary concern is the paywall, not search functionality.

- [R4] Love it: Very helpful when making product decisions
- [R5] Knowledge is powerful: I learned so much about the skin and hair products I used to use. I thought they were good for me! What a wake up call! I turn to Think Dirty before buying new products!
- [R9] Helpful: This app is very helpful in determining which products are best to use for skincare.
- [R13] The best app: I love it because it helps me find the best stuff to use my hair products and it tells me if it’s good or not 5 stars
- [R8] Easy to use and helpful!: Love having something I can pull up in the store and scan a barcode to tell me more about the product!
- [R42] Very helpful: When I’m standing in the store, staring at the thousands of choices, I love having Think Dirty in my back pocket
- [R59] Useful information!: I appreciate being able to scan products in the store. And if a product is not in Think Dirty’s database, I can scan it and add it; they do the research it and get back to me, great support!
- [R172] Super helpful tool!: I love being able to check on products while I’m out shopping. So glad my daughter introduced me to this app!
- [R619] Good BUT needs improvement: I like this app and I use it a lot, and I add to lots of products to the database. Although It’d be appreciated since I am paying for this app, if the products were verified quicker, if the products were specified as American, Canadian, Euro, etc - because a lot of the products I've clicked to buy cant ship to my location and the link isn't correct to begin with, so hav
- [R1] User-driven database, but you pay: Was free, now they make you pay to use/search items. Why contribute when you have to pay? Makes no sense to have to pay for access to a database whose majority of items’ ratings are user-driven. Will be using & contributing to EWG from now on. Another “for-the-users,” “by-the-users” app bites the dust for shareholders.
- [R2] $$$: Money is all you want. You say you can search for free but that is not the truth, keyword search is only if you pay. Don’t say it’s free when it doesn’t function without paying.
- [R6] Doesn’t unlock: I have had this app for years. On two separate occasions I paid to upgrade but nothing changed from the free version. I was still not able to view my upgrade access. Once Apple returned my $. Now the app changed and I can’t search for free. Only scan in store. My goal is to find clean beauty products for my kids. I have moved to other apps. I don’t mind paying a fee, but not if it
- [R7] Premium subscription sux: I paid for the "premium" subscription with "unlimited scans" but many products are locked behind the higher tier pay wall. The limited capabilities of the "premium" tier don't justify its cost and the app is completely unusable without paying. Unsubscribed and deleted.
- [R44] Horrible way to treat your highest paying customers - Plays DIRTY: I purchased this app last year and paid for the highest-tier subscription available at the time, which promised access to all features. A few months later, when I went to use the app again, I was shocked to find that I was suddenly blocked from features I had already paid for. It turns out the company added new subscription tiers
- [R77] Good idea, bad UX: The data in the app is great…if you can access it. I’ve got the highest subscription level you can get and yet I still can’t access numerous products. Incredibly frustrating.
- [R3] Bugs need to be fixed: Most of the products I scanned either didn’t show up or were the wrong thing. I think this is probably a new app and a lot needs to be done. But thank you for thinking about the consumers.
- [R20] Bad: Not good. It has very little actual products that scan and I don’t recommend.
- [R23] Pretty good app: It’s good, though they don’t have everything. Not surprising though, because why would they have every product lol. Good app in general though
- [R27] Mainly commercial products: It’s great if it’s a very well known brand. But I didn’t find it helpful for lesser known commercial-brands.
- [R30] Unreliable: I review ingredients directly from the product itself and compare it to the ingredients listed on this app, and the majority of the time the ingredients listed on the app are incorrect. It’s unreliable information.
- [R84] Needs improvement / And staff unresponsive to concerns: I have emailed the company about this before. The list of ingredients are often not 100% complete. I’ve seen several products that have a green rating and then I compared the listed ingredients on the app to the ingredients on the actual bottle and the app is missing some of the ingredients. That means the rating may not be accurate if some o
- [R96] False indicators: Cancelling and stopping payment for false claims! There is no way on Gods green earth that Tide, OxiClean, Downy, Snuggle, and many other products have a 0 green rating for harmfulness!!
- [R105] Disappointed: I have been using this app for years and I thought it was fairly good with checking products and giving products a rating on the toxic scale. But recently I have been questioning how good it actually is and wether or not they are really checking products ingredients and there affects on our body! For instance, they regularly give products a 1-3 score even if they contain fragrance/pe
- [R37] Poor quality app.: Don’t waste your money. This app does not do what it is supposed to do. You scan the barcode for the item and then it asks you to fill in the ingredients rather than it, providing the ingredient list based on the barcode. If I wanted an app where I had to do the work for it, this is a great one, but I want the app to provide the information to me.
- [R18] Pure and Clean Skin: Awesome app, easy to use and informative for your health. It helped me to take care of my largest organ, and my body health in general.
- [R78] Can’t access premium: I’m unable to access my premium subscription. I reported this a few … months ago, but never get a reply. I just reported it again and get a ‘thanks for your feedback’. It is a long standing issue, not feedback. This is resolved. The actual app is great and I will continue to use it.
- [R10] Not free: I can’t look anything up without it wanting me to upgrade. Before it did that, anything I DID look up was locked. Worthless app. Downloaded and uninstalling all in a matter of 5 minutes. Thanks for nothing.
- [R24] 👎: Does a good job but the fact that they have added a subscription that makes you pay for basic information is ridiculous. There are plenty of other competing apps with free information. Will never be redownloading or recommending to anyone. Bye.
- [R36] Great app: Pricing gouging for useful information. It use to be $3 for full app usage, now it is more for the same information
- [R68] Pricey: This app is free to download, but costs $199/year if you actually want to use it. Get EWG Healthy Living to scan things and get info FOR FREE.
- [R38] Too many locked out reviews.: Seems like 50% of what I’m looking for are not in the database.
- [R64] Built for female products: Might be good for female products. But everything I scanned for male products came up as “not in our system yet”.
