Ratings and Reviews
THE BEST APP EVER-
I was so unaware of what I was bringing into my home. My cleaning products (all purpose cleaner & dish soaps, laundry soaps, etc.), body products (deodorant, shampoos, conditioners, facials, makeup, etc.) THEY WERE ALL TOXIC- and I had no idea. Some of these chemicals effect human hormones, skin sensitivity, and some chemicals lead to cancer & I didn’t even know they were in my home. I was uneducated which is the exact reason I am writing this review- once you know, you know & I guarantee once you know you will want better for your husband, your kids, yourself, and even the dog. TAKE ACTION! Download this app and use it to your best ability the app has a ranking scale from 0-10. 0 being the healthiest 10 being the MOST toxic. This is judged based upon the chemicals and products in your cleaners from home cleaners to body products too. All of my home products & body products were sitting at like an 8 or 9- which is really scary-
Now you know, and YOU should download this app && change your life.
The app is biased and not giving full info
A friend referred this app to me as an expecting mother. I got the app and started scanning and was appalled at what the app thought was dangerous. I did my research on some ingredients, carcinogens, health problems and whatnot. The app is very biased towards organic product. If it’s not organic, they will label is 8-10 and call it very dangerous. One of my products is labeled a Group 2B by the national Cancer society- there is a possibility of it having harmful effects towards humans but the studies were inconclusive since it was tested on animals and not humans. But the app said it was a 9- very dangerous. It’s good to know what is in your products, but the app doesn’t tell you how much exposure to a product you’d have to endure before seeing effects of the bad ingredients. For example, *possible* carcinogens are found in Johnson and Johnson baby body soap. But to see effects of those possible carcinogens, a baby would have to be exposed to thousands and thousands of gallons. And even then, it is only a slight possibility (less than .0001%) that the child would get cancer. The information the app provides is misleading and it’s in favor of organic products. I think the app producers get paid to rate those products as “heathy products.”

Thank you very much for your feedback on the app. We strive to be a wholly unbiased platform for users to gain information about the products they are using or considering as a purchase. We cross-reference ingredient information with lists of prohibited ingredients from government and non-profit health and environmental groups. Due to lack of formal government regulations, most of these lists are guidelines only, but they are backed by scientific studies with abstracts which are available to the public. We take the health impacts of cosmetics seriously, so if there’s enough evidence showing that even a single ingredient is unsafe, it will be listed as “Dirty” on the “Dirty Meter”. The ratings are strictly based on our own interpretation; other sources could have their own opinions. For more information, please tap the Ratings box on the Product screen, or you can also review our Terms of Service.
At the least it makes you think
I downloaded this app several years ago. I went on a scanning frenzy. It was both alarming & terrifying to read all the suspect ingredients that were in items I had assumed were for the most part safe, particularly skin care. One expects chemicals in cleaning products, but not your lotion or toothpaste or even laundry detergent. It also made me think about where all these chemicals end up, that is in our water supply & soil, basically they are assimilated into our environment one way or another. That is the real benefit of this app, it makes you stop & think. I have found that some of the rating is misleading & not fully accurate like they are trying to scare people. I do not like the persistent level that they push products on users. It seems to have increased significantly since I first downloaded the app. Also I had a ton of products scanned & submitted that were not in the system & they are all gone now. That is extremely frustrating to me. It takes time to input products. I check back occasionally to see if they have been rated & to find that they are all just gone was pretty crappy.

The recommendations shown in app are placed in priority as they have been manually vetted by the Think Dirty team. This means we have completed an in-depth review of each ingredient and deemed them to be safe and non-toxic. These partnerships, which are clearly indicated in-app, help keep our app free. We want to ensure everyone is able to access the information we provide. In no way are brands able to have their ratings changed without providing documentation regarding their ingredients being non-toxic.
