This app is super helpful for people learning different "dirty" ingredients in daily products! I wish the free version would have a little more input, but, still a great app!

The app seemed pretty extensive, and I was impressed with the amount of information available on each ingredient. However, after the 1st scan, all information and options were "locked" unless I agreed to a free trial of premium. The option to add your "preferred ingredients" wasn't ever an option, and when cross checked with the Yuka app, it seemed like it was pretty off the mark. (although Yuka is aimed more towards being vegan, etc). Deleted it, but if you're willing to pay, it seems good.

I've been using this app for years....I LOVED it it was super nice to easily scan and know what to worry or not worry about. Now I find out you have to pay to get any information. Not cool.

I REALLY want to love this app, BUT when I'm looking at face primer and click on "our picks" I expect alternatives NOT lotion, cleanser, mascara, and anything other than primer! Also, when scanning bar codes to check items like toothpaste, shampoo, hair gels, and such I am having to enter so much information & it definitely takes more than "just a minute" of my time. KEEP TRYING UPDATE: It took 3 YEARS and 5 months for a reply that said they're working on it ... 😶
