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

there's a lot of products (most common ones) that are not listed. it's also annoying that i can't turn off the dailynotifications. I'll look if i want to! UI on this is ok, needs work. FYI, keyboard takes up half the screen. i know u can tap away, but that means you need to change the layout so you van view the sections easier. feels like a hybrid platform.

Great idea, terribly executed. None of my products are listed, the scanner doesnt work and the search function is horrible. If you're looking for a specific brand they tailor your results to their advertised products. If I'm looking for "NYX" it brings up all their advertised products containing an N,Y or X instead of looking for the whole word. You have to scroll around to find the brand you're looking for. Then when you actually get in the realm of what you want they only have 1 or 2 things.
