  1. [R5] Yuka 5/5 · US First time knowing this app: I never knew something like this and it’s so good that is not and add app like a lot much others, it gives you a range of options and prices, I love it!!
  2. [R6] Yuka 3/5 · US It’s okay: Only can scan with qr code and 80 percent of the items You want to see are healthy or not aren’t registered in the app you can’t search anything up unless you have premium which you need to pay for and all ingredients with high protein that you want to see if healthy or no are not scanned unless they’re 19 grams of protein or less
  3. [R9] Yuka 3/5 · US Amazing! But some things to know…: Yuka is great! I love how you can scan an item to see the good or the bad about it, I like how you can see the better option for foodsor beauty products, but it could be better with a meal planner, or a tracker on what you have been eating and what you should eat off a menu or what’s the best option is. Overall, I give this app a 6.5/10!
  4. [R11] Yuka 5/5 · US I love Yuka: Mi hija me paso ésta aplicación y ha sido lo mejor que me puede haber pasado, puedes chequear tus productos y saber que realmente estás pagando por lo que contiene el producto y no por una marca, se los recomiendo a todos Uds . I love YUKA
  5. [R1] Yuka 2/5 · US Buyer beware. I don’t trust it.: I loved it at first. Especially since it gave “good” alternatives. However. I noticed something. The same exact product would be listed more than once. One would say ‘good’ or ‘excellent’ and the next would like say ‘bad’ or ‘poor’. The same exact product. No I don’t trust anything the app says. And I paid for the year last month so I could search. Didn’t notice th
  6. [R7] Yuka 1/5 · US Bad advice: Literally gave a food a 0 when the serving size literally had much lower than daily required values of fats, minerals, and sodium. Yet it gives mainstream chips 50+ for many variants when those are the worst of the worst. This app has no context for anything else you’re eating. Most things it says are bad are actually needed in moderation. Update: they responded with “we measure every
  7. [R13] Yuka 1/5 · US Horrible: I scanned a few products, that it rated low… but it recommended worse products to me. It’s important to know which additives are good and bad, and this app clearly doesn’t know. 100% wouldn’t recommend
  8. [R15] Yuka 3/5 · US It’s mid: OK, so it’s good but the only problem is so I have this eczema lotion and I was seeing if it’s good and then I was looking at the recommendations cause it rated poor the recommendations had nothing to do with eczema so some other products that you need for certain stuff was not the recommendations we’re not showing what you need for that type of condition that you have but I’m overall it
  9. [R4] Yuka 1/5 · US Frustrating App: This app makes you sign in every time you open it. Half the time after you sign it makes you sign in again. Too frustrating.
  10. [R12] Yuka 3/5 · US Helpful but hard to contribute: It’s easy to find items and see the score. Good for seeing if a product has any issues. I get a lot of products with simple ingredients that are not registered. I was trying to add vanman’s beef tallow soap that has only four ingredients. I had to take a picture of the ingredients and the app could not validate. Very frustrating since there wasn’t another way to a
  11. [R14] Yuka 4/5 · US Amazing app but…: The app is amazing. I use it all the time except for when It won’t work. I mean like the app won’t load. Can’t be downloaded or used on WiFi or cell. So Yuka. You need to fix something. This has gone on since I started using it over a year ago. Would be a 5 star review if it worked more often
  12. [R16] Yuka 1/5 · US Mandatory refer to unlock the app: Why do I need to refer the app to a friend in order to unlock 99% of the app. Waste of time.
  13. [R25] Yuka 1/5 · US Member price misleading: I really enjoy using Yuka and appreciate the work that goes into the app. One small suggestion: the membership page says “Pay what you want,” but the slider appears to have a minimum payment of $10/year and only allows higher amounts. The wording made me think I could choose any amount, including less than $10. Consider changing it to something like “Choose your membership
  14. [R26] Yuka 5/5 · US What a great TOOL: The YUKA App … I started with the free version but after using it so much I went for the paid subscription. It has changed how I shop for my food and later…cosmetic type items like sunscreens! The big reason for me to do a paid subscription is that I can manually search for the ratings of a particular product by hand vs needing to scan a bar code. I find if an item I am trying
  15. [R37] Yuka 1/5 · US Must pay $15 membership: Not free, $15 membership a year to join. deleting app to avoid additional charges
  16. [R2] Yuka 5/5 · US Got a Question?: I got an email response to my question within 24hrs!!! It was super helpful and friendly so don’t hesitate to ask a question about any product you want more information about. Love this app and their customer service!
  17. [R3] Yuka 3/5 · US Colombia!!: I sent a request to the developer to help with the colombian database but no reply back yet :(
  18. [R84] Think Dirty 3/5 · US 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
  19. [R116] Think Dirty 5/5 · US What: Can’t get a hold of anyone to ask questions
  20. [R93] Think Dirty 3/5 · US 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
  21. [R102] Think Dirty 3/5 · US User submissions misleading: This app seems to be helpful, however, I’ve been finding a lot of ‘user submissions’ that don’t accurately list the ingredients. For example, Tide laundry detergent was rated a 0 (that’s great right?!) however the only ingredient the user submitted was water…. Hmm that doesn’t seem right.
  22. [R109] Think Dirty 2/5 · US 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.
  23. [R18] Yuka 3/5 · US Inconsistency: Santa Cruz dark roasted … 94/100. Santa Cruz creamy … 72/100? Exact same ingredient profile. Exact same nutrition. lol. Like this app makes no sense whatsoever the scoring system is so fundamentally flawed it hilarious
  24. [R61] Think Dirty 1/5 · US 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.
  25. [R64] Think Dirty 1/5 · US $$$: 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.
  26. [R73] Think Dirty 1/5 · US 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.
  27. [R76] Think Dirty 1/5 · US Use to be helpful: I loved this app when I first started using it because it was an easy way for me to overhaul my beauty products for clean options. The reason I am giving it just 1 star is because they have switched to an option that will allow a person to see which products are clean only if you pay a subscription. This doesn’t make the app as user friendly as it use to be.
