Ratings and Reviews
Useful app for a naturally cleaner lifestyle
This app is useful to find naturally driven products as opposed to a more chemical based product available in many stores. The only issue is, the app will rate a product low, then in a larger size or a different scent it is rated high. For example I was looking for a cleaner, truly greener laundry detergent, it included “all” brand, “free and clear”. The list rated it at a 3, when I scroll down, a bigger size of the exact same product, same ingredient, is rated an 8?! I think the app needs better regulation of products for higher integrity to all who use. This will ensure the products are up to date. I also learned a big name household company bought out the app, and now many of their products are listed lower, when it had a high rating before. Definitely look more into the products you wish to try. However the app is great for a quick comparison when you are choosing a better, honest, and of course natural selection for your family 😊
Needs to be updated. Very glitchy.
Loved this app at first. It seems they spend more time pushing the products they are sponsored by instead of cleaning up listed products and repairing the glitches. That’s fine if they are reliable products that work. Most seem like they do. I have found many products with conflicting ratings! Also products given a score with no ingredient information. They should not be listed if no reason for the score given. So many products I’ve searched for are not in the list. I submitted popular products many months ago to be reviewed and still are not shown. But I do understand the data base is constantly being updated. The comment review feature is a bust for me now. I am unable to read comments on the products. Not to mention it’s very glitchy and stops working every time I open it!
I gave it 3 stars because this app has a great foundation to work with and will be great once these major kinks are worked out.
Very misleading now pushing notices more than daily
I downloaded this app a few years ago after reading about it on a favorite bloggers site. She was very impressed. I checked a few things I use and a few things the blogger was throwing out. I have a BS, MS, and doctorate degree in the sciences. My masters is in Environmental Sciences. I have always worked in the biological sciences. I found the app information and scoring quite alarmist. Here’s an example. Selsun Blue is listed as toxic. The reason because it has Selenium. Selenium can be toxic. But it is also an essential mineral for animals. So just stating it is toxic is silly. A short exposure to selenium in your shampoo should not be harmful. In fact tinea versicolor a fungal infection of the skin can be treated by applying Selsun Blue to your skin and waiting 20 minutes before showering. So the suggestion that simple use of Selsun Blue as a dandruff shampoo is dangerous because it includes selenium is at least misleading.
I haven’t used the app in a few years.
What lead me to comment today is the fact that this app has started sending me notices. It is pushing products.
