Ratings and reviews

I loaded the ap and gave way more personal information than I should have to, only to find that the bar-code scanning process did not work. I tried several suppliments (from major national companies), and the scanning could not recognize any of them. I immediately closed the ap and scanned them with the normal bar code reader, and it read them in a second, over and over. It's too bad, as this would have been a useful tool. Very disappointed!

As of 5/11/25, still no resolve. * Help! I've been trying to get help logging into my Premium account since 2/2/25. I have loved using the free version of this app for years and finally decided to go all in. So far, the difficulty in contacting customer service is frustrating. I just want to be able to login and utilize the app with the advanced Premium functions, and get a credit for the last 2 months. Is there someone that can help me besides the generic customer service email, please? Thanks!

The most disappointing thing is how few products are reviewed by people and haven't been through manual vetting. The score is given based on the ingredients, but those are user uploaded. If you want to see where a product is available, links only take you to amazon the "keep the app free," but after you pay for it, amazon is still your only option.
