horrible app. did the trial. could not scan anything via barcode or photo. had to do it manually. who is going to go to the grocery store, buy more than 50 items and stand there manually enter info in, when the product has a barcode. there were a few products that I felt the info was dubious. icons are small and covered up by my phones system icons. it didn't look like you could personalize the app either. I like my screen in dark mode.

There's pay wall on just about everything. I'm currently interested in the water. It'd make more sense if they had 10-20% unlocked and then pay for a fully unlocked version. That way people could actually have something to work with to decide if its worth the membership. As is though, its pretty much an instant uninstall. I can do my own research for free. Just figured the app was a cool idea.

Personally, I think the app is great. I love the aspect and overall creation of it, and it is probably one of the most important tools needed nowadays because of the stuff in major products. But, I don't thinking paying for it is necessary. 3 days free, alright, but why do I have to pay for it in the first place? I understand the cost of making this app and independent lab tests, but I just can't do the monthly payment like being healthy is a subscription. Its the same agenda as everything else.
