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.

as soon as I download it, they want a review. how can I review it if I haven't even used it yet. and you have to pay a membership so you can have full access. I scanned my first item, it was a great value water bottle and results were herbalife protein powder. I already want to uninstall it.

I really want to love this app! There is thorough information behind tons of products readily available so you can really shop smart! The reason behind my review is that I experienced this app to be very buggy on my device. I have attempted to reinstall it, but I recieve a lot of failed loads to blank pages or an error screen. It has gotten to the point where it makes the app a little unusable on my end. Hoping for an update as I really love the idea behind the app!
