it WAS Great till update, now it doesn't recognize any barcodes. Was a life changer for me, now its a aggravating. UPDATE App is updated, duh still doesn't accept barcodes and majority of the time it doesn't recognize ingredients. Not worth messing with! I see it now as a waste of money and time trying to make it work!! It WAS Great, sad!

Hey Darcey, thanks for the info. Please update to version 4.0.6 and go to Options and activate Alternative Scanner. Let me know if it still doesn't work. Best regards, Jonah

Do not force me into a long onboarding flow. Let me skip it so I can look around. Immediately uninstalled due to this alone. I disagree that this is needed. I was trying to find out if the app would be useful for me and also how much it costs. These should be clearly laid out before having to go through a huge, long, required flow.

Thanks for your suggestion. To see how the app works or doesn't work, it first needs to know what you tolerate/can't tolerate.

The app is extremely easy to use and is well designed/intuitive to use. The developer is very friendly and helpful--he answered an email when I reached out to him. There have been a few occasions when it hasn't flagged something correctly (for example, misreading something with coconut milk as "not compatible" because it had "milk"), but reporting errors is very easy and I expect these issues will disappear as more people use the app. Would definitely highly recommend to others!
