This app has been very helpful in helping me to narrow down foods can get at the grocery store. I did a store visot where all I did was scan foods I usually bought or was thinking of buying to rule out the bad ones. Ended up finding some surprises that I could have! So far the only issue I've seen is when it scans ingredients, Durum wheat gets flagged as Rum lol

Excellent app. With the pro edition you can set what you are intolerant/allergic too. I mainly use the ingredient scanner as it will outline what you are intolerant/allergic to in the ingredients on the screen. The scan and search is extremely quick. With age, everything, including ingredients list font size, is getting smaller or is printed on the wrong color background so you can't read it. The developer was responsive when I emailed about two foods I couldn't find on the list.

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!
