I saw this first link mentioned by Homa ...
"FARE Changes Corporate Sponsorship Page After Test Results and ContentChecked Admission"
http://snacksafely.com/2014/12/fare-changes-corporate-sponsorship-policy-after-test-results-and-contentchecked-admission/ (http://snacksafely.com/2014/12/fare-changes-corporate-sponsorship-policy-after-test-results-and-contentchecked-admission/)
QuoteIn tests, ContentChecked declared a series of common food products "free from peanuts" despite clearly visible "may contain peanuts" warnings on their labels.
QuoteSnackSafely.com is in the process of initiating actions with Consumer Reports, the Better Business Bureau, and the NJ Attorney General's Office.

but then I saw this 2nd "correction" post ...
"Fair is Fare: We Stand Corrected"
http://snacksafely.com/2014/12/fair-is-fare-we-stand-corrected/ (http://snacksafely.com/2014/12/fair-is-fare-we-stand-corrected/)
QuoteAfter publishing the results of our test of the ContentChecked and Wazinit apps in which both apps misidentified a series of products bearing "may contain" warnings as "free from", we approached FARE because of what appeared to be a tacit endorsement of ContentChecked's app that accompanied the firm's logo on their Corporate Partners page
----------------------
Anyway ... seems to be an issue ... I never felt comfy with those types of apps.
Always read the label!
