Igrass PTY Ltd.
Offers a self-contained database (no wireless connection needed) in which users can look up food additives found in products.
Very easy to use and offers a lot of information on the additives searched. The one disadvantage is that the free version only has 50 additives. Users must purchase the full version for the 450+ additive database.
Overall Impressions from Around the Web:
Positive feedback with a staff recommend from the iTunes store. Also upgraded to integrate more closely with Wikipedia and includes a more comprehensive list with both harmful and harmless additives. Reviewed positively on Babble.com, a parenting website.
