Free app scans food label and gives a health rating

Called Yuka, it was developed by François Martin and others at yuka.io after an opinion poll said 80% of people found food labels unreadable.

Based on Nutri-score government five-colour ratings and OpenFood­Facts database, it uses marks out of 100, giving 60% for nutritional quality, 30% for additives and 10% for organic.

Yuka is free. It raises income through a nutrition plan and donations.
