DietSensor's default language is English. Only the French devices will allow DietSensor to show the default language as French.
You can change the language of the food database you are searching for by going to the menu and changing the 'Database Language' in the 'Settings' menu. This will allow you to search in a language other than English or French. We recommend you use the language of the country that was selected as the database country, because all branded and restaurant foods are often recorded in that country's language.
