Peanut Allergy alternatives and competitors

Peanut Allergy is a deadly simple app to inform food-makers of your peanut allergy while traveling abroad. Type a country, and get the translation of "I am allergic to Peanuts". Done. Main fact: works OFFLINE. I am allergic to peanuts, and I had been looking for such a tool for quite a while so I built it myself. I am very open to suggestions !!!
