What is the app that tells you if products are toxic?

Excuse me, could you please elaborate on the app that alerts users about the toxicity of products? Is it a smartphone application that scans product barcodes or QR codes to provide information on potentially harmful ingredients or substances? Is it available for both iOS and Android users? Additionally, does it rely on a comprehensive database of toxic substances and products, ensuring accuracy and reliability for its users? I'm curious about how it functions and the benefits it offers to consumers concerned about their health and safety.
