ReefReceipt

ReefReceipt is a mobile app (with a lightweight web dashboard) that helps divers, snorkelers, and coastal travelers quickly check whether sunscreens and personal-care products are likely to harm coral reefs. Users scan a barcode or search a product name to see ingredient flags (e.g., oxybenzone, octinoxate), local regulation notes by destination, and a plain-language “why it matters” summary. The app also suggests safer alternatives available in nearby stores or online, and lets users save a travel kit list per trip. An AI layer helps normalize messy ingredient lists from photos, receipts, and different regional labeling formats, but the core value is a curated, auditable ingredient ruleset with citations. This is not a magical “save the ocean” app; it’s a practical decision tool that reduces confusion and greenwashing at the point of purchase.
